Key distillation from Gaussian states by Gaussian operations  

E-Print Network (OSTI)

We study the secrecy properties of Gaussian states under Gaussian operations. Although such operations are useless for quantum distillation, we prove that it is possible to distill a secret key secure against any attack from sufficiently entangled Gaussian states with non-positive partial transposition. Moreover, all such states allow for key distillation, when Eve is assumed to perform finite-size coherent attacks before the reconciliation process.

Local Gaussian operations can enhance continuous-variable entanglement distillation  

Science Conference Proceedings (OSTI)

Entanglement distillation is a fundamental building block in long-distance quantum communication. Though known to be useless on their own for distilling Gaussian entangled states, local Gaussian operations may still help to improve non-Gaussian entanglement distillation schemes. Here we show that by applying local squeezing operations both the performance and the efficiency of existing distillation protocols can be enhanced. We find that such an enhancement through local Gaussian unitaries can be obtained even when the initially shared Gaussian entangled states are mixed, as, for instance, after their distribution through a lossy-fiber communication channel.

Energy Use in Distillation Operation: Nonlinear Economic Effects  

E-Print Network (OSTI)

Distillation operations are major consumers of energy, by some estimates comprising forty percent of the energy usage in the refining and chemicals industry. Obtaining the maximum energy efficiency from this unit operation is obviously very important. For many distillation columns there is a tradeoff in operation between energy usage and product recovery and setting the proper usage target involves a calculation of the economic tradeoff between these two factors. However, distillation is a non-linear process and normal economic evaluations add more non-linearities to the economic objective functions. In addition, the normal product quality variability observed leads to requirements for statistical evaluation. Hence, calculation of the correct target can be complicated. In this paper, these non-linear economic effects are reviewed and techniques to calculate the correct usage targets presented.

Multipartite nonlocality distillation  

Science Conference Proceedings (OSTI)

The stronger nonlocality than that allowed in quantum theory can provide an advantage in information processing and computation. Since quantum entanglement is distillable, can nonlocality be distilled in the nonsignalling condition? The answer is positive in the bipartite case. In this article the distillability of the multipartite nonlocality is investigated. We propose a distillation protocol solely exploiting xor operations on output bits. The probability-distribution vectors and matrix are introduced to tackle the correlators. It is shown that only the correlators with extreme values can survive the distillation process. As the main result, the amplified nonlocality cannot maximally violate any Bell-type inequality. Accordingly, a distillability criterion in the postquantum region is proposed.

Lumpy capacity investment and disinvestment dynamics’, Operations Research forthcoming  

E-Print Network (OSTI)

Capacity addition and withdrawal decisions are among the most important strategic decisions made by …rms in oligopolistic industries. In this paper, we develop and analyze a fully dynamic model of an oligopolistic industry with lumpy capacity and lumpy investment/disinvestment. We use our model to answer two questions. First, what economic factors facilitate preemption races? Second, what economic factors facilitate capacity coordination? We show that low product di¤erentiation, low investment sunkness, and high depreciation promote preemption races. We also show that low product di¤erentiation and low investment sunkness promote capacity coordination. Although depreciation removes capacity, it may impede capacity coordination. Finally, we show that, at least over some range of parameter values, …rms’expectation plays a key role in determining whether or not industry dynamics are characterized by preemption races and capacity coordination. Taken together, our results suggest that preemption races and excess capacity in the short run often go hand-in-hand with capacity coordination in the long run. We thank Je ¤ Campbell, Ron Borkovsky, and Steve Kryukov for helpful comments and discussions. Besanko

Advanced Distillation Final Report  

Science Conference Proceedings (OSTI)

The Advanced Distillation project was concluded on December 31, 2009. This U.S. Department of Energy (DOE) funded project was completed successfully and within budget during a timeline approved by DOE project managers, which included a one year extension to the initial ending date. The subject technology, Microchannel Process Technology (MPT) distillation, was expected to provide both capital and operating cost savings compared to conventional distillation technology. With efforts from Velocys and its project partners, MPT distillation was successfully demonstrated at a laboratory scale and its energy savings potential was calculated. While many objectives established at the beginning of the project were met, the project was only partially successful. At the conclusion, it appears that MPT distillation is not a good fit for the targeted separation of ethane and ethylene in large-scale ethylene production facilities, as greater advantages were seen for smaller scale distillations. Early in the project, work involved flowsheet analyses to discern the economic viability of ethane-ethylene MPT distillation and develop strategies for maximizing its impact on the economics of the process. This study confirmed that through modification to standard operating processes, MPT can enable net energy savings in excess of 20%. This advantage was used by ABB Lumus to determine the potential impact of MPT distillation on the ethane-ethylene market. The study indicated that a substantial market exists if the energy saving could be realized and if installed capital cost of MPT distillation was on par or less than conventional technology. Unfortunately, it was determined that the large number of MPT distillation units needed to perform ethane-ethylene separation for world-scale ethylene facilities, makes the targeted separation a poor fit for the technology in this application at the current state of manufacturing costs. Over the course of the project, distillation experiments were performed with the targeted mixture, ethane-ethylene, as well as with analogous low relative volatility systems: cyclohexane-hexane and cyclopentane-pentane. Devices and test stands were specifically designed for these efforts. Development progressed from experiments and models considering sections of a full scale device to the design, fabrication, and operation of a single-channel distillation unit with integrated heat transfer. Throughout the project, analytical and numerical models and Computational Fluid Dynamics (CFD) simulations were validated with experiments in the process of developing this platform technology. Experimental trials demonstrated steady and controllable distillation for a variety of process conditions. Values of Height-to-an-Equivalent Theoretical Plate (HETP) ranging from less than 0.5 inch to a few inches were experimentally proven, demonstrating a ten-fold performance enhancement relative to conventional distillation. This improvement, while substantial, is not sufficient for MPT distillation to displace very large scale distillation trains. Fortunately, parallel efforts in the area of business development have yielded other applications for MPT distillation, including smaller scale separations that benefit from the flowsheet flexibility offered by the technology. Talks with multiple potential partners are underway. Their outcome will also help determine the path ahead for MPT distillation.

Distillate Fuel Oil Assessment for Winter 1995-1996  

Gasoline and Diesel Fuel Update (EIA)

U.S. Refining Capacity Utilization U.S. Refining Capacity Utilization by Tancred Lidderdale, Nancy Masterson, and Nicholas Dazzo* U.S. crude oil refinery utilization rates have steadily increased since oil price and allocation decontrol in 1981. The annual average atmospheric distillation utilization rate has increased from 68.6 percent of operable capacity in 1981 to 92.6 percent in 1994. The distillation utilization rate reached a peak of 96.4 percent in August 1994, the highest one-month average rate in over 20 years. This dramatic increase in refining capacity utilization has stimulated a growing interest in the ability of U.S. refineries to supply domestic requirements for finished petroleum products.

Optimization approach to entanglement distillation  

E-Print Network (OSTI)

We put forward a method for optimized distillation of partly entangled pairs of qubits into a smaller number of more entangled pairs by recurrent local unitary operations and projections. Optimized distillation is achieved by minimization of a cost function with up to 30 real parameters, which is chosen to be sensitive to the fidelity and the projection probability at each step. We show that in many cases this approach can significantly improve the distillation efficiency in comparison to the present methods.

High energy bursts from a solid state laser operated in the heat capacity limited regime  

DOE Patents (OSTI)

High energy bursts are produced from a solid state laser operated in a heat capacity limited regime. Instead of cooling the laser, the active medium is thermally well isolated. As a result, the active medium will heat up until it reaches some maximum acceptable temperature. The waste heat is stored in the active medium itself. Therefore, the amount of energy the laser can put out during operation is proportional to its mass, the heat capacity of the active medium, and the temperature difference over which it is being operated. The high energy burst capacity of a heat capacity operated solid state laser, together with the absence of a heavy, power consuming steady state cooling system for the active medium, will make a variety of applications possible. Alternately, cooling takes place during a separate sequence when the laser is not operating. Industrial applications include new material working processes.

Distillation Column Flooding Predictor  

SciTech Connect

The Flooding Predictor™ is a patented advanced control technology proven in research at the Separations Research Program, University of Texas at Austin, to increase distillation column throughput by over 6%, while also increasing energy efficiency by 10%. The research was conducted under a U. S. Department of Energy Cooperative Agreement awarded to George Dzyacky of 2ndpoint, LLC. The Flooding Predictor™ works by detecting the incipient flood point and controlling the column closer to its actual hydraulic limit than historical practices have allowed. Further, the technology uses existing column instrumentation, meaning no additional refining infrastructure is required. Refiners often push distillation columns to maximize throughput, improve separation, or simply to achieve day-to-day optimization. Attempting to achieve such operating objectives is a tricky undertaking that can result in flooding. Operators and advanced control strategies alike rely on the conventional use of delta-pressure instrumentation to approximate the column’s approach to flood. But column delta-pressure is more an inference of the column’s approach to flood than it is an actual measurement of it. As a consequence, delta pressure limits are established conservatively in order to operate in a regime where the column is never expected to flood. As a result, there is much “left on the table” when operating in such a regime, i.e. the capacity difference between controlling the column to an upper delta-pressure limit and controlling it to the actual hydraulic limit. The Flooding Predictor™, an innovative pattern recognition technology, controls columns at their actual hydraulic limit, which research shows leads to a throughput increase of over 6%. Controlling closer to the hydraulic limit also permits operation in a sweet spot of increased energy-efficiency. In this region of increased column loading, the Flooding Predictor is able to exploit the benefits of higher liquid/vapor traffic that produce increased contact area and lead to substantial increases in separation efficiency – which translates to a 10% increase in energy efficiency on a BTU/bbl basis. The Flooding Predictor™ operates on the principle that between five to sixty minutes in advance of a flooding event, certain column variables experience an oscillation, a pre-flood pattern. The pattern recognition system of the Flooding Predictor™ utilizes the mathematical first derivative of certain column variables to identify the column’s pre-flood pattern(s). This pattern is a very brief, highly repeatable, simultaneous movement among the derivative values of certain column variables. While all column variables experience negligible random noise generated from the natural frequency of the process, subtle pre-flood patterns are revealed among sub-sets of the derivative values of column variables as the column approaches its hydraulic limit. The sub-set of column variables that comprise the pre-flood pattern is identified empirically through in a two-step process. First, 2ndpoint’s proprietary off-line analysis tool is used to mine historical data for pre-flood patterns. Second, the column is flood-tested to fine-tune the pattern recognition for commissioning. Then the Flooding Predictor™ is implemented as closed-loop advanced control strategy on the plant’s distributed control system (DCS), thus automating control of the column at its hydraulic limit.

Estimates of emergency operating capacity in US manufacturing and nonmanufacturing industries - Volume 1: Concepts and Methodology  

SciTech Connect

Development of integrated mobilization preparedness policies requires planning estimates of available productive capacity during national emergency conditions. Such estimates must be developed in a manner to allow evaluation of current trends in capacity and the consideration of uncertainties in various data inputs and in engineering assumptions. This study developed estimates of emergency operating capacity (EOC) for 446 manufacturing industries at the 4-digit Standard Industrial Classification (SIC) level of aggregation and for 24 key nonmanufacturing sectors. This volume lays out the general concepts and methods used to develop the emergency operating estimates. The historical analysis of capacity extends from 1974 through 1986. Some nonmanufacturing industries are included. In addition to mining and utilities, key industries in transportation, communication, and services were analyzed. Physical capacity and efficiency of production were measured. 3 refs., 2 figs., 12 tabs. (JF)

Low Energy Distillation Schemes  

E-Print Network (OSTI)

In this paper we look at various options available for the reduction of energy consumption in distillation systems. For binary systems, we look at how heat pumps can be used. With multi-component systems, process integration offers a means of reducing energy consumption. We look at how the better integrated distillation schemes can be quickly identified. It is found that the design of integrated schemes is quicker than that of non-integrated schemes. We then look at how the use of heat pumps, non-isobaric operation and divided wall columns may be incorporated into the synthesis of multi-component separation schemes. It will be seen that process integration provides an important means of reducing energy consumption in distillation processes. However, its conventional use requires the installation of piping (and pipes carrying vapor streams tend to be of large diameter and are consequently expensive). So, finally we examine a way in which the capital cost of such systems can be reduced: the divided wall column.

Reducing Energy Usage in Extractive Distillation  

E-Print Network (OSTI)

Butadiene 1:3 is separated from other C4-hydrocarbons by extractive distillation in a sieve plate tower. Prior to the development work to be described, the pressure in the extraction tower was controlled at a fixed value. The tower pressure-boilup control loop did not behave satisfactorily in the presence of non-condensables which entered with the feed. The capacity of the flooded reflux drum condenser for the tower was limiting production during summer months. The tower pressure control loop was put on manual. The pressure was allowed to drop to its lowest attainable value for the existing conditions of boilup and condenser cooling capability. This manner of operation is known as floating pressure control. By taking advantage of the higher relative volatility at the lower tower pressure, energy usage was reduced and there was an increase in production capacity. The tower operation at a lower temperature reduced tower and reboiler fouling. Substantial savings have resulted from these improvements. The annual energy consumption has been reduced by 25% and maximum productive capacity is higher by 15%. The rate of tower and reboiler fouling has not been fully quantified but is greatly reduced. A more stable tower operation has also contributed to higher productivity and reduced energy usage. Venting of non-condensables does not affect tower stability and the operators have adapted well to the new control strategy.

We consider controllability of two conjugate observables Z and X by two parties with classical communication. The ability is specified by two alternative tasks, (i) agreement on Z and (ii) preparation of an eigenstate of X with use of an extra communication channel. We prove that their feasibility is equivalent to that of key distillation if the extra channel is quantum, and to that of entanglement distillation if it is classical. This clarifies the distinction between two entanglement measures, distillable key and distillable entanglement.

Solid state laser technology is a very well developed field and numerous embodiments and modes of operation have been demonstrated. A more recent development has been the pumping of a solid state laser active medium with an array of diode lasers (diode pumping, for short). These diode pump packages have previously been developed to pump solid state lasers with good efficiency, but low average power. This invention is a method and the resulting apparatus for operating a solid state laser in the heat capacity mode. Instead of cooling the laser, the active medium will heat up until it reaches some maximum acceptable temperature. The waste heat is stored in the active medium itself.

Bounds for nonlocality distillation protocols  

Science Conference Proceedings (OSTI)

Nonlocality can be quantified by the violation of a Bell inequality. Since this violation may be amplified by local operations, an alternative measure has been proposed--distillable nonlocality. The alternative measure is difficult to calculate exactly due to the double exponential growth of the parameter space. In this paper, we give a way to bound the distillable nonlocality of a resource by the solutions to a related optimization problem. Our upper bounds are exponentially easier to compute than the exact value and are shown to be meaningful in general and tight in some cases.

Collocation Methods For Distillation Design  

E-Print Network (OSTI)

In this third paper on collocation methods for distillation design, we explore the use of the collocation models for design of simple distillation columns as well as flexible columns. Solvent recovery plants must deal with a wide range of feeds and still return pure solvents. The design problem we address is a single flexible column within the overall solvent recovery plant. We have developed the models and algorithms in the ASCEND system. We discuss the attributes and use of the ASCEND system. With ASCEND we can create complex models with simple building blocks and interactively learn to solve them. We found the collocation model an excellent tool for distillation design, allowing us to develop new concepts in design strategies. We designed a single column as would exist in a flexible solvent recovery plant for an azeotropic system. It was designed to handle three possible feeds, each with a distinct separation task. For each possible feed to a column, we approximate the operation of ...

Distillation of liquid fuels by thermogravimetry  

Science Conference Proceedings (OSTI)

In this paper, design and operation of a custom-built thermogravimetric apparatus for the distillation of liquid fuels are reported. Using a sensitive balance with scale of 0.001 g and ASTM distillation glassware, several petroleum and petroleum-derived samples have been analyzed by the thermogravimetric distillation method. When the ASTM distillation glassware is replaced by a micro-scale unit, sample size could be reduced from 100 g to 5-10 g. A computer program has been developed to transfer the data into a distillation plot, e.g. Weight Percent Distilled vs. Boiling Point. It also generates a report on the characteristic distillation parameters, such as, IBP (Initial Boiling Point), FBP (Final Boiling Point), and boiling point at 50 wt% distilled. Comparison of the boiling point distributions determined by TG (thermogravimetry) with those by SimDis GC (Simulated-Distillation Gas Chromatography) on two liquid fuel samples (i.e. a decanted oil and a filtered crude oil) are also discussed in this paper.

Estimates of emergency operating capacity in U.S. manufacturing industries: 1994--2005  

SciTech Connect

To develop integrated policies for mobilization preparedness, planners require estimates and projections of available productive capacity during national emergency conditions. This report develops projections of national emergency operating capacity (EOC) for 458 US manufacturing industries at the 4-digit Standard Industrial Classification (SIC) level. These measures are intended for use in planning models that are designed to predict the demands for detailed industry sectors that would occur under conditions such as a military mobilization or a major national disaster. This report is part of an ongoing series of studies prepared by the Pacific Northwest National Laboratory to support mobilization planning studies of the Federal Emergency Planning Agency/US Department of Defense (FEMA/DOD). Earlier sets of EOC estimates were developed in 1985 and 1991. This study presents estimates of EOC through 2005. As in the 1991 study, projections of capacity were based upon extrapolations of equipment capital stocks. The methodology uses time series regression models based on industry data to obtain a response function of industry capital stock to levels of industrial output. The distributed lag coefficients of these response function are then used with projected outputs to extrapolate the 1994 level of EOC. Projections of industrial outputs were taken from the intermediate-term forecast of the US economy prepared by INFORUM (Interindustry Forecasting Model, University of Maryland) in the spring of 1996.

The quantum capacity with symmetric side channels  

E-Print Network (OSTI)

We present an upper bound for the quantum channel capacity that is both additive and convex. Our bound can be interpreted as the capacity of a channel for high-fidelity quantum communication when assisted by a family of channels that have no capacity on their own. This family of assistance channels, which we call symmetric side channels, consists of all channels mapping symmetrically to their output and environment. The bound seems to be quite tight, and for degradable quantum channels it coincides with the unassisted channel capacity. Using this symmetric side channel capacity, we find new upper bounds on the capacity of the depolarizing channel. We also briefly indicate an analogous notion for distilling entanglement using the same class of (one-way) channels, yielding one of the few entanglement measures that is monotonic under local operations with one-way classical communication (1-LOCC), but not under the more general class of local operations with classical communication (LOCC).

Random multiparty entanglement distillation  

E-Print Network (OSTI)

We describe various results related to the random distillation of multiparty entangled states - that is, conversion of such states into entangled states shared between fewer parties, where those parties are not predetermined. In previous work [Phys. Rev. Lett. 98, 260501 (2007)] we showed that certain output states (namely Einstein-Podolsky-Rosen (EPR) pairs) could be reliably acquired from a prescribed initial multipartite state (namely the W state) via random distillation that could not be reliably created between predetermined parties. Here we provide a more rigorous definition of what constitutes ``advantageous'' random distillation. We show that random distillation is always advantageous for W-class three-qubit states (but only sometimes for Greenberger-Horne-Zeilinger (GHZ)-class states). We show that the general class of multiparty states known as symmetric Dicke states can be readily converted to many other states in the class via random distillation. Finally we show that random distillation is provab...

Advanced Distillation: Programs Proposed to DOE  

E-Print Network (OSTI)

EPRI has provided proposal preparation assistance and offered cost share funding assistance for two projects proposed in 2000. EPRI is highly interested, since this technology is applicable in all distillation systems, and since it will increase electric load in capacity increase revamps, probably the best economic targets in the U.S., since capital savings are best here. The approach can typically reduce energy use requirements, cooling (water) requirements, and environmental emissions per pound of distillate by 50%, while substantially reducing capital requirements for capacity increase revamps and new construction. If just 20% of all U.S. distillation were revamped by this approach as apposed to conventional, about 5x10^14 BTUs per year in energy use could be avoided, while increasing production by about 20%. Both the proposed petroleum refining (not awarded) and chemical industry programs and participants are described. As of this writing (1/31/01), chemical industry award selections have not yet been made.

Distillation: Present Status and Future Directions  

E-Print Network (OSTI)

Distillation will undoubtedly continue to be the most-used method for separating liquid mixtures, at any scale of operation. For this reason, and also because of its recognized energy intensiveness, distillation commands continued scrutiny with respect to cost-effective improvements. In this paper, the authors suggest fruitful areas of research that can lead to lower cost distillation separations. The areas of research are classified under the headings of phase equilibrium, material and energy balances, mass transfer efficiencies, equipment design, and system energy consumption. For each of the categories, a summary is given of the present status of the technology as well as directions that improvement-type investigations might take.

Army Solid State Laser Program: Design, Operation, and Mission Analysis for a Heat-Capacity Laser  

DOE Green Energy (OSTI)

Solid-state lasers have held great promise for the generation of high-average-power, high-quality output beams for a number of decades. However, the inherent difficulty of scaling the active solid-state gain media while continuing to provide efficient cooling has limited demonstrated powers to <5kW. Even at the maximum demonstrated average powers, the output is most often delivered as continuous wave (CW) or as small energy pulses at high pulse repetition frequency (PRF) and the beam divergence is typically >10X the diffraction limit. Challenges posed by optical distortions and depolarization arising from internal temperature gradients in the gain medium of a continuously cooled system are only increased for laser designs that would attempt to deliver the high average power in the form of high energy pulses (>25J) from a single coherent optical aperture. Although demonstrated phase-locking of multiple laser apertures may hold significant promise for the future scaling of solid-state laser systems,1 the continuing need for additional technical development and innovation coupled with the anticipated complexity of these systems effectively limits this approach for near-term multi-kW laser operation outside of a laboratory setting. We have developed and demonstrated a new operational mode for solid-state laser systems in which the cooling of the gain medium is separated in time from the lasing cycle. In ''heat-capacity'' operation, no cooling takes place during lasing. The gain medium is pumped very uniformly and the waste heat from the excitation process is stored in the solid-state gain medium. By depositing the heat on time scales that are short compared to thermal diffusion across the optical aperture, very high average power operation is possible while maintaining low optical distortions. After a lasing cycle, aggressive cooling can then take place in the absence of lasing, limited only by the fracture limit of the solid-state medium. This mode of operation is ideally suited for applications that require 1-30s engagements at very high average power. If necessary, multiple laser apertures can provide continuous operation. Land Combat mission analysis of a stressing air defense scenario including a dense attack of rockets, mortars, and artillery has indicated that multiple HEL weapon systems, based on the solid state, heat capacity laser concept, can provide significantly improved protection of high value battlefield assets. We will present EADSIM results for two government-supplied scenarios, one with temporally high threat density over a fairly large defended area, and one with fewer threats concentrating on a single defended asset. Implications for weapon system requirements will be presented. In order to demonstrate the operation of a high average power heat-capacity laser system, we have developed a flashlamp-pumped Nd:glass laser with output energies in the range of 500-1000J/pulse in a 10 x 10cm{sup 2} beam. With a repetition frequency of 20Hz, an average power of 13kW has been demonstrated for operational periods of up to 10s using a stable optical resonator (see enclosed figure). Using an M=1.4 unstable resonator, a beam divergence of 5X diffraction-limited has been measured with no active wavefront correction. An adaptively corrected unstable resonator that incorporates an intracavity deformable mirror controlled by feedback from an external wavefront sensor will provide <2X diffraction-limited output integrated over an entire 10s run at an average power of 10kW. A very similar laser architecture in which the Nd:glass is replaced by Nd:GGG and the flashlamps are replaced by large diode-laser arrays will enable the scaling of the output average power from the demonstrated 10kW to 100kW (500J/pulse at 200Hz). Risk reduction experiments for diode-pumped Nd:GGG, the fabrication of large Nd:GGG amplifier slabs, as well as the progress toward a sub-scale amplifier testbed pumped by diode arrays with total of 1MW peak power will also be presented.

Distillate Stocks Expected  

Gasoline and Diesel Fuel Update (EIA)

4 4 Notes: So let's get to what you want to know. What do we expect this upcoming winter? When EIA's demand forecast is combined with its outlook for production and net imports, distillate stocks are projected to remain towards the lower end of the normal range. We are forecasting about an 11 million barrel build between the end of July 2001 and the end of November 2001, slightly more than the average over the past 5 years (10 million barrels), but less than the average of the last 10 years (15 ½ million barrels). If, however, economic incentives are high enough, distillate stocks could build more, resulting in a higher distillate stock level heading into the winter. Of course, the reverse is true as well, if for example, the distillate fuel refining spread declines substantially. Since 1994,

AMMONIA DISTILLATION FOR DEUTERIUM SEPARATION  

SciTech Connect

The relative volatility or separation factor for deuterium enrichment in ammonia distillation was measured at several pressures and deuterium concentrations. The knowledge of this ingormation is very helpful in predicting costs of heawy water production by the ammonia distillation process. It hss been stated by others, that the ammonia distillation process of heawy water production would be competitive with other developed methods only if the actusl separation factor was at least 1.062 at low deuterium concentration. Ungortunately, the measurements do not indicate that the separation factor at low deuterium composition differs greatly from the vapor pressure pre diction ( alpha = 1.042). Deutero-ammonia was synthesized by isotopic exchange between natural ammonia and heavy water. Equilibrium determinations were made using an Othmer still, modified for low temperature operation, and a concentric tube fractionating column. The arnmonia samples were analyzed for deuterium content by converting them to water by flow torough hot copper oxide, followed by a differential density determination using the falling drop method.

Entanglement Distillation Protocols and Number Theory  

E-Print Network (OSTI)

We show that the analysis of entanglement distillation protocols for qudits of arbitrary dimension $D$ benefits from applying basic concepts from number theory, since the set $\\zdn$ associated to Bell diagonal states is a module rather than a vector space. We find that a partition of $\\zdn$ into divisor classes characterizes the invariant properties of mixed Bell diagonal states under local permutations. We construct a very general class of recursion protocols by means of unitary operations implementing these local permutations. We study these distillation protocols depending on whether we use twirling operations in the intermediate steps or not, and we study them both analitically and numerically with Monte Carlo methods. In the absence of twirling operations, we construct extensions of the quantum privacy algorithms valid for secure communications with qudits of any dimension $D$. When $D$ is a prime number, we show that distillation protocols are optimal both qualitatively and quantitatively.

This invention relates to an improvement in the process for the purification of caicium or magnesium containing an alkali metal as impurity, which comprises distiiling a batch of the mixture in two stages, the first stage distillation being carried out in the presence of an inert gas at an absolute pressure substantially greater than the vapor pressure of calcium or maguesium at the temperature of distillation, but less than the vaper pressure at that temperature of the alkali metal impurity so that only the alkali metal is vaporized and condensed on a condensing surface. A second stage distilso that substantially only the calcium or magnesium distills under its own vapor pressure only and condenses in solid form on a lower condensing surface.

Distillation of local purity from quantum states  

E-Print Network (OSTI)

Recently Horodecki et al. [Phys. Rev. Lett. 90, 100402 (2003)] introduced an important quantum information processing paradigm, in which two parties sharing many copies of the same bipartite quantum state distill local pure states, by means of local unitary operations assisted by a one-way (two-way) completely dephasing channel. Local pure states are a valuable resource from a thermodynamical point of view, since they allow thermal energy to be converted into work by local quantum heat engines. We give a simple information-theoretical characterization of the one-way distillable local purity, which turns out to be closely related to a previously known operational measure of classical correlations, the one-way distillable common randomness.

Engineering-Scale Distillation of Cadmium for Actinide Recovery  

Science Conference Proceedings (OSTI)

During the recovery of actinide products from spent nuclear fuel, cadmium is separated from the actinide products by a distillation process. Distillation occurs in an induction-heated furnace called a cathode processor capable of processing kilogram quantities of cadmium. Operating parameters have been established for sufficient recovery of the cadmium based on mass balance and product purity. A cadmium distillation rate similar to previous investigators has also been determined. The development of cadmium distillation for spent fuel treatment enhances the capabilities for actinide recovery processes.

Draft environmental impact statement for the siting, construction, and operation of New Production Reactor capacity. Volume 1, Summary  

Science Conference Proceedings (OSTI)

This Environmental Impact Statement (EIS) assesses the potential environmental impacts, both on a broad programmatic level and on a project-specific level, concerning a proposed action to provide new tritium production capacity to meet the nation`s nuclear defense requirements well into the 21st century. A capacity equivalent to that of about a 3,000-megawatt (thermal) heavy-water reactor was assumed as a reference basis for analysis in this EIS; this is the approximate capacity of the existing production reactors at DOE`s Savannah River Site near Aiken, South Carolina. The EIS programmatic alternatives address Departmental decisions to be made on whether to build new production facilities, whether to build one or more complexes, what size production capacity to provide, and when to provide this capacity. Project-specific impacts for siting, constructing, and operating new production reactor capacity are assessed for three alternative sites: the Hanford Site near Richland, Washington; the Idaho National Engineering Laboratory near Idaho Falls, Idaho; and the Savannah River Site. For each site, the impacts of three reactor technologies (and supporting facilities) are assessed: a heavy-water reactor, a light-water reactor, and a modular high-temperature gas-cooled reactor. Impacts of the no-action alternative also are assessed. The EIS evaluates impacts related to air quality; noise levels; surface water, groundwater, and wetlands; land use; recreation; visual environment; biotic resources; historical, archaeological, and cultural resources; socioeconomics; transportation; waste management; and human health and safety. The EIS describes in detail the potential radioactive releases from new production reactors and support facilities and assesses the potential doses to workers and the general public.

Non-Gaussian entanglement distillation for continuous variables  

E-Print Network (OSTI)

Entanglement distillation is an essential ingredient for long distance quantum communications. In the continuous variable setting, Gaussian states play major roles in quantum teleportation, quantum cloning and quantum cryptography. However, entanglement distillation from Gaussian states has not yet been demonstrated. It is made difficult by the no-go theorem stating that no Gaussian operation can distill Gaussian states. Here we demonstrate the entanglement distillation from Gaussian states by using measurement-induced non-Gaussian operations, circumventing the fundamental restriction of the no-go theorem. We observed a gain of entanglement as a result of conditional local subtraction of a single photon or two photons from a two-mode Gaussian state. Furthermore we confirmed that two-photon subtraction also improves Gaussian-like entanglement as specified by the Einstein-Podolsky-Rosen (EPR) correlation. This distilled entanglement can be further employed to downstream applications such as high fidelity quantum teleportation and a loophole-free Bell test.

Gulf Coast Distillate Production

4 of 15 4 of 15 Notes: PADD 3 is a major source of supply for the East Coast. This graph shows how during the winter of 1997-1998 when distillate stocks were very high, production fell back. In contrast, we entered the winter of 1996-1997 with very low stocks, and refineries reached record production levels as they tried to build stocks late in the season. Notice that production is normally reduced in January as distillate stocks are used to meet demand and as refineries begin maintenance and turnovers, which continue into February. This January is no different. There is room for some production increases in January and February, if refineries postpone maintenance. But postponing maintenance and turnarounds can create problems when the gasoline production season begins in March and April.

Methods of minimizing control input variations are used including column insulation, stillage-to-beer heat exchanger, and a steam pressure regulator.

Multilevel distillation of magic states for quantum computing  

E-Print Network (OSTI)

We develop a procedure for distilling magic states used in universal quantum computing that requires substantially fewer initial resources than prior schemes. Our distillation circuit is based on a family of concatenated quantum codes that possess a transversal Hadamard operation, enabling each of these codes to distill the eigenstate of the Hadamard operator. A crucial result of this design is that low-fidelity magic states can be consumed to purify other high-fidelity magic states to even higher fidelity, which we call "multilevel distillation." When distilling in the asymptotic regime of infidelity $\\epsilon \\rightarrow 0$ for each input magic state, the number of input magic states consumed on average to yield an output state with infidelity $O(\\epsilon^{2^r})$ approaches $2^r+1$, which comes close to saturating the conjectured bound in [Phys. Rev. A 86, 052329]. We show numerically that there exist multilevel protocols such that the average number of magic states consumed to distill from error rate $\\epsilon_{\\mathrm{in}} = 0.01$ to $\\epsilon_{\\mathrm{out}}$ in the range $10^{-5}$ to $10^{-40}$ is about $14\\log_{10}(1/\\epsilon_{\\mathrm{out}}) - 40$; the efficiency of multilevel distillation dominates all other reported protocols when distilling Hadamard magic states from initial infidelity 0.01 to any final infidelity below $10^{-7}$. These methods are an important advance for magic-state distillation circuits in high-performance quantum computing, and they provide insight into the limitations of nearly resource-optimal quantum error correction.

Interferometric distillation and determination of unknown two-qubit entanglement  

Science Conference Proceedings (OSTI)

We propose a scheme for both distilling and quantifying entanglement, applicable to individual copies of an arbitrary unknown two-qubit state. It is realized in a usual two-qubit interferometry with local filtering. Proper filtering operation for the maximal distillation of the state is achieved by erasing single-qubit interference, and then the concurrence of the state is determined directly from the visibilities of two-qubit interference. We compare the scheme with full state tomography.

Larger savings, as much as 80%, may be obtained by using a direct vapor recompression (VRC) heat pump instead of the conventional column operation with a steam heated reboiler. A main criterion of the suitability of a distillation for VRC is a low temperature difference across the column. VRC uses hot compressed overhead vapors, instead of steam, to heat the reboiler. Cost savings are highest when the pressure ratio for the compressor is low. The pressure ratio depends on the boiling point difference of top and bottom products, the reboiler-condenser driving force temperature and the column pressure drop. Structured packing has a low pressure drop; thus increasing the savings obtained with VRC - for retrofits or new columns - and increasing the range of applications where VRC is suitable for distillations. For low pressure distillation application, a column with a small pressure drop is especially important. An example of a vacuum distillation which is made suitable for VRC with use of structured packing is separation of styrene and ethyl benzene. "

Steam distillation effect and oil quality change during steam injection  

SciTech Connect

Steam distillation is an important mechanism which reduces residual oil saturation during steam injection. It may be the main recovery mechanism in steamflooding of light oil reservoirs. As light components are distilled the residual (initial) oil, the residuum becomes heavier. Mixing the distilled components with the initial oil results in a lighter produced oil. A general method has been developed to compute steam distillation yield and to quantify oil quality changes during steam injection. The quantitative results are specific because the California crude data bank was used. But general principles were followed and calculations were based on information extracted from the DOE crude oil assay data bank. It was found that steam distillation data from the literature can be correlated with the steam distillation yield obtained from the DOE crude oil assays. The common basis for comparison was the equivalent normal boiling point. Blending of distilled components with the initial oil results in API gravity changes similar to those observed in several laboratory and field operations.

Many copies may be required for entanglement distillation  

E-Print Network (OSTI)

A mixed quantum state ? shared between two parties is said to be distillable if, by means of a protocol involving only local quantum operations and classical communication, the two parties can transform some number of copies of ? into a single shared pair of qubits having high fidelity with the maximally entangled state |? + ? = (|00 ? + |11?) / ? 2. In this paper it is proved that there exist states that are distillable, but for which an arbitrarily large number of copies is required before any distillation procedure can produce a shared pair of qubits with even a small amount of entanglement. Specifically, for every positive integer n there exists a state ? that is distillable, but given n or fewer copies of ? every distillation procedure outputting a single shared pair of qubits will output those qubits in a separable (i.e., unentangled) state. Essentially all previous examples of states proved to be distillable were such that some distillation procedure could output an entangled pair of qubits given a single copy of the state in question. 1

Distillation by repeated measurements: Continuous spectrum case  

Science Conference Proceedings (OSTI)

Repeated measurements on one part of a bipartite system strongly affect the other part that is not measured, the dynamics of which is regulated by an effective contracted evolution operator. When the spectrum of this operator is discrete, the nonmeasured system is driven into a pure state, irrespective of the initial state, provided that the spectrum satisfies certain conditions. We show here that, even in the case of continuous spectrum, an effective distillation can occur under rather general conditions. We confirm it by applying our formalism to a simple model.

GENERATING CAPACITY  

E-Print Network (OSTI)

Evidence from the U.S. and some other countries indicates that organized wholesale markets for electrical energy and operating reserves do not provide adequate incentives to stimulate the proper quantity or mix of generating capacity consistent with mandatory reliability criteria. A large part of the problem can be associated with the failure of wholesale spot market prices for energy and operating reserves to rise to high enough levels during periods when generating capacity is fully utilized. Reforms to wholesale energy markets, the introduction of well-design forward capacity markets, and symmetrical treatment of demand response and generating capacity resources to respond to market and institutional imperfections are discussed. This policy reform program is compatible with improving the efficiency of spot wholesale electricity markets, the continued evolution of competitive retail markets, and restores incentives for efficient investment in generating capacity consistent with operating reliability criteria applied by system operators. It also responds to investment disincentives that have been associated with volatility in wholesale energy prices, limited hedging opportunities and to concerns about regulatory opportunism. 1

Distillation process using microchannel technology  

Science Conference Proceedings (OSTI)

The disclosed invention relates to a distillation process for separating two or more components having different volatilities from a liquid mixture containing the components. The process employs microchannel technology for effecting the distillation and is particularly suitable for conducting difficult separations, such as the separation of ethane from ethylene, wherein the individual components are characterized by having volatilities that are very close to one another.

Absorptive Recycle of Distillation Waste Heat  

E-Print Network (OSTI)

When the heat source available to a distillation process is at a significantly higher temperature than the reboiler temperature, there is unused availability (ability to perform work) in the heat supplied to the reboiler. Similarly, if the reflux condenser operates above ambient temperature, the rejected heat also contains unused availability. By incorporating an absorption heat pump (AHP) into the distillation process, these sources of unused availability can be tapped so as to recycle (and hence, conserve) up to 50% of the required distillation energy. In contrast to compressor driven heat pumps, this savings is accomplished without need for a separate substantial input of mechanical power. A different AHP configuration is used depending on whether the excess availability is in the source heat or reject heat. In the excessive source temperature case, the higher temperature source heat is applied to the AHP, which then supplies the total reboiler requirement and recycles half the reject heat, with the remainder being rejected conventionally. In the excessive reject temperature case, all the reject heat is supplied to a reverse absorption heat pump (HAHP) which recycles half to reboiler temperature while reducing the remainder to ambient temperature.

Isotropic non-locality cannot be distilled  

E-Print Network (OSTI)

We investigate non-locality distillation protocols for isotropic correlations. These correlations are the hardest instances which respect to distillability and only partial results are known about their behaviour under non-locality distillation protocols. We completely resolve this issue by proving that non-locality distillation is impossible for all non-local isotropic correlations.

Ethanol production by vapor compression distillation  

DOE Green Energy (OSTI)

The goal of this project is to develop and demonstrate a one gallon per hour vapor compression distillation unit for fuel ethanol production that can be profitably manufactured and economically operated by individual family units. Vapor compression distillation is already an industrially accepted process and this project's goal is to demonstrate that it can be done economically on a small scale. Theoretically, the process is independent of absolute pressure. It is only necessary that the condenser be at higher pressure than the evaporator. By reducing the entire process to a pressure of approximately 0.1 atmosphere, the evaporation and condensation can occur at near ambient temperature. Even though this approach requires a vacuum pump, and thus will not represent the final cost effective design, it does not require preheaters, high temperature materials, or as much insulation as if it were to operate a near ambient pressure. Therefore, the operation of the ambient temperature unit constitutes the first phase of this project. Presently, the ambient temperature unit is fully assembled and has begun testing. So far it has successfully separated ethanol from a nine to one diluted input solution. However the production rate has been very low.

U.S. Distillate Market  

Gasoline and Diesel Fuel Update (EIA)

diesel and heating fuel prices diesel and heating fuel prices surged. The largest increases occurred in the distillate-based fuels (heating oil and diesel) in the Northeast. The main factors driving up these prices were low stocks leading into January, followed by a bout of severe weather that impacted both supply and demand. Warmer weather and the arrival of new supply, mainly imports, relieved the supply/demand imbalance and brought prices back down. The spike is now behind us, but high crude prices are keeping prices above year-ago levels. The low stock situation that set the stage for the distillate price spike was not unique to the United States, Low stocks exist worldwide and are not limited to distillate. The low stock situation stems from what is happening in the crude oil markets. A crude oil supply shortage drove crude

Optimal protocols for nonlocality distillation  

Science Conference Proceedings (OSTI)

Forster et al. recently showed that weak nonlocality can be amplified by giving the first protocol that distills a class of nonlocal boxes (NLBs) [Phys. Rev. Lett. 102, 120401 (2009)] We first show that their protocol is optimal among all nonadaptive protocols. We next consider adaptive protocols. We show that the depth-2 protocol of Allcock et al. [Phys. Rev. A 80, 062107 (2009)] performs better than previously known adaptive depth-2 protocols for all symmetric NLBs. We present a depth-3 protocol that extends the known region of distillable NLBs. We give examples of NLBs for which each of the Forster et al., the Allcock et al., and our protocols perform best. The understanding we develop is that there is no single optimal protocol for NLB distillation. The choice of which protocol to use depends on the noise parameters for the NLB.

Refiner/marketer targets production of transportation fuels and distillates  

Science Conference Proceedings (OSTI)

Citgo Petroleum Corp., the wholly owned subsidiary of Petroleos de Venezuela, S.A. (PDVSA), the Venezuelan national oil company, owns two gasoline producing refineries, a 305,000-b/d system in Lake Charles, La., and a 130,000-b/d facility in Corpus Christi, Texas. Each is considered a deep conversion facility capable of converting heavy, sour crudes into a high percentage of transportation fuels and distillates. Two smaller refineries, one in Paulsboro, N.J., and one in Savannah, GA., have the capacity to process 40,000 b/d and 28,000 b/d of crude, respectively, for asphalt products. In the past two years, Citgo`s light oils refineries operated safely and reliably with a minimum of unscheduled shutdowns. An ongoing emphasis to increase reliability has resulted in extended run lengths at the refineries. Citgo has invested $314 million at its facilities in 1995, much of this toward environmental and regulatory projects, such as the new waste water treatment unit at the Lake Charles refinery. Over the next few years, Citgo expects to complete $1.5 billion in capital spending for major processing units such as a 60,000-b/d FCC feed hydrotreater unit at the Lake Charles refinery and crude expansion at the Corpus Christi refinery. Product exchanges and expanded transport agreements are allowing Citgo to extend its marketing reach.

Non-Locality Distillation is Impossible for Isotropic Quantum Systems  

E-Print Network (OSTI)

Non-locality is a powerful resource for various communication and information theoretic tasks, e.g., to establish a secret key between two parties, or to reduce the communication complexity of distributed computing. Typically, the more non-local a system is, the more useful it is as a resource for such tasks. We address the issue of non-locality distillation, i.e., whether it is possible to create a strongly non-local system by local operations on several weakly non-local ones. More specifically, we consider a setting where non-local systems can be realized via measurements on underlying shared quantum states. The hardest instances for non-locality distillation are the isotropic quantum systems: if a certain isotropic system can be distilled, then all systems of the same non-locality can be distilled as well. The main result of this paper is that non-locality cannot be distilled from such isotropic quantum systems. Our results are based on the theory of cross norms defined over the tensor product of certain Banach spaces. In particular, we introduce a single-parameter family of cross norms, which is used to construct a hierarchy of convex sets that are closed under local operations. This hierarchy interpolates between the set of local systems and an approximation to the set of quantum systems.

Bound States for Magic State Distillation in Fault-Tolerant Quantum Computation  

E-Print Network (OSTI)

Magic state distillation is an important primitive in fault-tolerant quantum computation. The magic states are pure non-stabilizer states which can be distilled from certain mixed non-stabilizer states via Clifford group operations alone. Because of the Gottesman-Knill theorem, mixtures of Pauli eigenstates are not expected to be magic state distillable, but it has been an open question whether all mixed states outside this set may be distilled. In this Letter we show that, when resources are finitely limited, non-distillable states exist outside the stabilizer octahedron. In analogy with the bound entangled states, which arise in entanglement theory, we call such states bound states for magic state distillation.

Unifying classical and quantum key distillation  

E-Print Network (OSTI)

Assume that two distant parties, Alice and Bob, as well as an adversary, Eve, have access to (quantum) systems prepared jointly according to a tripartite state. In addition, Alice and Bob can use local operations and authenticated public classical communication. Their goal is to establish a key which is unknown to Eve. We initiate the study of this scenario as a unification of two standard scenarios: (i) key distillation (agreement) from classical correlations and (ii) key distillation from pure tripartite quantum states. Firstly, we obtain generalisations of fundamental results related to scenarios (i) and (ii), including upper bounds on the key rate. Moreover, based on an embedding of classical distributions into quantum states, we are able to find new connections between protocols and quantities in the standard scenarios (i) and (ii). Secondly, we study specific properties of key distillation protocols. In particular, we show that every protocol that makes use of pre-shared key can be transformed into an equally efficient protocol which needs no pre-shared key. This result is of practical significance as it applies to quantum key distribution (QKD) protocols, but it also implies that the key rate cannot be locked with information on Eve's side. Finally, we exhibit an arbitrarily large separation between the key rate in the standard setting where Eve is equipped with quantum memory and the key rate in a setting where Eve is only given classical memory. This shows that assumptions on the nature of Eve's memory are important in order to determine the correct security threshold in QKD.

Intermediate Vapor Expansion Distillation and Nested Enrichment Cascade Distillation  

E-Print Network (OSTI)

Although it is known that incorporating an intermediate reboiler or reflux condenser in a distillation column will improve column efficiency by 15 to 100%, there has been little use of this technique to date." Intermediate vapor compression heat pumping was recently introduced as one practical means of achieving this benefit. Introduced in this paper are two new means having added advantages over compression: intermediate vapor expansion heat pumping, and nested enrichment cascades. In both cases the efficiency advantage is obtained without requiring import of shaft work. With intermediate vapor expansion, the expander is more efficient and less costly than the compressor which achieves comparable improvement in distillation efficiency. With the "nested enrichment" technique, the increased efficiency is obtained without requiring either compressors or expanders.

Improved magic states distillation for quantum universality  

E-Print Network (OSTI)

Given stabilizer operations and the ability to repeatedly prepare a single-qubit mixed state rho, can we do universal quantum computation? As motivation for this question, "magic state" distillation procedures can reduce the general fault-tolerance problem to that of performing fault-tolerant stabilizer circuits. We improve the procedures of Bravyi and Kitaev in the Hadamard "magic" direction of the Bloch sphere to achieve a sharp threshold between those rho allowing universal quantum computation, and those for which any calculation can be efficiently classically simulated. As a corollary, the ability to repeatedly prepare any pure state which is not a stabilizer state (e.g., any single-qubit pure state which is not a Pauli eigenstate), together with stabilizer operations, gives quantum universality. It remains open whether there is also a tight separation in the so-called T direction.

U.S. Distillate Market  

Gasoline and Diesel Fuel Update (EIA)

U.S. diesel and heating fuel U.S. diesel and heating fuel prices surged. The largest increases occurred in the distillate-based fuels (heating oil and diesel) in the Northeast. From January 17, New England residential heating oil prices rose over 78 cents per gallon to average $1.97 February 7; diesel increased 68 cents per gallon, averaging $2.12 February 7. Prices for both fuels began to fall back by February 14 as new supplies were arriving, and have continued to decline since. The main factors driving up these prices were low stocks leading into January, followed by a bout of severe weather that impacted both supply and demand. Demand: Cold weather increases core heating customer demand. In addition, it was reported that utilities were buying distillate both for peaking power and, along with industrial and commercial users, to

Draft environmental impact statement for the siting, construction, and operation of New Production Reactor capacity. Volume 2, Sections 1-6  

SciTech Connect

This (EIS) assesses the potential environmental impacts, both on a broad programmatic level and on a project-specific level, concerning a proposed action to provide new tritium production capacity to meet the nation`s nuclear defense requirements well into the 21st century. A capacity equivalent to that of about a 3,000-megawatt (thermal) heavy-water reactor was assumed as a reference basis for analysis in this EIS; this is the approximate capacity of the existing production reactors at DOE`s Savannah River Site. The EIS programmatic alternatives address Departmental decisions to be made on whether to build new production facilities, whether to build one or more complexes, what size production capacity to provide, and when to provide this capacity. Project-specific impacts for siting, constructing, and operating new production reactor capacity are assessed for three alternative sites: the Hanford Site near Richland, Washington; the Idaho National Engineering Laboratory near Idaho Falls, Idaho; and the Savannah River Site. For each site, the impacts of three reactor technologies (and supporting facilities) are assessed: a heavy-water reactor, a light-water reactor, and a modular high-temperature gas-cooled reactor. Impacts of the no-action alternative also are assessed. The EIS evaluates impacts related to air quality; noise levels; surface water, groundwater, and wetlands; land use; recreation; visual environment; biotic resources; historical, archaeological, and cultural resources; socioeconomics; transportation; waste management; and human health and safety. The EIS describes in detail the potential radioactive releases from new production reactors and support facilities and assesses the potential doses to workers and the general public. This volume contains the analysis of programmatic alternatives, project alternatives, affected environment of alternative sites, environmental consequences, and environmental regulations and permit requirements.

The Scaleup of Structured Packing from Distillation Pilot Plant Testing to Commercial Application  

E-Print Network (OSTI)

Structured packing is being utilized more and more in the process industry for increased efficiency, greater capacity, and energy savings in distillation columns. Pilot plant testing of the actual chemical system using commercially available structured packing is invaluable, but years of experience in pilot plant testing have shown that scaleup to successful commercial designs is a complicated process. In this paper an actual case history is cited as an example of the problems and benefits of conducting pilot plant tests which set the commercial design bases for a distillation train. The actual pilot plant testing involved a different structured packing type and blocked out operations to simulate a large number of theoretical stages. The pilot plant results verified the thermodynamic data to a high confidence level. As a result, the initial commercial installation of structured packing was started immediately. The actual installation and the startup are covered with a discussion of the energy savings and quality improvement which were obtained by replacing trays with the packing. Another case of retrofit testing in the new Koch Development Pilot Plant is discussed indicating other areas for attention to detail.

Distributive Distillation Enabled by Microchannel Process Technology  

SciTech Connect

The application of microchannel technology for distributive distillation was studied to achieve the Grand Challenge goals of 25% energy savings and 10% return on investment. In Task 1, a detailed study was conducted and two distillation systems were identified that would meet the Grand Challenge goals if the microchannel distillation technology was used. Material and heat balance calculations were performed to develop process flow sheet designs for the two distillation systems in Task 2. The process designs were focused on two methods of integrating the microchannel technology â?? 1) Integrating microchannel distillation to an existing conventional column, 2) Microchannel distillation for new plants. A design concept for a modular microchannel distillation unit was developed in Task 3. In Task 4, Ultrasonic Additive Machining (UAM) was evaluated as a manufacturing method for microchannel distillation units. However, it was found that a significant development work would be required to develop process parameters to use UAM for commercial distillation manufacturing. Two alternate manufacturing methods were explored. Both manufacturing approaches were experimentally tested to confirm their validity. The conceptual design of the microchannel distillation unit (Task 3) was combined with the manufacturing methods developed in Task 4 and flowsheet designs in Task 2 to estimate the cost of the microchannel distillation unit and this was compared to a conventional distillation column. The best results were for a methanol-water separation unit for the use in a biodiesel facility. For this application microchannel distillation was found to be more cost effective than conventional system and capable of meeting the DOE Grand Challenge performance requirements.

Catalytic dewaxing of middle distillates  

SciTech Connect

The fractionation and stripping equipment of a middle distillate catalytic dewaxing unit may be eliminated by integrating the catalytic dewaxing unit with a catalytic cracking unit. The light cycle oil sidestream from the cat cracker fractionator, bypasses the sidestream stripper and serves as the feed to the catalytic dewaxing unit. The dewaxed product is separated into a gasoline fraction which is recycled for fractionation in the cat cracker fractionator and a fuel oil fraction which is recycled to the cat cracker sidestream stripper for removal of light materials to produce a low pour fuel oil meeting product specifications.

Entanglement distillation from quasifree Fermions  

E-Print Network (OSTI)

We develop a scheme to distill entanglement from bipartite Fermionic systems in an arbitrary quasifree state. It can be applied if either one system containing infinite one-copy entanglement is available or if an arbitrary amount of equally prepared systems can be used. We show that the efficiency of the proposed scheme is in general very good and in some cases even optimal. Furthermore we apply it to Fermions hopping on an infinite lattice and demonstrate in this context that an efficient numerical analysis is possible for more then 10^6 lattice sites.

Conversion of carboxylate salts to carboxylic acids via reactive distillation  

E-Print Network (OSTI)

The purpose of this study is to convert carboxylate salts (e.g. calcium acetate, propionate, and butyrate) into carboxylic acids (e.g., acetic, propionic, and butyric acids). The carboxylate salts can be produced from wastes, such as paper fines, municipal solid wastes, sewage sludge, and industrial biosludge. Using a proprietary technology owned by Texas A&M University the wastes are first treated with lime to enhance reactivity. Then they are converted to calcium carboxylate salts using a mixed culture of microorganisms derived from cattle rumen or anaerobic waste treatment facilities. The paper fines and municipal solid waste provide energy, whereas the industrial biosludge and sewage sludge provide nutrients for the microorganisms. The calcium carboxylate salts are concentrated and reacted with a low-molecular-weight tertiary amine and carbon dioxide to precipitate calcium carbonate. In a distillation column, the low-molecular-weight amine carboxylate reacts with a high-molecular-weight tertiary amine allowing the low-molecular-weight amine to be recovered from the top of the column. The resulting high-molecular-weight amine carboxylate is converted to amine and carboxylic acid in a reactive distillation column. This project focuses on the conversion of the carboxylate salts produced via fermentation into their corresponding acids via reactive distillation. The primary objective is to determine the optimal operating conditions of the distillation. A secondary objective is to optimize the precipitation step in the recovery process.

Distillation and purification of symmetric entangled Gaussian states  

Science Conference Proceedings (OSTI)

We propose an entanglement distillation and purification scheme for symmetric two-mode entangled Gaussian states that allows to asymptotically extract a pure entangled Gaussian state from any input entangled symmetric Gaussian state. The proposed scheme is a modified and extended version of the entanglement distillation protocol originally developed by Browne et al. [Phys. Rev. A 67, 062320 (2003)]. A key feature of the present protocol is that it utilizes a two-copy degaussification procedure that involves a Mach-Zehnder interferometer with single-mode non-Gaussian filters inserted in its two arms. The required non-Gaussian filtering operations can be implemented by coherently combining two sequences of single-photon addition and subtraction operations.

On the distillation and purification of phase-diffused squeezed states  

E-Print Network (OSTI)

Recently it was discovered that non-Gaussian decoherence processes, such as phase-diffusion, can be counteracted by purification and distillation protocols that are solely built on Gaussian operations. Here, we make use of this experimentally highly accessible regime, and provide a detailed experimental and theoretical analysis of several strategies for purification/distillation protocols on phase-diffused squeezed states. Our results provide valuable information for the optimization of such protocols with respect to the choice of the trigger quadrature, the trigger threshold value and the probability of generating a distilled state.

Lower bound on concurrence and distillation for arbitrary-dimensional bipartite quantum states  

Science Conference Proceedings (OSTI)

We present a lower bound of concurrence for arbitrary-dimensional bipartite quantum states. This lower bound may be used to improve all the known lower bounds of concurrence. Moreover, the lower bound gives rise to an operational sufficient criterion of distillability of quantum entanglement. The significance of our result is illustrated by quantitative evaluation of entanglement for entangled states that fail to be identified by the usual concurrence estimation method and by showing the distillability of mixed states that cannot be recognized by other distillability criteria.

U.S. Distillate Inventory Outlook  

Gasoline and Diesel Fuel Update (EIA)

7 7 Notes: Total distillate stocks rose only marginally in November, to about 117 million barrels from about 115 million barrels at the end of October. The "normal" or average inventory level at end November is 146 million barrels. Thus, by the end of November, instead of seeing an improvement, US distillate inventories were 30 million barrels less than normal rather than the 26 million barrels less as of the end of October, indicating greater tightness in markets for heating oil and diesel fuel. If the currently depressed level of distillate stocks continues, the result could be strong upward pressure on prices for the distillate fuels through the winter. In fact, the tightness in distillate markets, particularly in the Northeast, has worsened and left the heating oil market more vulnerable

GeneDistiller—Distilling Candidate Genes from Linkage Intervals  

E-Print Network (OSTI)

Background: Linkage studies often yield intervals containing several hundred positional candidate genes. Different manual or automatic approaches exist for the determination of the gene most likely to cause the disease. While the manual search is very flexible and takes advantage of the researchers ’ background knowledge and intuition, it may be very cumbersome to collect and study the relevant data. Automatic solutions on the other hand usually focus on certain models, remain ‘‘black boxes’ ’ and do not offer the same degree of flexibility. Methodology: We have developed a web-based application that combines the advantages of both approaches. Information from various data sources such as gene-phenotype associations, gene expression patterns and protein-protein interactions was integrated into a central database. Researchers can select which information for the genes within a candidate interval or for single genes shall be displayed. Genes can also interactively be filtered, sorted and prioritised according to criteria derived from the background knowledge and preconception of the disease under scrutiny. Conclusions: GeneDistiller provides knowledge-driven, fully interactive and intuitive access to multiple data sources. It displays maximum relevant information, while saving the user from drowning in the flood of data. A typical query takes less than two seconds, thus allowing an interactive and explorative approach to the hunt for the candidate gene.

Distillability and PPT entanglement of low-rank quantum states  

E-Print Network (OSTI)

It is known that he bipartite quantum states, with rank strictly smaller than the maximum of the ranks of its two reduced states, are distillable by local operations and classical communication. Our first main result is that this is also true for NPT states with rank equal to this maximum. (A state is PPT if the partial transpose of its density matrix is positive semidefinite, and otherwise it is NPT.) This was conjectured first in 1999 in the special case when the two local ranks are equal. Our second main result provides a complete solution of the separability problem for bipartite states of rank 4. Namely, we show that such a state is separable if and only if it is PPT and its range contains at least one product state. We also prove that the so called checkerboard states are distillable if and only if they are NPT.

On two-distillable Werner states  

E-Print Network (OSTI)

We consider bipartite mixed states in a d x d quantum system with d at least 3. We say that such a state is PPT if its partial transpose is positive semidefinite, and otherwise that it is NPT. The well-known Werner states are partitioned into three types: a) the separable states (same as the PPT states), b) the 1-distillable states (necessarily NPT), and c) the NPT states which are not 1-distillable. We give several different formulations and provide further evidence for validity of the conjecture that the type c) Werner states are not 2-distillable.

Distillate and Spot Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: This slide shows the strong influence crude oil prices have on retail distillate prices. The price for distillate fuel oil tracks the crude price increases seen in 1996 and the subsequent fall in 1997 and 1998. Distillate prices have also followed crude oil prices up since the beginning of 1999. Actual data show heating oil prices on the East Coast in June at $1.20 per gallon, up 39 cents over last June. However, if heating oil prices are following diesel, they may be up another 5 cents in August. That would put heating oil prices about 40 cents over last August prices. Crude oil prices are only up about 25 cents in August over year ago levels. The extra 15 cents represents improved refiner margins due in part to the very low distillate inventory level.

Energy Recovery in Industrial Distillation Processes  

E-Print Network (OSTI)

Distillation processes are energy intensive separation processes which present attractive opportunities for energy conservation. Through the use of multistage vapor recompression, heat which is normally unavailable can be delivered at suitably high temperatures resulting in significant energy savings. The distillation process will be reviewed as it relates to both vapor recompression and heat pumping techniques and case study examples of these energy recovery methods will be discussed.

Multipartite secret key distillation and bound entanglement  

Science Conference Proceedings (OSTI)

Recently it has been shown that quantum cryptography beyond pure entanglement distillation is possible and a paradigm for the associated protocols has been established. Here we systematically generalize the whole paradigm to the multipartite scenario. We provide constructions of new classes of multipartite bound entangled states, i.e., those with underlying twisted Greenberger-Horne-Zeilinger (GHZ) structure and nonzero distillable cryptographic key. We quantitatively estimate the key from below with the help of the privacy squeezing technique.

Entangling and disentangling capacities are the key manifestation of the nonlocal content of a quantum operation. A lot of effort has been put recently into investigating (dis)entangling capacities of unitary operations, but very little is known about capacities of non-unitary operations. Here we investigate (dis)entangling capacities of unital CPTP maps acting on two qubits.

1 DISTILLERS BY-PRODUCTS AND CORN STOVER AS FUELS FOR ETHANOL PLANTS  

E-Print Network (OSTI)

Abstract. Dry-grind ethanol plants have the potential to reduce their operating costs and improve their net energy balances by using biomass as the source of process heat and electricity. We utilized ASPEN PLUS software to model various technology bundles of equipment, fuels and operating activities that are capable of supplying energy and satisfying emissions requirements for dry-grind ethanol plants of 50 and 100 million gallons per year capacity using corn stover, distillers dried grains and solubles (DDGS), or a mixture of corn stover and “syrup ” (the solubles portion of DDGS). In addition to their own requirements, plants producing 50 and 100 million gallons of ethanol are capable of supplying 5-7 or 10-14 MegaWatts of electricity to the grid, respectively. Economic analysis showed favorable rates of return for biomass alternatives compared to conventional plants using natural gas and purchased electricity over a range of conditions. The mixture of corn stover and syrup provided the highest rates of return in general. Factors favoring biomass included a higher premium for low carbon footprint ethanol, higher natural gas prices, lower DDGS prices, lower ethanol

Distillation: Energy Savings and Other Benefits From the Use of High Efficiency Packings  

E-Print Network (OSTI)

A great deal of attention has been focused lately on the use of high-efficiency packings for distillation applications. This paper discusses benefits that can be derived from the use of these devices. In particular, the reduction in energy requirements for a given separation is addressed for both new and retrofit applications. Pressure loss and product decomposition are also considered, and the basis for an alternative analysis is established. An example is shown in which an existing distillation tray column is retrofitted with a high-efficiency packing. The process advantages achieved, including energy savings, are discussed, as well as the factors governing the selection of the packing. The current limitations on design models for high-efficiency packings with respect to mass transfer efficiency, pressure drop, and capacity in distillation are mentioned briefly. Finally, the applications of these devices to alternative technologies such as liquid-liquid extraction are discussed.

PILOT-SCALE REMOVAL OF FLUORIDE FROM LEGACY PLUTONIUM MATERIALS USING VACUUM SALT DISTILLATION  

Science Conference Proceedings (OSTI)

Between September 2009 and January 2011, the Savannah River National Laboratory (SRNL) and HB-Line designed, developed, tested, and successfully deployed a system for the distillation of chloride salts. In 2011, SRNL adapted the technology for the removal of fluoride from fluoride-bearing salts. The method involved an in situ reaction between potassium hydroxide (KOH) and the fluoride salt to yield potassium fluoride (KF) and the corresponding oxide. The KF and excess KOH can be distilled below 1000{deg}C using vacuum salt distillation (VSD). The apparatus for vacuum distillation contains a zone heated by a furnace and a zone actively cooled using either recirculated water or compressed air. During a vacuum distillation operation, a sample boat containing the feed material is placed into the apparatus while it is cool, and the system is sealed. The system is evacuated using a vacuum pump. Once a sufficient vacuum is attaned, heating begins. Volatile salts distill from the heated zone to the cooled zone where they condense, leaving behind the non-volatile material in the feed boat. Studies discussed in this report were performed involving the use of non-radioactive simulants in small-scale and pilot-scale systems as well as radioactive testing of a small-scale system with plutonium-bearing materials. Aspects of interest include removable liner design considerations, boat materials, in-line moisture absorption, and salt deposition.

Local purity distillation with bounded classical communication  

E-Print Network (OSTI)

Local pure states are an important resource for quantum computing. The problem of distilling local pure states from mixed ones can be cast in an information theoretic paradigm. The bipartite version of this problem where local purity must be distilled from an arbitrary quantum state shared between two parties, Alice and Bob, is closely related to the problem of separating quantum and classical correlations in the state and in particular, to a measure of classical correlations called the one-way distillable common randomness. In Phys. Rev. A 71, 062303 (2005), the optimal rate of local purity distillation is derived when many copies of a bipartite quantum state are shared between Alice and Bob, and the parties are allowed unlimited use of a unidirectional dephasing channel. In the present paper, we extend this result to the setting in which the use of the channel is bounded. We demonstrate that in the case of a classical-quantum system, the expression for the local purity distilled is efficiently computable and provide examples with their tradeoff curves.

Spot Distillate & Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: Retail distillate prices follow the spot distillate markets, and crude oil prices have been the main driver behind distillate spot price increases until recently. Crude oil rose about 36 cents per gallon from its low point in mid February 1999 to the middle of January 2000. Over this same time period, New York Harbor spot heating oil had risen about 42 cents per gallon, reflecting both the crude price rise and a return to a more usual seasonal spread over the price of crude oil. The week ending January 21, heating oil spot prices in the Northeast spiked dramatically to record levels, closing on Friday at $1.26 per gallon -- up 50 cents from the prior week. Gulf Coast prices were not spiking, but were probably pulled slightly higher as the New York Harbor market began to

Forward capacity market CONEfusion  

Science Conference Proceedings (OSTI)

In ISO New England and PJM it was assumed that sponsors of new capacity projects would offer them into the newly established forward centralized capacity markets at prices based on their levelized net cost of new entry, or ''Net CONE.'' But the FCCMs have not operated in the way their proponents had expected. To clear up the CONEfusion, FCCM designs should be reconsidered to adapt them to the changing circumstances and to be grounded in realistic expectations of market conduct. (author)

Entangling capacity with local ancilla  

E-Print Network (OSTI)

We investigate the entangling capacity of a dynamical operation with access to local ancilla. A comparison is made between the entangling capacity with and without the assistance of prior entanglement. An analytic solution is found for the log-negativity entangling capacity of two-qubit gates, which equals the entanglement of the Choi matrix isomorphic to the unitary operator. Surprisingly, the availability of prior entanglement does not affect this result; a property we call resource independence of the entangling capacity. We prove several useful upper-bounds on the entangling capacity that hold for general qudit dynamical operations, and for a whole family of entanglement measures including log-negativity and log-robustness. The log-robustness entangling capacity is shown to be resource independent for general dynamics. We provide numerical results supporting a conjecture that the log-negativity entangling capacity is resource independence for all two-qudit unitaries.

Radian Corporation, under contract to the Electric Power Research Institute, has recently completed a study of the potential range of application for retrofitting electric driven heat pumps to existing distillation columns. A computerized evaluation program was developed, consisting of simulation, cost estimation, and economics analysis. The simulations were done using the PROCESS simulation package, while the cost and economics analysis routines were developed by Radian. This paper summarizes the results of the evaluations of retrofits to four generic distillation processes. In addition, the bases of the evaluation programs and the results of several peripheral tasks are described briefly.

Distillate Problem Likely to be Resolved Soon, But Recurrence Possible  

Gasoline and Diesel Fuel Update (EIA)

2 of 15 2 of 15 Notes: The current high prices in the Northeast should prompt increased production. Regional stocks will shift to areas of highest need, production from East Coast and Gulf Coast refineries will increase (capacity is available as the utilization indicates), and if the problem persists, imports from Europe might be drawn to U.S. But there are several caveats as to the quickness of the price response: Colder weather would quickly use up additional supply moving into the area, postponing relief for the price spike Further refinery problems and/or long delays in current East Coast refinery recoveries would slow new supply from arriving. As of January 31, distillate spot prices had dropped back to 82 cents, which still provides attractive refinery margins, but illustrates

Distillate Stocks Are Important Part of Northeast Winter Supply  

Gasoline and Diesel Fuel Update (EIA)

The weather alone was not enough to cause the price spike. The low The weather alone was not enough to cause the price spike. The low stocks left the area vulnerable to sudden changes in the market, such as the weather change. Why do stocks matter in the Northeast? Stocks are normally an important part of PADD 1 winter distillate supply. Over the last 5 years, PADD 1 stocks provided about 15% of supply during the peak winter months of January and February. They are the closest source of supply to the consumer. PADD 1 depends on about 60% of its supply from distant sources such as the Gulf Coast or imports, which can take several weeks to travel to the Northeast. Even product from East Coast refineries, if capacity is available, may take a week before it is produced and delivered to the regions needing new supply. Thus, stocks must be able

Distilling one-qubit magic states into Toffoli states

For certain quantum architectures and algorithms, most of the required resources are consumed during the distillation of one-qubit magic states for use in performing Toffoli gates. I show that the overhead for magic-state distillation can be reduced by merging distillation with the implementation of Toffoli gates. The resulting routine distills 8 one-qubit magic states directly to a Toffoli state, which can be used without further magic to perform a Toffoli gate.

Capacity is extremely dependent on infrastructure, traffic, and operating parameters. Therefore, an in-depth study of the main factors that influence railway capacity is performed on several Spanish railway infrastructures. The results show how the capacity varies according to factors such as train speed, commercial stops, train heterogeneity, distance between railway signals, and timetable robustness.

Investigation related to hydrogen isotopes separation by cryogenic distillation  

Science Conference Proceedings (OSTI)

Research conducted in the last fifty years has shown that one of the most efficient techniques of removing tritium from the heavy water used as moderator and coolant in CANDU reactors (as that operated at Cernavoda (Romania)) is hydrogen cryogenic distillation. Designing and implementing the concept of cryogenic distillation columns require experiments to be conducted as well as computer simulations. Particularly, computer simulations are of great importance when designing and evaluating the performances of a column or a series of columns. Experimental data collected from laboratory work will be used as input for computer simulations run at larger scale (for The Pilot Plant for Tritium and Deuterium Separation) in order to increase the confidence in the simulated results. Studies carried out were focused on the following: - Quantitative analyses of important parameters such as the number of theoretical plates, inlet area, reflux flow, flow-rates extraction, working pressure, etc. - Columns connected in series in such a way to fulfil the separation requirements. Experiments were carried out on a laboratory-scale installation to investigate the performance of contact elements with continuous packing. The packing was manufactured in our institute. (authors)

Development of a bench-scale metal distillation furnace  

SciTech Connect

Design of an inductively heated bench-scale distillation furnace (retort) capable of processing actinides is described. The apparatus consists of a vacuum/inert gas bell jar, a bell-jar lift, a nonwater-cooled induction coil, the induction tank circuit, and a series of components designed to contain the metal melts and vapors. The apparatus is located within a nitrogen glovebox and is designed to process plutonium-containing feeds. The electrical parameters of the induction coil and tank circuit necessary for design were determined by two different methods; one is based solely on calculated impedance values, and the other used high-frequency impedance measurements on a mock-up of the induction coil/susceptor arrangement. During the design state, the two methods of determining electrical parameters gave similar results. With the as-built system, the impedance meter did detect some efficiency loss to the metal bell jar and coil support that the calculational method did not predict. These losses were not significant enough to cause operating problems, and thus, both methods were shown to be adequate for the intended purpose. Zinc and magnesium were distilled, and uranium was melted in a successful series of shake-down runs.

Distillate Stocks Expected to Remain Low  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: When EIA's demand forecast is combined with its outlook for production and net imports, distillate stocks are projected to remain low for the rest of the year. - Stocks are beginning at very low levels. The September 1 distillate fuel stock level (112 million barrels) is nearly 20% less than last year, and about 15% below the 10 year average for end of August levels. - But stocks on the East Coast, at 39.8 million barrels, are 39% behind year-ago levels, and about a similar percentage below end-of-August 10-year average levels. Over the last 10 years, the average stock build from the end of August through the end of November has been about 10 million barrels. We are forecasting about a 12 million barrel build, which does not reach the normal band. Forecast stocks peak at the end of November at 127 million

Iterative entanglement distillation for finite resources  

E-Print Network (OSTI)

We discuss a specific entanglement distillation scheme under the constraint of finite samples of entangled qubit pairs. It is shown that an iterative process can be explicitly formulated. The average fidelity of this process can be enhanced by introducing conditional storing of entangled qubit pairs in each step of the iteration. We investigate the corresponding limitations on the size and the initial fidelity of the sample.

Distillation of vacuum entanglement to EPR pairs  

E-Print Network (OSTI)

It is shown that by means of local interactions between a quantized relativistic field and a pair of non-entangled atoms, entanglement can be extracted from the vacuum and delivered to the atoms. The resulting mixed state of the atoms can be further distilled to EPR pairs. Therefore, in principle, teleportation and other entanglement assisted quantum communication tasks can rely on the vacuum alone as a resource for entanglement.

Combustion of EDS mid-distillate and refined shale-oil residual fuel in a gas turbine with large single-combustion chamber  

DOE Green Energy (OSTI)

The test fuels included a coal derived mid distillate recycle liquid from the EDS coal liquefaction process, produced by Exxon, and a hydroprocessed residual Paraho shale oil fraction originating from a US Government sponsored program. A BBC (Brown Boveri Co.) type 9 fully equipped 35 MW capacity gas turbine, located at BBC's test facilities near Basel, Switzerland, was utilized. The objective of the combustion test was to establish whether these alternate fuels can be fired in large single combustor turbines without deleterious effects to the turbine or environment. Nitrogen in the shale oil was on the order of 0.4 wt% while the EDS distillate contained slightly less than 10 wt% hydrogen. The test program entailed the firing of 600 barrels of each test fuel at varying turbine loads and a comparison of the results with those from a base case petroleum diesel fuel. Fuel bound nitrogen was not found to contribute significantly to NO/sub x/ emissions in contrast to other work reported earlier in subscale gas turbine tests. Water injection at 0.6 to 0.7 water-fo-fuel mass ratios was effective in meeting EPA requirements for NO/sub x/ emissions from the diesel, shale and coal derived fuels at full turbine load. Low fuel hydrogen content did not cause any operational or emission problems. Combustor wall temperature, the major problem with low hydrogen fuels, rose only slightly within acceptable limits.

The attractor mechanism as a distillation procedure  

E-Print Network (OSTI)

In a recent paper it has been shown that for double extremal static spherically symmetric BPS black hole solutions in the STU model the well-known process of moduli stabilization at the horizon can be recast in a form of a distillation procedure of a three-qubit entangled state of GHZ-type. By studying the full flow in moduli space in this paper we investigate this distillation procedure in more detail. We introduce a three-qubit state with amplitudes depending on the conserved charges the warp factor, and the moduli. We show that for the recently discovered non-BPS solutions it is possible to see how the distillation procedure unfolds itself as we approach the horizon. For the non-BPS seed solutions at the asymptotically Minkowski region we are starting with a three-qubit state having seven nonequal nonvanishing amplitudes and finally at the horizon we get a GHZ state with merely four nonvanishing ones with equal magnitudes. The magnitude of the surviving nonvanishing amplitudes is proportional to the macroscopic black hole entropy. A systematic study of such attractor states shows that their properties reflect the structure of the fake superpotential. We also demonstrate that when starting with the very special values for the moduli corresponding to flat directions the uniform structure at the horizon deteriorates due to errors generalizing the usual bit flips acting on the qubits of the attractor states.

Science Conference Proceedings (OSTI)

The quantum states corresponding to a secret key are characterized using the so-called private states, where the key part consisting of a secret key is shielded by the additional systems. Based on the construction, it was shown that a secret key can be distilled from bound entangled states. In this work, I consider the shielded two-qubit states in a key-distillation scenario and derive the conditions under which a secret key can be distilled using the recurrence protocol or the two-way classical distillation, advantage distillation together with one-way postprocessing. From the security conditions, it is shown that a secret key can be distilled from bound entangled states in a much wider range. In addition, I consider the case that in which white noise is added to quantum states and show that the classical distillation protocol still works despite a certain amount of noise although the recurrence protocol does not.

Crude oil steam distillation in steam flooding. Final report  

SciTech Connect

Steam distillation yields of sixteen crude oils from various parts of the United States have been determined at a saturated steam pressure of 200 psig. Study made to investigate the effect of steam pressure (200 to 500 psig) on steam distillation yields indicates that the maximum yields of a crude oil may be obtained at 200 psig. At a steam distillation correlation factor (V/sub w//V/sub oi/) of 15, the determined steam distillation yields range from 12 to 56% of initial oil volume for the sixteen crude oils with gravity ranging from 12 to 40/sup 0/API. Regression analysis of experimental steam distillation yields shows that the boiling temperature (simulated distillation temperature) at 20% simulated distillation yield can predict the steam distillation yields reasonably well: the standard error ranges from 2.8 to 3.5% (in yield) for V/sub w//V/sub oi/ < 5 and from 3.5 to 4.5% for V/sub w//V/sub oi/ > 5. The oil viscosity (cs) at 100/sup 0/F can predict the steam distillation yields with standard error from 3.1 to 4.3%. The API gravity can predict the steam distillation yields with standard error from 4.4 to 5.7%. Characterization factor is an unsatisfactory correlation independent variable for correlation purpose.

High Performance Trays and Heat Exchangers in Heat Pumped Distillation Columns  

E-Print Network (OSTI)

Vapor recompression of distillation columns overheads, followed by subsequent condensation in the reboiler results in substantial operating cost savings compared to conventional steam driven reboiler systems. The use of high performance heat exchangers and distillation trays permits additional energy savings by lower reboiler temperature differences, and reduced reflux requirements for a fixed column height, due to closer tray spacings. This paper surveys the heat pump systems currently in operation using high performance UCC MD trays and High Flux tubing. Design considerations for high or low pressure level towers, with single or dual stage compression equipment are discussed, along with the various control methods. Factors affecting startup, part load, and off design operation of the equipment are also reviewed.

E-Print Network (OSTI)

In this paper we look at the challenges that improvements in energy efficiency of distillation systems presents the heat exchanger designer. We examine each type of exchanger in turn. Heat exchanger size is minimized if the temperature driving force is maximized. The design should therefore seek to minimize the temperature changes during phase change. So, streams that are being condensed are kept as hot as possible. Streams that are being vaporized are kept as cool as possible. With one noted exception, this also leads to maximization of the thermodynamic efficiency and maximizes the scope for use of these streams in integrated systems.

Surface code implementation of block code state distillation  

E-Print Network (OSTI)

State distillation is the process of taking a number of imperfect copies of a particular quantum state and producing fewer better copies. Until recently, the lowest overhead method of distilling states |A>=(|0>+e^{i\\pi/4}|1>)/\\sqrt{2} produced a single improved |A> state given 15 input copies. New block code state distillation methods can produce k improved |A> states given 3k+8 input copies, potentially significantly reducing the overhead associated with state distillation. We construct an explicit surface code implementation of block code state distillation and quantitatively compare the overhead of this approach to the old. We find that, using the best available techniques, for parameters of practical interest, block code state distillation does not always lead to lower overhead, and, when it does, the overhead reduction is typically less than a factor of three.

Tritium Isotope Separation Using Adsorption-Distillation Column  

Science Conference Proceedings (OSTI)

In order to miniaturize the height of a distillation tower for the detritiation of waste water from fusion reactors, two experiments were conducted: (1) liquid frontal chromatography of tritium water eluting through an adsorption column and (2) water distillation using a column packed with adsorbent particles. The height of the distillation tower depends on the height equivalent to a theoretical plate, HETP, and the equilibrium isotope separation factor, {alpha}{sub H-T}{sup equi}. The adsorption action improved not only HETP but also {alpha}{sub H-T}{sup equi}. Since the adsorption-distillation method proposed here can shorten the tower height with keeping advantages of the distillation, it may bring an excellent way for miniaturizing the distillation tower to detritiate a large amount of waste water from fusion reactors.

Iterative Entanglement Distillation: Approaching full Elimination of Decoherence  

E-Print Network (OSTI)

The distribution and processing of quantum entanglement form the basis of quantum communication and quantum computing. The realization of the two is difficult because quantum information inherently has a high susceptibility to decoherence, i.e. to uncontrollable information loss to the environment. For entanglement distribution, a proposed solution to this problem is capable of fully eliminating decoherence; namely iterative entanglement distillation. This approach builds on a large number of distillation steps each of which extracts a number of weakly decohered entangled states from a larger number of strongly decohered states. Here, for the first time, we experimentally demonstrate iterative distillation of entanglement. Already distilled entangled states were further improved in a second distillation step and also made available for subsequent steps.Our experiment displays the realization of the building blocks required for an entanglement distillation scheme that can fully eliminate decoherence.

Low Distillate Stocks Set Stage for Price Volatility  

Gasoline and Diesel Fuel Update (EIA)

Along with the recent rise in crude oil prices, low stocks of Along with the recent rise in crude oil prices, low stocks of distillate fuels left markets in a vulnerable position. As we went into our two biggest distillate demand months, January and February, U.S. distillate stocks were very low -- particularly on the East and Gulf Coasts. The East Coast is the primary heating oil region, and it depends heavily on production from the Gulf Coast as well. Distillate stocks in the U.S. and Europe were in surplus supply as recently as October, but distillate stocks did not build as they usually do during the late fall, and declined more sharply than usual in December. December stocks closed well below the normal range. The unusual drawdown, in contrast to the more normal building pattern, resulted in distillate inventory levels about 3 million barrels lower than the very low

A necessary and sufficient condition for 1-distillability is formulated in terms of decomposable positive maps. As an application we provide insight into why all states violating the reduction criterion map are distillable and demonstrate how to construct such maps in a systematic way. We establish a connection between a number of existing results, which leads to an elementary proof for the characterisation of distillability in terms of 2-positive maps.

Lett. 94, 160502 (2005)] as well as its multipartite and higher dimension generalizations always represent distillable entanglement. The corresponding lower bounds on distillable entanglement are provided. We also present a simple alternative proof that for any bipartite quantum state entanglement cost is an upper bound on distillable cryptographic key in bipartite scenario.

Distillation of GHZ states by selective information manipulation  

E-Print Network (OSTI)

Methods for distilling maximally entangled tripartite (GHZ) states from arbitrary entangled tripartite pure states are described. These techniques work for virtually any input state. Each technique has two stages which we call primary and secondary distillation. Primary distillation produces a GHZ state with some probability, so that when applied to an ensemble of systems, a certain percentage is discarded. Secondary distillation produces further GHZs from the discarded systems. These protocols are developed with the help of an approach to quantum information theory based on absolutely selective information, which has other potential applications.

Tomographic Quantum Cryptography: Equivalence of Quantum and Classical Key Distillation  

E-Print Network (OSTI)

The security of a cryptographic key that is generated by communication through a noisy quantum channel relies on the ability to distill a shorter secure key sequence from a longer insecure one. For an important class of protocols, which exploit tomographically complete measurements on entangled pairs of any dimension, we show that the noise threshold for classical advantage distillation is identical with the threshold for quantum entanglement distillation. As a consequence, the two distillation procedures are equivalent: neither offers a security advantage over the other.

Desalination Using Vapor-Compression Distillation  

E-Print Network (OSTI)

The ability to produce potable water economically is the primary purpose of seawater desalination research. Reverse osmosis (RO) and multi-stage flash (MSF) cost more than potable water produced from fresh water resources. As an alternative to RO and MSF, this research investigates a high-efficiency mechanical vapor-compression distillation system that employs an improved water flow arrangement. The incoming salt concentration was 0.15% salt for brackish water and 3.5% salt for seawater, whereas the outgoing salt concentration was 1.5% and 7%, respectively. Distillation was performed at 439 K (331oF) and 722 kPa (105 psia) for both brackish water feed and seawater feed. Water costs of the various conditions were calculated for brackish water and seawater feeds using optimum conditions considered as 25 and 20 stages, respectively. For brackish water at a temperature difference of 0.96 K (1.73oF), the energy requirement is 2.0 kWh/m3 (7.53 kWh/kgal). At this condition, the estimated water cost is $0.39/m3 ($1.48/kgal) achieved with 10,000,000 gal/day distillate, 30-year bond, 5% interest rate, and $0.05/kWh electricity. For seawater at a temperature difference of 0.44 K (0.80oF), the energy requirement is 3.97 kWh/m3 (15.0 kWh/kgal) and the estimated water cost is $0.61/m3 ($2.31/kgal). Greater efficiency of the vapor compression system is achieved by connecting multiple evaporators in series, rather than the traditional parallel arrangement. The efficiency results from the gradual increase of salinity in each stage of the series arrangement in comparison to parallel. Calculations using various temperature differences between boiling brine and condensing steam show the series arrangement has the greatest improvement at lower temperature differences. The following table shows the improvement of a series flow arrangement compared to parallel: ?T (K) Improvement (%)*1.111 2.222 3.333 15.21 10.80 8.37 * Incoming salt concentration: 3.5% Outgoing salt concentration: 7% Temperature: 450 K (350oF) Pressure: 928 kPa (120 psig) Stages: 4

Optimal entangling capacity of dynamical processes  

SciTech Connect

We investigate the entangling capacity of dynamical operations when provided with local ancilla. A comparison is made between the entangling capacity with and without the assistance of prior entanglement. An analytic solution is found for the log-negativity entangling capacity of two-qubit gates, which equals the entanglement of the Choi matrix isomorphic to the unitary operator. Surprisingly, the availability of prior entanglement does not affect this result, a property we call resource independence of the entangling capacity. We prove several useful upper bounds on the entangling capacity that hold for general qudit dynamical operations and for a whole family of entanglement monotones including log negativity and log robustness. The log-robustness entangling capacity is shown to be resource independent for general dynamics. We provide numerical results supporting a conjecture that the log-negativity entangling capacity is resource independent for all two-qudit unitary operators.

Crude Distillation Unit Heat Recovery Study  

E-Print Network (OSTI)

Baytown's Pipe Still 3 is a 95,000 barrel per day crude distillation unit. A comprehensive heat recovery and energy utilization study was done on Pipe Still 3 after a preliminary cursory study had indicated that an overall look at the total picture could produce much better results than a series of improvements done piecemeal. The study did meet its objective by identifying the maximum heat recovery that is technically and economically feasible. It showed a potential for dramatic improvement - a 39 percent reduction in fuel, plus a 43 percent increase in the quantity of process steam generated, equivalent to a 48 percent reduction in net energy consumed. Techniques employed included a Source/Sink Profile (which is described later); a combining of oil heating, steam generation, and air preheat to best advantage; and a computer program to design the required heat exchanger trains.

The robustness of magic state distillation against errors in Clifford gates  

E-Print Network (OSTI)

Quantum error correction and fault-tolerance have provided the possibility for large scale quantum computations without a detrimental loss of quantum information. A very natural class of gates for fault-tolerant quantum computation is the Clifford gate set and as such their usefulness for universal quantum computation is of great interest. Clifford group gates augmented by magic state preparation give the possibility of simulating universal quantum computation. However, experimentally one cannot expect to perfectly prepare magic states. Nonetheless, it has been shown that by repeatedly applying operations from the Clifford group and measurements in the Pauli basis, the fidelity of noisy prepared magic states can be increased arbitrarily close to a pure magic state [1]. We investigate the robustness of magic state distillation to perturbations of the initial states to arbitrary locations in the Bloch sphere due to noise. Additionally, we consider a depolarizing noise model on the quantum gates in the decoding section of the distillation protocol and demonstrate its effect on the convergence rate and threshold value. Finally, we establish that faulty magic state distillation is more efficient than fault-tolerance-assisted magic state distillation at low error rates due to the large overhead in the number of quantum gates and qubits required in a fault-tolerance architecture. The ability to perform magic state distillation with noisy gates leads us to conclude that this could be a realistic scheme for future small-scale quantum computing devices as fault-tolerance need only be used in the final steps of the protocol.

Model predictive control of a Kaibel distillation column  

E-Print Network (OSTI)

A Kaibel distillation column separates a feed into four products with significant lower energy consumption than a conventional sequence of binary columns. Optimal operation and control of such systems is an important task in order to obtain the potential energy savings. A laboratory column has been built at NTNU, Department of Chemical Engineering. At the time of the diploma work the laboratory column has unfortunately not been available for MPC experiments. In practical operation a control structure based on temperature measurements is chosen for the given case. This structure gives a four-by-four multivariable system. The candidate shall base his work on a model developed by Jens Strandberg. Tasks: 1. Describe the model and extend it to include an efficiency parameter describing insufficient mixing at stages 2. Describe a general linear MPC approach for the system 3. Analyze sensitivity of model errors 4. Evaluate alternative MPC approaches 5. Implement the MPC in MATLAB and illustrate the performance by simulations 6. Prepare a setup for connecting the MPC to the actual laboratory column

Measuring wind plant capacity value  

DOE Green Energy (OSTI)

Electric utility planners and wind energy researchers pose a common question: What is the capacity value of a wind plant? Tentative answers, which can be phrased in a variety of ways, are based on widely varying definitions and methods of calculation. From the utility`s point of view, a resource that has no capacity value also has a reduced economic value. Utility planners must be able to quantify the capacity value of a wind plant so that investment in conventional generating capacity can be potentially offset by the capacity value of the wind plant. Utility operations personnel must schedule its conventional resources to ensure adequate generation to meet load. Given a choice between two resources, one that can be counted on and the other that can`t, the utility will avoid the risky resource. This choice will be reflected in the price that the utility will pay for the capacity: higher capacity credits result in higher payments. This issue is therefore also important to the other side of the power purchase transaction -- the wind plant developer. Both the utility and the developer must accurately assess the capacity value of wind. This article summarizes and evaluates some common methods of evaluating capacity credit. During the new era of utility deregulation in the United States, it is clear that many changes will occur in both utility planning and operations. However, it is my judgement that the evaluation of capacity credit for wind plants will continue to play an important part in renewable energy development in the future.

Experimental results of hydrogen distillation at the low power cryogenic column for the production of deuterium depleted hydrogen  

Science Conference Proceedings (OSTI)

The Deuterium Removal Unit (DRU) has been designed and built at the Petersburg Nuclear Physics Inst. (PNPI) to produce isotopically pure hydrogen with deuterium content less than 1 ppm. The cryogenic distillation column of 2.2 cm inner diameter and 155 cm packing height is the main element of the DRU. Column performances at different hydrogen distillation operating modes have been measured. The height equivalent to theoretical plate (HETP) for the column is 2.2 cm and almost constant over a wide range of vapour flow rates. Deuterium depleted hydrogen with a deuterium content of less than 0.1 ppm was produced in required quantity. (authors)

APPLICATION OF VACUUM SALT DISTILLATION TECHNOLOGY FOR THE REMOVAL OF FLUORIDE  

SciTech Connect

Vacuum distillation of chloride salts from plutonium oxide (PuO{sub 2}) and simulant PuO{sub 2} has been previously demonstrated at Department of Energy (DOE) sites using kilogram quantities of chloride salt. The apparatus for vacuum distillation contains a zone heated using a furnace and a zone actively cooled using either recirculated water or compressed air. During a vacuum distillation operation, a sample boat containing the feed material is placed into the apparatus while it is cool, and the system is sealed. The system is evacuated using a vacuum pump. Once a sufficient vacuum is attained, heating begins. Volatile salts distill from the heated zone to the cooled zone where they condense, leaving behind the non-volatile materials in the feed boat. The application of vacuum salt distillation (VSD) is of interest to the HB-Line Facility and the MOX Fuel Fabrication Facility (MFFF) at the Savannah River Site (SRS). Both facilities are involved in efforts to disposition excess fissile materials. Many of these materials contain chloride and fluoride salt concentrations which make them unsuitable for dissolution without prior removal of the chloride and fluoride salts. Between September 2009 and January 2011, the Savannah River National Laboratory (SRNL) and HB-Line designed, developed, tested, and successfully deployed a system for the distillation of chloride salts. Subsequent efforts are attempting to adapt the technology for the removal of fluoride. Fluoride salts of interest are less-volatile than the corresponding chloride salts. Consequently, an alternate approach is required for the removal of fluoride without significantly increasing the operating temperature. HB-Line Engineering requested SRNL to evaluate and demonstrate the feasibility of an alternate approach using both non-radioactive simulants and plutonium-bearing materials. Whereas the earlier developments targeted the removal of sodium chloride (NaCl) and potassium chloride (KCl), the current activities are concerned with the removal of the halide ions associated with plutonium trifluoride (PuF{sub 3}), plutonium tetrafluoride (PuF{sub 4}), calcium fluoride (CaF{sub 2}), and calcium chloride (CaCl{sub 2}). This report discusses non-radioactive testing of small-scale and pilot-scale systems and radioactive testing of a small-scale system. Experiments focused on demonstrating the chemistry for halide removal and addressing the primary engineering questions associated with a change in the process chemistry.

Spot Distillate & Crude Oil Prices  

Gasoline and Diesel Fuel Update (EIA)

mid-January, 2000. WTI crude oil price rose about $17 per mid-January, 2000. WTI crude oil price rose about $17 per barrel or 40 cents per gallon from its low point in mid February 1999 to January 17, 2000. Over this same time period, New York Harbor spot heating oil had risen about 42 cents per gallon, reflecting both the crude price rise and the beginning of a return to a more usual seasonal spread over the price of crude oil. The week ending January 21, distillate spot prices in the Northeast spiked dramatically to record levels, closing on Friday at $1.26 per gallon -- up 50 cents from the prior week. Gulf Coast prices were not spiking, but were probably pulled higher as the New York Harbor market began to draw on product from other areas. They closed at 83 cents per gallon, an increase of 11 cents from the prior Friday. Crude oil had risen about 4 cents from

Distillate Supply/Demand Balance Reflected in Spreads  

Gasoline and Diesel Fuel Update (EIA)

4 4 Notes: The price spike that initiated the flood of distillate imports last winter can be easily seen in this chart. The distillate supply/demand balance influences the spread between spot distillate and spot crude oil prices. For example, when stocks are higher than normal, the spread will be lower than usual. This spread is the price incentive that encourages or discourages changes in supply. The January/February 2000 price spike was shorter than the one last winter, largely due to the timing. Since last winter's price spike occurred early in the season, it took some time before prices receded substantially. Currently, the distillate fuel refining spread (the difference between the spot heating oil price and the WTI price) is more "typical". But as was

Magic-state distillation with the four-qubit code  

E-Print Network (OSTI)

The distillation of magic states is an often-cited technique for enabling universal quantum computing once the error probability for a special subset of gates has been made negligible by other means. We present a routine for magic-state distillation that reduces the required overhead for a range of parameters of practical interest. Each iteration of the routine uses a four-qubit error-detecting code to distill the +1 eigenstate of the Hadamard gate at a cost of ten input states per two improved output states. Use of this routine in combination with the 15-to-1 distillation routine described by Bravyi and Kitaev allows for further improvements in overhead.

Kinetic Method for Hydrogen-Deuterium-Tritium Mixture Distillation Simulation  

Science Conference Proceedings (OSTI)

Simulation of hydrogen distillation plants requires mathematical procedures suitable for multicomponent systems. In most of the present-day simulation methods a distillation column is assumed to be composed of theoretical stages, or plates. However, in the case of a multicomponent mixture theoretical plate does not exist.An alternative kinetic method of simulation is depicted in the work. According to this method a system of mass-transfer differential equations is solved numerically. Mass-transfer coefficients are estimated with using experimental results and empirical equations.Developed method allows calculating the steady state of a distillation column as well as its any non-steady state when initial conditions are given. The results for steady states are compared with ones obtained via Thiele-Geddes theoretical stage technique and the necessity of using kinetic method is demonstrated. Examples of a column startup period and periodic distillation simulations are shown as well.

Future perspectives of using hollow fibers as structured packings in light hydrocarbon distillation  

SciTech Connect

Olefin and paraffin are the largest chemical commodities. Furthermore, they are major building blocks for the petrochemical industry. Each year, petroleum refining, consumes 4,500 TBtu/yr in separation energy, making it one of the most energy-intensive industries in the United States). Just considering liquefied petroleum gas (ethane/propane/butane) and olefins (ethylene and propylene) alone, the distillation energy consumption is about 400 TBtu/yr in the US. Since petroleum distillation is a mature technology, incremental improvements in column/tray design will only provide a few percent improvements in the performance. However, each percent saving in net energy use amounts to savings of 10 TBtu/yr and reduces CO{sub 2} emissions by 0.2 MTon/yr. In practice, distillation columns require 100 to 200 trays to achieve the desired separation. The height of a transfer unit (HTU) of conventional packings is typical in the range of 36-60 inch. Since 2006, we had explored using several non-selective membranes as the structured packings to replace the conventional packing materials used in propane and propylene distillation. We obtained the lowest HTU of < 8 inch for the hollow fiber column, which was >5 times shorter than that of the conventional packing materials. In 2008, we also investigated this type of packing materials in iso-/n-butane distillation. Because of a slightly larger relative volatility of iso-/n-butane than that of propane/propylene, a wider and a more stable operational range was obtained for the iso-/n-butane pair. However, all of the experiments were conducted on a small scale with flowrate of < 25 gram/min. Recently, we demonstrated this technology on a larger scale (<250 gram/min). Within the loading range of F-factor < 2.2 Pa{sup 0.5}, a pressure drop on the vapor side is below 50 mbar/m, which suggests that the pressure drop of hollow fibers packings is not an engineering barrier for the applications in distillations. The thermal stability study suggests that polypropylene hollow fibers are stable after a long time exposure to C{sub 2} - C{sub 4} mixtures. The effects of packing density on the separation efficiency will be discussed.

Fuel-blending stocks from the hydrotreatment of a distillate formed by direct coal liquefaction  

SciTech Connect

The direct liquefaction of coal in the iron-catalyzed Suplex process was evaluated as a technology complementary to Fischer-Tropsch synthesis. A distinguishing feature of the Suplex process, from other direct liquefaction processes, is the use of a combination of light- and heavy-oil fractions as the slurrying solvent. This results in a product slate with a small residue fraction, a distillate/naphtha mass ratio of 6, and a 65.8 mass % yield of liquid fuel product on a dry, ash-free coal basis. The densities of the resulting naphtha (C{sub 5}-200{sup o}C) and distillate (200-400{sup o}C) fractions from the hydroprocessing of the straight-run Suplex distillate fraction were high (0.86 and 1.04 kg/L, respectively). The aromaticity of the distillate fraction was found to be typical of coal liquefaction liquids, at 60-65%, with a Ramsbottom carbon residue content of 0.38 mass %. Hydrotreatment of the distillate fraction under severe conditions (200{sup o}C, 20.3 MPa, and 0.41 g{sub feed} h{sup -1} g{sub catalyst}{sup -1}) with a NiMo/Al{sub 2}O{sub 3} catalyst gave a product with a phenol content of {lt}1 ppm, a nitrogen content {lt}200 ppm, and a sulfur content {lt}25 ppm. The temperature was found to be the main factor affecting diesel fraction selectivity when operating at conditions of WHSV = 0.41 g{sub feed} h{sup -1} g{sub catalyst}{sup -1} and PH{sub 2} = 20.3 MPa, with excessively high temperatures (T {gt} 420{sup o}C) leading to a decrease in diesel selectivity. The fuels produced by the hydroprocessing of the straight-run Suplex distillate fraction have properties that make them desirable as blending components, with the diesel fraction having a cetane number of 48 and a density of 0.90 kg/L. The gasoline fraction was found to have a research octane number (RON) of 66 and (N + 2A) value of 100, making it ideal as a feedstock for catalytic reforming and further blending with Fischer-Tropsch liquids. 44 refs., 9 figs., 12 tabs.

Modeling heat and mass transport phenomena at higher temperatures in solar distillation systems - The Chilton-Colburn analogy  

Science Conference Proceedings (OSTI)

In the present investigation efforts have been devoted towards developing an analysis suitable for heat and mass transfer processes modeling in solar distillation systems, when they are operating at higher temperatures. For this purpose the use of Lewis relation is not new although its validity is based on the assumptions of identical boundary layer concentration and temperature distributions, as well as low mass flux conditions, which are not usually met in solar distillation systems operating at higher temperatures associated with considerable mass transfer rates. The present analysis, taking into consideration these conditions and the temperature dependence of all pertinent thermophysical properties of the saturated binary mixture of water vapor and dry air, leads to the development of an improved predictive accuracy model. This model, having undergone successful first order validation against earlier reported measurements from the literature, appears to offer more accurate predictions of the transport processes and mass flow rate yield of solar stills when operated at elevated temperatures.

Capacity Value of Wind Power  

Science Conference Proceedings (OSTI)

Power systems are planned such that they have adequate generation capacity to meet the load, according to a defined reliability target. The increase in the penetration of wind generation in recent years has led to a number of challenges for the planning and operation of power systems. A key metric for system adequacy is the capacity value of generation. The capacity value of a generator is the contribution that a given generator makes to overall system adequacy. The variable and stochastic nature of wind sets it apart from conventional energy sources. As a result, the modeling of wind generation in the same manner as conventional generation for capacity value calculations is inappropriate. In this paper a preferred method for calculation of the capacity value of wind is described and a discussion of the pertinent issues surrounding it is given. Approximate methods for the calculation are also described with their limitations highlighted. The outcome of recent wind capacity value analyses in Europe and North America are highlighted with a description of open research questions also given.

FRACTIONAL DISTILLATION SEPARATION OF PLUTONIUM VALUES FROM LIGHT ELEMENT VALUES  

DOE Patents (OSTI)

A process is described for removing light element impurities from plutonium. It has been found that plutonium contaminated with impurities may be purified by converting the plutonium to a halide and purifying the halide by a fractional distillation whereby impurities may be distilled from the plutonium halide. A particularly effective method includes the step of forming a lower halide such as the trior tetrahalide and distilling the halide under conditions such that no decomposition of the halide occurs. Molecular distillation methods are particularly suitable for this process. The apparatus may comprise an evaporation plate with means for heating it and a condenser surface with means for cooling it. The condenser surface is placed at a distance from the evaporating surface less than the mean free path of molecular travel of the material being distilled at the pressure and temperature used. The entire evaporating system is evacuated until the pressure is about 10/sup -4/ millimeters of mercury. A high temperuture method is presented for sealing porous materials such as carbon or graphite that may be used as a support or a moderator in a nuclear reactor. The carbon body is subjected to two surface heats simultaneously in an inert atmosphere; the surface to be sealed is heated to 1500 degrees centigrade; and another surface is heated to 300 degrees centigrade, whereupon the carbon vaporizes and flows to the cooler surface where it is deposited to seal that surface. This method may be used to seal a nuclear fuel in the carbon structure.

We prove that the routing capacity of every network is achievable and rational, we present an algorithm for its computation, and we prove that every non-negative rational number is the routing capacity of some network. We also determine the routing capacity for various example networks. Finally, we discuss the extension of routing capacity to fractional coding solutions and show that the coding capacity of a network is independent of the alphabet used.

Imports were the largest source of new supply that arrived to relieve the imbalance that was behind the price spike. This graph shows the dramatic increase on a calendar monthly average basis. During the three weeks ending February 25, distillate fuel oil imports averaged 566 thousand barrels per day. During the prior four weeks, imports only averaged 162 thousand barrels per day. Refinery production on the East Coast also increased. For the three weeks ending February 25, East Coast distillate production averaged 478 thousand barrels per day, which was an increase of about 91 thousand barrels per day or 24% over the prior four weeks.

Extraction of tocopherols from deodorizer distillates: laboratory-scale evaluations  

E-Print Network (OSTI)

The tocopherols are valuable components of deodorizer distillate. Due to the limitations in the existing extraction methods, it is imperative that new processing parameters for extraction and concentration of tocopherols from deodorizer distillate be developed. For this purpose, an analytical method for the determination of both tocopherols and tocopherol succinates simultaneously was developed. Crystallization, flat-sheet membrane separation, and a combined process were evaluated. Individual steps of the combined process were defined. They were: 1). Crystallization of deodorizer distillate; 2). Succination; 3). Membrane separation; and 4). Second stage membrane separation. The succination process converted over 90% of the tocopherols to tocopherol succinates. Crystallization and flat-sheet membrane separations increased tocopherols concentration about 2% and 6%, respectively. The final tocopherols concentration in the combined process was twice that of the original tocopherol sample.

APPLICATION OF VACUUM SALT DISTILLATION TECHNOLOGY FOR THE REMOVAL OF FLUORIDE AND CHLORIDE FROM LEGACY FISSILE MATERIALS  

Science Conference Proceedings (OSTI)

Between September 2009 and January 2011, the Savannah River National Laboratory (SRNL) and the Savannah River Site (SRS) HB-Line Facility designed, developed, tested, and successfully deployed a production-scale system for the distillation of sodium chloride (NaCl) and potassium chloride (KCl) from plutonium oxide (PuO{sub 2}). Subsequent efforts adapted the vacuum salt distillation (VSD) technology for the removal of chloride and fluoride from less-volatile halide salts at the same process temperature and vacuum. Calcium chloride (CaCl{sub 2}), calcium fluoride (CaF{sub 2}), and plutonium fluoride (PuF{sub 3}) were of particular concern. To enable the use of the same operating conditions for the distillation process, SRNL employed in situ exchange reactions to convert the less-volatile halide salts to compounds that facilitated the distillation of halide without removal of plutonium. SRNL demonstrated the removal of halide from CaCl{sub 2}, CaF{sub 2} and PuF{sub 3} below 1000 C using VSD technology.

Capacity Value of Concentrating Solar Power Plants  

DOE Green Energy (OSTI)

This study estimates the capacity value of a concentrating solar power (CSP) plant at a variety of locations within the western United States. This is done by optimizing the operation of the CSP plant and by using the effective load carrying capability (ELCC) metric, which is a standard reliability-based capacity value estimation technique. Although the ELCC metric is the most accurate estimation technique, we show that a simpler capacity-factor-based approximation method can closely estimate the ELCC value. Without storage, the capacity value of CSP plants varies widely depending on the year and solar multiple. The average capacity value of plants evaluated ranged from 45%?90% with a solar multiple range of 1.0-1.5. When introducing thermal energy storage (TES), the capacity value of the CSP plant is more difficult to estimate since one must account for energy in storage. We apply a capacity-factor-based technique under two different market settings: an energy-only market and an energy and capacity market. Our results show that adding TES to a CSP plant can increase its capacity value significantly at all of the locations. Adding a single hour of TES significantly increases the capacity value above the no-TES case, and with four hours of storage or more, the average capacity value at all locations exceeds 90%.

Modeling Capacity Reservation Contract  

E-Print Network (OSTI)

In this paper we model a scenario where a chip designer (buyer) buys capacity from chip manufacturers (suppliers) in the presence of demand uncertainty faced by the buyer. We assume that the buyer knows the probability distribution of his demand. The supplier offers the buyer to reserve capacity in advance at a price that is lower than the historical average of the spot price. The supplier’s price (if the buyer reserves capacity in advance) is function of her capacity, demand for her capacity, unit production cost, the average spot market price and the amount of capacity reserved by the buyer. Based on these parameters we derive the price the suppliers will charge. We formulate the problem from the buyer’s perspective. The buyer’s decisions are how much capacity to reserve and from how many suppliers. The optimal solution is obtained numerically. Our model addresses the following issues that are not covered in the current literature on capacity reservation models. In the existing literature the supplier’s price is an exogenous parameter. We model the supplier’s price from relevant parameters mentioned above. This makes our model richer. For example, if the expected capacity utilization for the supplier is likely to be low then the supplier will charge a lower price for capacity reservation. In reality, the buyer sources from multiple suppliers. Most mathematical models on capacity reservation, we are aware of, assumes a single buyer and a single supplier. We generalize this to a single buyer and multiple suppliers.

Subsite Retrieval: A Novel Concept for Topic Distillation  

E-Print Network (OSTI)

Abstract. Topic distillation is one of the main information needs when users search the Web. In previous approaches to topic distillation, the single page was treated as the basic searching unit. This strategy is inherited from general information retrieval, which has not fully utilized the structure information of the Web. In this paper, we propose a novel concept for topic distillation, named subsite retrieval, in which the basic searching unit is the subsite instead of the single page. As indicated by the name, the subsite is a subset of website, consisting of a structural collection of pages. The key of subsite retrieval is to extract effective features to represent a subsite by utilizing both the content in each page and the structural information in the subsite. Specifically, we propose a so-called PI algorithm for this purpose, which is based on the modeling of website growth. Testing on the topic distillation task of TREC 2003 and TREC 2004, subsite retrieval gets significant improvement of retrieval performance over the previous single page based methods. 1

Peak Underground Working Natural Gas Storage Capacity  

Gasoline and Diesel Fuel Update (EIA)

Definitions Definitions Definitions Since 2006, EIA has reported two measures of aggregate capacity, one based on demonstrated peak working gas storage, the other on working gas design capacity. Demonstrated Peak Working Gas Capacity: This measure sums the highest storage inventory level of working gas observed in each facility over the 5-year range from May 2005 to April 2010, as reported by the operator on the Form EIA-191M, "Monthly Underground Gas Storage Report." This data-driven estimate reflects actual operator experience. However, the timing for peaks for different fields need not coincide. Also, actual available maximum capacity for any storage facility may exceed its reported maximum storage level over the last 5 years, and is virtually certain to do so in the case of newly commissioned or expanded facilities. Therefore, this measure provides a conservative indicator of capacity that may understate the amount that can actually be stored.

Second Price Component: Spread Impacted by Distillate Supply/Demand Balance  

Gasoline and Diesel Fuel Update (EIA)

8 8 Notes: While crude oil prices will be a major factor impacting distillate prices this winter, another important factor is the U.S. distillate supply/demand balance, as measured by distillate stocks. The distillate supply/demand balance influences the spread between spot distillate and spot crude oil prices. For example, when stocks are higher than normal, the spread will be lower than usual. This spread is the price incentive that encourages or discourages changes in supply. While high stocks in the distillate market are good news for consumers, an excess is bad news for refiners. Distillate spreads during the winter of 1998-99 and throughout most of 1999 were well below average. Distillate stocks were very high during this period, partially as a result of warm weather keeping demand down.

On the Development of a Distillation Process for the Electrometallurgical Treatment of Irradiated Spent Nuclear Fuel  

Science Conference Proceedings (OSTI)

As part of the spent fuel treatment program at the Idaho National Laboratory, a vacuum distillation process is being employed for the recovery of actinide products following an electrorefining process. Separation of the actinide products from a molten salt electrolyte and cadmium is achieved by a batch operation called cathode processing. A cathode processor has been designed and developed to efficiently remove the process chemicals and consolidate the actinide products for further processing. This paper describes the fundamentals of cathode processing, the evolution of the equipment design, the operation and efficiency of the equipment, and recent developments at the cathode processor. In addition, challenges encountered during the processing of irradiated spent nuclear fuel in the cathode processor will be discussed.

Aggregate Models based on Improved Group Methods for Simulation and Optimization of Distillation Systems  

E-Print Network (OSTI)

This note deals with aggregate models for complex distillation systems in largescale flowsheets. Group methods were originally devised for simple absorber and stripper calculations with no major extensions for handling distillation. In this work, group methods are systematically analyzed and further improved by modifying some of the previously proposed approximations. As a result, the improved group method exhibits accurate predictions and this is demonstrated using simulation and optimization case studies for a variety of chemical systems and operating conditions. It is observed that the prediction of output variables is in close agreement with that of the rigorous equilibrium stage model. In case of optimization problems, the optimal number of trays and feed locations differ by only one or two trays. The aggregate model can be applied in a sequence of steps in order to improve the reliability and robustness of the solution procedure. A rounding heuristic is also proposed which can provide near-optimal solutions with a significant reduction in computational time. ?To whom correspondence should be addressed.

Distillate Stocks are Low - Especially on the East Coast  

Gasoline and Diesel Fuel Update (EIA)

8 8 Notes: Distillate stocks are normally built during the summer for use during the winter as shown by the normal band. Currently, stocks are very low for this time of year. This graph shows East Coast inventories, which at the end of August, were well below the normal band (over 9 million barrels or 19% below the low end of the band). The East Coast is about 31% lower than its 10-year average level for this time of year. We focus on the East Coast (PADD 1 ) because this a region in which heating oil is a major winter fuel. Furthermore, the East Coast consumes almost 2/3 of the nation's heating oil (high sulfur distillate). December 1999 was the turning point. Stocks were well within the normal range through November 1999, but in December, they dropped below the

Continuous variable entanglement distillation of Non-Gaussian Mixed States  

E-Print Network (OSTI)

Many different quantum information communication protocols such as teleportation, dense coding and entanglement based quantum key distribution are based on the faithful transmission of entanglement between distant location in an optical network. The distribution of entanglement in such a network is however hampered by loss and noise that is inherent in all practical quantum channels. Thus, to enable faithful transmission one must resort to the protocol of entanglement distillation. In this paper we present a detailed theoretical analysis and an experimental realization of continuous variable entanglement distillation in a channel that is inflicted by different kinds of non-Gaussian noise. The continuous variable entangled states are generated by exploiting the third order non-linearity in optical fibers, and the states are sent through a free-space laboratory channel in which the losses are altered to simulate a free-space atmospheric channel with varying losses. We use linear optical components, homodyne mea...

Collocation Methods for Distillation Design I: Model Description and Testing  

E-Print Network (OSTI)

Fast and accurate distillation design requires a model that significantly reduces the problem size while accurately approximating a full order distillation column model. Variable number of trays and variable feed tray location make optimization possible. This collocation model builds on the concepts of past collocation models for design of complex real-world separation systems. Two variable transformations make this method unique. Polynomials cannot accurately fit trajectories which flatten out. In columns, flat sections occur in the middle of large column sections, or where concentrations go to zero or one. With an exponential transformation of the tray number which maps zero to an infinite number of trays onto the range zero to one, two collocation trays can accurately simulate a large column section. With a hyperbolic tangent transformation of the mole fractions, the model can simulate columns which reach high purities. Furthermore, this model uses multiple collocation elements for ...

Both Distillate Supply and Demand Reached Extraordinary Levels This Winter  

Gasoline and Diesel Fuel Update (EIA)

6 6 Notes: This chart shows some critical differences in distillate supply and demand during this winter heating season, in comparison to the past two winters. Typically, distillate demand peaks during the winter months, but "new supply" (refinery production and net imports) cannot increase as much, so the remaining supply needed is drawn from inventories. This pattern is evident in each of the past two winter heating seasons. This winter, however, the pattern was very different, for several reasons: With inventories entering the season at extremely low levels, a "typical" winter stockdraw would have been nearly impossible, particularly in the Northeast, the region most dependent on heating oil. Demand reached near-record levels in December, as colder-than-normal

We also presented a general theory of entanglement dilution which is applicable to any non-i.i.d sequence of states.

Reactive Distillation for Esterification of Bio-based Organic Acids  

DOE Green Energy (OSTI)

The following is the final report of the three year research program to convert organic acids to their ethyl esters using reactive distillation. This report details the complete technical activities of research completed at Michigan State University for the period of October 1, 2003 to September 30, 2006, covering both reactive distillation research and development and the underlying thermodynamic and kinetic data required for successful and rigorous design of reactive distillation esterification processes. Specifically, this project has led to the development of economical, technically viable processes for ethyl lactate, triethyl citrate and diethyl succinate production, and on a larger scale has added to the overall body of knowledge on applying fermentation based organic acids as platform chemicals in the emerging biorefinery. Organic acid esters constitute an attractive class of biorenewable chemicals that are made from corn or other renewable biomass carbohydrate feedstocks and replace analogous petroleum-based compounds, thus lessening U.S. dependence on foreign petroleum and enhancing overall biorefinery viability through production of value-added chemicals in parallel with biofuels production. Further, many of these ester products are candidates for fuel (particularly biodiesel) components, and thus will serve dual roles as both industrial chemicals and fuel enhancers in the emerging bioeconomy. The technical report from MSU is organized around the ethyl esters of four important biorenewables-based acids: lactic acid, citric acid, succinic acid, and propionic acid. Literature background on esterification and reactive distillation has been provided in Section One. Work on lactic acid is covered in Sections Two through Five, citric acid esterification in Sections Six and Seven, succinic acid in Section Eight, and propionic acid in Section Nine. Section Ten covers modeling of ester and organic acid vapor pressure properties using the SPEAD (Step Potential Equilibrium and Dynamics) method.

Distillation of hydrogen isotopes for polarized HD target  

E-Print Network (OSTI)

We have developed a cryogenic distillation system to purify Hydrogen-Deuteride (HD) gas for a polarized HD target in LEPS experiments at SPring-8. A small amount of ortho-H$_2$ ($\\sim$0.01%) in the HD gas plays an important role in efficiently polarizing the HD target. Since there are 1$\\sim$5% impurities of H$_2$ and D$_2$ in commercially available HD gases, it is inevitable that the HD gas is purified up to $\\sim$99.99%. The distillation system has a cryogenic pot (17$\\sim$21 K) containing many small stainless steel cells called Heli-pack. Commercial HD gas with an amount of 5.2 mol is fed into the pot. We carried out three distillation runs by changing temperatures (17.5 K and 20.5 K) and gas extraction speeds (1.3 ml/min and 5.2 ml/min). The extracted gas was analyzed by using a gas analyzer system combining a quadrupole mass spectrometer with a gas chromatograph. The HD gas of 1 mol with a purity better than 99.99% has been successfully obtained. The effective NTS (Number of Theoretical Stages), which is an indicator of the distillator performances, is obtained as 37.2$\\pm$0.6. This value is in reasonable agreement with a designed value of 37.9. The HD target is expected to be efficiently polarized under a well-controlled condition by doping an optimal amount of ortho-H$_2$ to the purified HD gas.

Optimization of reactive distillation processes with simulated annealing  

E-Print Network (OSTI)

A simulated annealing-based algorithm (MSIMPSA) suitable for the optimization of mixed integer non-linear programming (MINLP) problems was applied to the synthesis of a non-equilibrium reactive distillation column. A simulation model based on an extension of conventional distillation is proposed for the simulation step of the optimization problem. In the case of ideal vapor}liquid equilibrium, the simulation results are similar to those obtained by Ciric and Gu (1994, AIChE Journal, 40(9), 1479) using the GAMS environment and to those obtained with the AspenPlus modular simulator. The optimization results are also similar to those previously reported and similar to those using an adaptive random search algorithm (MSGA). The optimizations were also performed with non-ideal vapor}liquid equilibrium, considering either distributed feed and reaction trays or single feed and reaction tray. The results show that the optimized objective function values are very similar, and mostly independent of the number of trays and of the reaction distribution. It is shown that the proposed simulation/optimization equation-oriented environments are capable of providing optimized solutions which are close to the global optimum, and reveal its adequacy for the optimization of reactive distillation

Unification of methods for determining distillation curve of oils  

Science Conference Proceedings (OSTI)

For the determination of the distillation curve of oils, various types of flask are recommended by industry-branch standards (OST) and specifications (TU). For example, TU 6-02-1072-86 for PEF fluid and TU 6-02-921-74 for the chlorofluorocarbon oil UF specify a Claisen flask (GOST 25336-82); the standard OST 38.01402-86 for mineral-base vacuum oils specifies a specially designed flask; TU 6-01-26-54-85 for Alkarene type vacuum oils specifies a Bogdanov flask. The latter two flasks are not included in any State (GOST) standards for chemical laboratory ware and hence are not in regular production. The accuracy in determining the distillation curve depends on the separating ability of the flask. Flasks designed as shown do not allow return of part of the condensate to the still section, so that it is impossible to regulate the reflux rate and hence impossible to obtain any reliable data on the fractional composition of the product and the distillation temperature. The Claisen and Bogdanov flasks, which have a developed surface, are more suitable for fractionation of oils.

On channels with finite Holevo capacity  

E-Print Network (OSTI)

We consider a nontrivial class of infinite dimensional quantum channels characterized by finiteness of the Holevo capacity. Some general properties of channels of this class are described. In particular, a special sufficient condition of existence of an optimal measure is obtained and examples of channels with no optimal measure are constructed. It is shown that each channel with finite Holevo capacity has a natural extension to the set of all positive normalized functionals on the algebra of all bounded operators. General properties of such an extension are described. The class of infinite dimensional channels, for which the Holevo capacity can be explicitly determined, is considered.

Lateral Capacity Exchange and Its Impact on Capacity Investment Decisions  

E-Print Network (OSTI)

We study the problem of capacity exchange between two …rms in anticipation of the mismatch between demand and capacity and its impact on …rm’s capacity investment decisions. For given capacity investment levels of the two …rms, we demonstrate how capacity price may be determined and how much capacity should be exchanged when either manufacturer acts as a Stackelberg leader in the capacity exchange game. By benchmarking against the centralized system, we show that a side payment may be used to coordinate the capacity exchange decisions. We then study the …rms’capacity investment decisions using a biform game framework in which capacity investment decisions are made individually and exchange decisions are made as in a centralized system. We demonstrate the existence and uniqueness of the Nash equilibrium capacity investment levels and study the impact of …rms’share of the capacity exchange surplus on their capacity investment levels.

The robustness of magic state distillation against errors in Clifford gates  

E-Print Network (OSTI)

Quantum error correction and fault-tolerance have provided the possibility for large scale quantum computations without a detrimental loss of quantum information. A very natural class of gates for fault-tolerant quantum computation is the Clifford gate set and as such their usefulness for universal quantum computation is of great interest. Clifford group gates augmented by magic state preparation give the possibility of simulating universal quantum computation. However, experimentally one cannot expect to perfectly prepare magic states. Nonetheless, it has been shown that by repeatedly applying operations from the Clifford group and measurements in the Pauli basis, the fidelity of noisy prepared magic states can be increased arbitrarily close to a pure magic state [1]. We investigate the robustness of magic state distillation to perturbations of the initial states to arbitrary locations in the Bloch sphere due to noise. Additionally, we consider a depolarizing noise model on the quantum gates in the decoding ...

Catalytic hydroprocessing of shale oil to produce distillate fuels  

DOE Green Energy (OSTI)

Results are presented of a Chevron Research Company study sponsored by the Energy Research and Development Administration (ERDA) to demonstrate the feasibility of converting whole shale oil to a synthetic crude resembling a typical petroleum distillate. The synthetic crude thus produced can then be processed, in conventional petroleum-refining facilities, to transportation fuels such as high octane gasoline, diesel, and jet fuel. The raw shale oil feed used is a typical Colorado shale oil produced in a surface retort in the so-called indirectly heated mode. It is shown that whole shale oil can be catalytically hydrodenitrified to reduce the nitrogen to levels as low as one part per million in a single catalytic stage. However, for economic reasons, it appears preferable to denitrify to about 0.05 wt % nitrogen. The resulting synthetic crude resembles a petroleum distillate that can be fractionated and further processed as necessary in conventional petroleum refining facilities. Shale oil contains about 0.6% sulfur. Sulfur is more easily removed by hydrofining than is nitrogen; therefore, only a few parts per million of sulfur remain at a product nitrogen of 0.05 wt %. Oxygen contained in the shale oil is also reduced to low levels during hydrodenitrification. The shale oil contains appreciable quantities of iron and arsenic which are also potential catalyst poisons. These metals are removed by a guard bed placed upstream from the hydrofining catalyst. Based on correlations, the naphthas from the shale oil hydrofiner can readily be upgraded to high octane gasolines by catalytic reforming. The middle distillate fractions may require some additional hydrofining to produce salable diesel or jet fuel. The technology is available, and pilot plant studies are scheduled to verify diesel hydrofiner performance.

Distilling single-photon entanglement from photon loss and decoherence  

E-Print Network (OSTI)

Single-photon entanglement may be the simplest type of entanglement but it is of vice importance in quantum communication. Here we present a practical protocol for distilling the single-photon entanglement from both photon loss and decoherence. With the help of some local single photons, the probability of single photon loss can be decreased and the less-entangled state can also be recovered to maximally entangled state simultaneously. It only requires some linear optical elements which makes it feasible in current experiment condition. This protocol might find applications in current quantum communications based on the quantum repeaters.

Distilling quantum entanglement via mode-matched filtering  

Science Conference Proceedings (OSTI)

We propose an avenue toward distillation of quantum entanglement that is implemented by directly passing the entangled qubits through a mode-matched filter. This approach can be applied to a common class of entanglement impurities appearing in photonic systems, where the impurities inherently occupy different spatiotemporal modes than the entangled qubits. As a specific application, we show that our method can be used to significantly purify the telecom-band entanglement generated via the Kerr nonlinearity in single-mode fibers where a substantial amount of Raman-scattering noise is concomitantly produced.

Geothermal Energy Market Study on the Atlantic Coastal Plain: Technical Feasibility of use of Eastern Geothermal Energy in Vacuum Distillation of Ethanol Fuel  

DOE Green Energy (OSTI)

The DOE is studying availability, economics, and uses of geothermal energy. These studies are being conducted to assure maximum cost-effective use of geothermal resources. The DOE is also aiding development of a viable ethanol fuel industry. One important point of the ethanol program is to encourage use of non-fossil fuels, such as geothermal energy, as process heat to manufacture ethanol. Geothermal waters available in the eastern US tend to be lower in temperature (180 F or less) than those available in the western states (above 250 F). Technically feasible use of eastern geothermal energy for ethanol process heat requires use of technology that lowers ethanol process temperature requirements. Vacuum (subatmospheric) distillation is one such technology. This study, then, addresses technical feasibility of use of geothermal energy to provide process heat to ethanol distillation units operated at vacuum pressures. They conducted this study by performing energy balances on conventional and vacuum ethanol processes of ten million gallons per year size. Energy and temperature requirements for these processes were obtained from the literature or were estimated (for process units or technologies not covered in available literature). Data on available temperature and energy of eastern geothermal resources was obtained from the literature. These data were compared to ethanol process requirements, assuming a 150 F geothermal resource temperature. Conventional ethanol processes require temperatures of 221 F for mash cooking to 240 F for stripping. Fermentation, conducted at 90 F, is exothermic and requires no process heat. All temperature requirements except those for fermentation exceed assumed geothermal temperatures of 150 F. They assumed a 130 millimeter distillation pressure for the vacuum process. It requires temperatures of 221 F for mash cooking and 140 F for distillation. Data indicate lower energy requirements for the vacuum ethanol process (30 million BTUs per hour) than for the conventional process (36 million BTUs per hour). Lower energy requirements result from improved process energy recovery. Data examined in this study indicate feasible use of eastern geothermal heated waters (150 F) to provide process heat for vacuum (130 mm Hg) ethanol distillation units. Data indicate additional heat sources are needed to raise geothermal temperatures to the 200 F level required by mash cooking. Data also indicate potential savings in overall process energy use through use of vacuum distillation technology. Further study is needed to confirm conclusions reached during this study. Additional work includes obtaining energy use data from vacuum ethanol distillation units currently operating in the 130 millimeter pressure range; economic analysis of different vacuum pressures to select an optimum; and operation of a pilot geothermally heated vacuum column to produce confirmatory process data.

Distillation Protocols for Mixed States of Multilevel Qubits and the Quantum Renormalization Group  

E-Print Network (OSTI)

We study several properties of distillation protocols to purify multilevel qubit states (qudits) when applied to a certain family of initial mixed bipartite states. We find that it is possible to use qudits states to increase the stability region obtained with the flow equations to distill qubits. In particular, for qutrits we get the phase diagram of the distillation process with a rich structure of fixed points. We investigate the large-$D$ limit of qudits protocols and find an analytical solution in the continuum limit. The general solution of the distillation recursion relations is presented in an appendix. We stress the notion of weight amplification for distillation protocols as opposed to the quantum amplitude amplification that appears in the Grover algorithm. Likewise, we investigate the relations between quantum distillation and quantum renormalization processes.

Capacity Definitions for General Channels with Receiver Side Information  

E-Print Network (OSTI)

We consider three capacity definitions for general channels with channel side information at the receiver, where the channel is modeled as a sequence of finite dimensional conditional distributions not necessarily stationary, ergodic, or information stable. The {\\em Shannon capacity} is the highest rate asymptotically achievable with arbitrarily small error probability. The {\\em capacity versus outage} is the highest rate asymptotically achievable with a given probability of decoder-recognized outage. The {\\em expected capacity} is the highest average rate asymptotically achievable with a single encoder and multiple decoders, where the channel side information determines the decoder in use. As a special case of channel codes for expected rate, the code for capacity versus outage has two decoders: one operates in the non-outage states and decodes all transmitted information, and the other operates in the outage states and decodes nothing. Expected capacity equals Shannon capacity for channels governed by a sta...

Experimental and analytical studies of hydrocarbon yields under dry-, steam-, and steam-with-propane distillation  

E-Print Network (OSTI)

Simulation study has shown oil production is accelerated when propane is used as an additive during steam injection. To better understand this phenomenon, distillation experiments were performed using San Ardo crude oil (12oAPI). For comparison purposes, three distillation processes were investigated: dry-, steam-, and steam-propanedistillation, the latter at the propane-to-steam mass ratio of 0.05 at steam injection rate 0.5 g/min. Two sets of the distillation experiments were carried out. In the first set of experiments, the distillation temperatures ranged from 115ºC to 300ºC. Distillation pressures ranged from 0 psig to 998 psig for steam- and steam-propane distillation. The temperature-pressure combination used represented 15ºC superheated steam conditions. In the second set of experiments, the distillation temperatures ranged from 220oC to 300oC at 260 psig. The temperature pressure combination used represented field conditions for crude oil. For both conditions, the cell was kept at each temperature plateau (cut) until no increase occurs in distillation yields. Distillation yields were collected at each cut, and the volume and weight of water and hydrocarbon measured. Based on these experiments, a thermodynamic modeling framework was developed that describes distillation effect and oil production for steam distillation experiments. The model is based on composition of crude oil, molecular weight of heavy fraction. The analytical model results are compared against the experimental data for synthetic crude and crude oil to verify the validity of the model. Main results of the study may be summarized as follows. The yields for steam distillation for saturated conditions of Tsat+15 o C and Psat is 10 % and with addition of 5% of propane to steam no significant increase occurs in distillation yields. The yields for steam distillation for field conditions of 260 psig and temperature range (220 ~300oC) is 18 % and with addition of 5% of propane to steam no significant increase in distillation yields. The results indicate that propane has minimal distillation effect on the heavy oil. This occurs possibly because of lesser amount of light fractions in the heavy oil that enhance the separation of components in the oil caused by the concentration gradient.

Microchannel Distillation of JP-8 Jet Fuel for Sulfur Content Reduction  

Science Conference Proceedings (OSTI)

In microchannel based distillation processes, thin vapor and liquid films are contacted in small channels where mass transfer is diffusion-limited. The microchannel architecture enables improvements in distillation processes. A shorter height equivalent of a theoretical plate (HETP) and therefore a more compact distillation unit can be achieved. A microchannel distillation unit was used to produce a light fraction of JP-8 fuel with reduced sulfur content for use as feed to produce fuel-cell grade hydrogen. The HETP of the microchannel unit is discussed, as well as the effects of process conditions such as feed temperature, flow rate, and reflux ratio.

Coke Gasification - A Solution to Excess Coke Capacity and High Energy Costs  

E-Print Network (OSTI)

United States crude slate is becoming heavier and generally higher in sulfur. At the same time demand of distillate products is increasing. Refiners are reworking their plans to include resid conversion via coking and approximately 230,000 BPD of new coking capacity is either under construction or announced. Even if 50 percent of the coke produced is exported, there will be an excess capacity of coke selling at less than $30/ton depending upon the sulfur content. This coke can be gasified effectively to produce medium-Btu (300 Btu/scf) gas which, in turn, can fuel the refinery furnaces to replace natural gas. Coke gasification should prove economical with natural gas price decontrol and the average price projected to rise to over $14.0 per million Btu in 1990. The paper will discuss three gasifiers - Gesellschaft fur Kohle-Technologie Gmbh (GKT), Texaco and Westinghouse which may be used for the production of medium-Btu gas from coke. The design parameters, which for coke gasification may be different from coal gasification because of the difference in physical and chemical characteristics of coke and coal, will be evaluated. Conceptual design will be performed based upon normal fuel requirements of about 20 billion Btu per day for a typical 50,000 BPD refinery. Adaptability of coke derived gas to refinery fuel systems will be discussed in terms of flame temperatures, flue gas volumes, derating and required furnace modifications. Estimates of capital and operating costs will be obtained to calculate the gas cost using the new tax laws. Finally, the GKT gasifier will be compared to the developing Texaco and Westinghouse gasifiers to assess the effect of second generation gasifiers on the economics of coke gasification.

Some problems of dynamic distributional planning for petroleum distillates in Mexico  

Science Conference Proceedings (OSTI)

This dissertation focuses on the development of mathematical models that may aid in the strategic planning of distributional operations of petroleum distillates in countries such as Mexico, where these operations are very complex involving multiple time periods, multiple commodities, several means of transportation, and uncertain demands. A new mathematical instrument for policy analysis of the west coast tanker distributional operations of Pemex regarding gasoline and diesel fuels is developed in terms of goal-interval programming formulations. Taking advantage of the special structure of these multiperiod-multicommodity formulations that would otherwise be mixed-integer programming problems, new special linear programming structures are devised which achieve integrality at extreme point solutions. This permits assessment of incremental policy changes in terms of the usual dual variables, a significant advantage. The extension of policy planning to other regions of the country, a secondary problem, is begun with a framework of modeling which comprehends inter-regional transfers. Future research will develop the corresponding intra-regional policy tools.

Experimental and analytical studies of hydrocarbon yields under dry-, steam-, and steam with propane-distillation  

E-Print Network (OSTI)

Recent experimental and simulation studies -conducted at the Department of Petroleum Engineering at Texas A&M University - confirm oil production is accelerated when propane is used as an additive during steam injection. To better understand this phenomenon, distillation experiments were performed using seven-component synthetic oil consisting of equal weights of the following alkanes: n-C5, n-C6, n-C7, n-C8, n-C9, nC10, and n-C15. For comparison purposes, three distillation processes were investigated: dry-, steam-, and steam-propane-distillation, the latter at a propane:steam mass ratio of 0.05. The injection rate of nitrogen during dry-and steam-distillation was the same as that of propane during steam-propane distillation, 0.025 g/min, with steam injection rate kept at 0.5 g/min. The distillation temperatures ranged from 115°C to 300°C and were increased in steps of 10°C. The cell was kept at each temperature plateau (cut) for 30 minutes. Distillation pressures ranged from 0 psig for dry distillation to 998 psig for steam-and steam-propane distillation. The temperature-pressure combination used represented 15°C superheated steam conditions. Distillate samples were collected at each cut, and the volume and weight of water and hydrocarbon measured. In addition, the composition of the hydrocarbon distillate was measured using a gas chromatograph. Main results of the study may be summarized as follows. First, the hydrocarbon yield at 125°C is highest with steam-propane distillation (74 wt%) compared to steam distillation (58 wt%), and lowest with dry distillation (36 wt%). This explains in part the oil production acceleration observed in steam-propane displacement experiments. Second, the final hydrocarbon yield at 300°C however is the same for the three distillation processes. This observation is in line with the fact that oil recoveries were very similar in steam- and steam-propane displacement experiments. Third, based on the yields of individual hydrocarbon components, steam-propane distillation lowers the apparent boiling points of the hydrocarbons significantly. This phenomenon may be the most fundamental effect of propane on hydrocarbon distillation, which results in a higher yield during steam-propane distillation and oil production acceleration during steam-propane displacement. Fourth, experimental K-values are higher in distillations with steam-propane for the components n-hexane, n-heptane, n-octane, and n-nonane. Fifth, vapor fugacity coefficients for each component are higher in distillations with steam-propane than with steam. Finally, Gibbs excess energy is overall lower in distillations with steam-propane than with steam. The experimental results clearly indicate the importance of distillation on oil recovery during steam-or steam-propane injection. The experimental procedure and method of analysis developed in this study (for synthetic oil) will be beneficial to future researchers in understanding the effect of propane as steam additive on actual crude oils.

Quantum Zero-error Capacity  

E-Print Network (OSTI)

We define here a new kind of quantum channel capacity by extending the concept of zero-error capacity for a noisy quantum channel. The necessary requirement for which a quantum channel has zero-error capacity greater than zero is given. Finally, we point out some directions on how to calculate the zero-error capacity of such channels.

Load Capacity of Bodies  

E-Print Network (OSTI)

For the stress analysis in a plastic body $\\Omega$, we prove that there exists a maximal positive number $C$, the \\emph{load capacity ratio,} such that the body will not collapse under any external traction field $t$ bounded by $Y_{0}C$, where $Y_0$ is the elastic limit. The load capacity ratio depends only on the geometry of the body and is given by $$ \\frac{1}{C}=\\sup_{w\\in LD(\\Omega)_D} \\frac{\\int_{\\partial\\Omega}|w|dA} {\\int_{\\Omega}|\\epsilon(w)|dV}=\\left\\|\\gamma_D\\right\\|. $$ Here, $LD(\\Omega)_D$ is the space of isochoric vector fields $w$ for which the corresponding stretchings $\\epsilon(w)$ are assumed to be integrable and $\\gamma_D$ is the trace mapping assigning the boundary value $\\gamma_D(w)$ to any $w\\in LD(\\Omega)_D$.

Stocks are normally an important part of East Coast winter Stocks are normally an important part of East Coast winter distillate supply, since they are the nearest source when anything unexpected occurs, and they supply a significant portion of demand during the peak heating season. Over the last 10 years, stocks have provided about 15% of supply during the peak winter months of January and February. On average, stocks supply the East Coast with about 260 thousand barrels per day in January and 280 in February. Those supplies represent draws of about 8 million barrels in one month. In addition, East Coast refineries meet about 25% of demand during January and February, and other regions -- mostly the Gulf Coast -- supply 40-50% of the region's needs.

Synthesis and design of optimal thermal membrane distillation networks  

E-Print Network (OSTI)

Thermal membrane distillation is one of the novel separation methods in the process industry. It involves the simultaneous heat and mass transfer through a hydrophobic semipermeable membrane through the use of thermal energy to bring about the separation of a feed mixture into two streams- a permeate and a retentate stream. Traditionally, studies on this technology have focused on the performance of individual modules as a function of material of the membrane and also configuration of the membrane. However, an investigation into the performance of a network of these modules has not been conducted in the past. A hierarchical parametric programming technique for synthesis of an optimal network of these modules is presented. A global mass allocation representation involving sources and sinks was used to solve the problem and derive criteria for optimality in specific regions of the parametric space. Two case studies have been presented to illustrate the applicability of the presented methodology.

Canonical Strangeness and Distillation Effects in Hadron Production  

E-Print Network (OSTI)

Strangeness canonical ensemble for Maxwell-Boltzmann statistics is reconsidered for excited nuclear systems with non-vanishing net strangeness. A new recurrence relation method is applied to find the partition function. The method is first generalized to the case of quantum strangeness canonical ensemble. Uncertainties in calculation of the K+/pi+ excitation function are discussed. A new scenario based on the strangeness distillation effect is put forward for a possible explanation of anomalous strangeness production observed at the bombarding energy near 30 AGeV. The peaked maximum in the K+/pi+ ratio is considered as a sign of the critical end-point reached in evolution of the system rather than a latent heat jump emerging from the onset of the first order deconfinement phase transition.

Distillate Fuel Oil Imports Could Be Available - For A Price  

Gasoline and Diesel Fuel Update (EIA)

4 4 Notes: So it wasn't demand and production explains only part of the reason we got through last winter with enough stocks. The mystery is solved when you look at net imports of distillate fuel last winter. As we found out, while imports are a small contributor to supply, they are sometimes crucial. Last winter, imports were the main source of supply increase following the price spike. Previous record levels were shattered as imports came pouring into the country. The fact that Europe was enjoying a warmer-than-normal winter also encouraged exports to the United States. It was massive amounts of imports, particularly from Russia, that helped us get through last winter in as good a shape as we did. Imports are expected to be relatively normal this winter.

Effects of Ruminally Degradable Nitrogen in Diets Containing Wet Distiller’s Grains with Solubles and Steam-flaked Corn on Feedlot Cattle Performance and Carcass Characteristics  

E-Print Network (OSTI)

Wet distiller’s grains with solubles are the most common feedstuff generated by the ethanol industry, and this feedstuff has been utilized by the feedlot industry. Exploration of the effect of dietary distiller’s inclusion on the form and quantity of protein or nitrogen (N) has received little attention. Assessment of degradable N needs in diets containing wet distiller’s grains with solubles (WDGS) is needed to aid the cattle feeding industry in managing feed costs and potential environmental issues. In Exp. 1, 525 yearling steers (initial weight = 373 ±13 kg) received treatments in a 2 × 3 1 factorial. Factors included corn WDGS (15 or 30 percent of DM) and non-protein N (NPN; 0, 1.5, or 3.0 percent of DM) from urea. The control diet without corn WDGS contained 3.0 percent NPN (1.06 percent urea) and cottonseed meal. Overall gain efficiency among steers fed 15 percent corn WDGS was greatest for 1.5 percent NPN and least for 0 percent NPN (P = 0.07, quadratic), whereas gain efficiency decreased linearly (P 0.15). Dietary NPN concentration did not influence growth performance (P > 0.21). Results suggest that optimum performance for cattle fed 15 percent WDGS occurred when the diet contained between 1.5 percent and 2.25 percent NPN. However, removing all supplemental NPN was necessary to support optimum performance in diets containing 30 percent WCDG.

Capacity Value of Wind Power - Summary  

Science Conference Proceedings (OSTI)

Power systems are planned such that they have adequate generation capacity to meet the load, according to a defined reliability target. The increase in the penetration of wind generation in recent years has led to a number of challenges for the planning and operation of power systems. A key metric for generation system adequacy is the capacity value of generation. The capacity value of a generator is the contribution that a given generator makes to generation system aequacy. The variable and stochastic nature of wind sets it apart from conventional energy sources. As a result, the modeling of wind generation in the same manner as conventional generation for capacity value calculations is inappropriate. In this paper a preferred method for calculation of the capacity value of wind is described and a discussion of the pertinent issues surrounding it is given. Approximate methods for the calculation are also described with their limitations highlighted. The outcome of recent wind capacity value analyses in Europe and North America, along with some new analysis, are highlighted with a discussion of relevant issues also given.

Capacities associated with scalar signed Riesz kernels, and analytic capacity  

E-Print Network (OSTI)

The real and imaginari parts of the Cauchy kernel in the plane are scalar Riesz kernels of homogeneity -1. One can associate with each of them a natural notion of capacity related to bounded potentials. The main result of the paper asserts that these capacities are comparable to classical analytic capacity, thus stressing the real variables nature of analytic capacity. Higher dimensional versions of this result are also considered.

Effects of petroleum distillate on viscosity, density and surface tension of intermediate and heavy crude oils  

E-Print Network (OSTI)

Experimental and analytical studies have been carried out to better understand the effects of additives on viscosity, density and surface tension of intermediate and heavy crude oils. The studies have been conducted for the following oil samples: San Francisco oil from Columbia with specific gravity of 28o-29o API, Duri oil with gravity of 19o-21o API, Jobo oil with gravity of 8o-9o API and San Ardo oil gravity of 11o-13o API. The additive used in all of the experiments is petroleum distillate. The experiments consist of using petroleum distillate as an additive for different samples of heavy crude oils. The experiments include making a mixture by adding petroleum distillate to oil samples and measuring surface tension, viscosity and density of pure oil samples and mixtures at different temperatures. The petroleum distillate/oil ratios are the following ratios: 1:100, 2:100, 3:100, 4:100 and 5:100. Experimental results showed that use of petroleum distillate as an additive increases API gravity and leads to reduction in viscosity and surface tension for all the samples. Results showed for all petroleum distillate/oil ratios viscosity and interfacial tension decreases with temperature. As petroleum distillate/oil ratio increases, oil viscosity and surface tension decrease more significantly at lower temperatures than at higher temperatures. After all experiments were completed an analytical correlation was done based on the experiment results to develop “mixing rules”. Using this correlation viscosity, density and surface tension of different petroleum distillate/oil mixtures were obtained (output).These had properties of pure oil and petroleum distillate, mixture ratios and temperatures at which measurement is supposed to be done (output). Using this correlation a good match was achieved. For all of the cases (viscosity, density and surface tension), correlation coefficient (R²) was more than 0.9 which proved to be optimum for a really good match.

Chemical and biological effects of heavy distillate recycle in the SRC-II process  

DOE Green Energy (OSTI)

Recent work from the Merriam Laboratory continuous coal liquefaction units shows that heavy distillate from the SRC-II process can be recycled to extinction, and hence a distillate product boiling entirely below 310/sup 0/C (590/sup 0/F) (or other selected boiling points) is feasible. In these runs distillate yield was not reduced; gas make was unaffected; and hydrogen consumption was increased only slightly, in keeping with the generally higher hydrogen content of lighter end products. Total distillate yield (C/sub 5/-590/sup 0/F) was 56 wt %, MAF coal in runs with subbituminous coal from the Amax Belle Ayr mine. Product endpoint is well below 371/sup 0/C (700/sup 0/F), the temperature above which coal distillates appear to become genotoxic; and the product was shown to be free of mutagenic activity in the Ames test. Chemical analyses showed both the < 270/sup 0/C (< 518/sup 0/F) and the < 310/sup 0/C (< 590/sup 0/F) distillates to be essentially devoid of several reference polycyclic compounds known to be carcinogenic in laboratory animals. Tests for tumorigenic or carcinogenic activity were not carried out on these materials. However, a comparison of chemical data from the Merriam heavy distillate samples with data on the other SRC-II distillates where carcinogenesis or tumorigenesis data is available leads to the expectation that < 371/sup 0/C (< 700/sup 0/F) materials from the Merriam Laboratory will have greatly reduced tumorigenic and carcinogenic activity in skin painting tests. Other studies suggest the product should be more readily upgraded than full-range (C/sub 5/-900/sup 0/F) distillate.

We investigate quantum repeaters in the context of quantum key distribution. We optimize the secret key rate per memory per second with respect to different distillation protocols and distillation strategies. For this purpose, we also derive an analytical expression for the average number of entangled pairs created by the quantum repeater, including classical communication times for entanglement swapping and entanglement distillation. We investigate the impact of this classical communication time on the secret key rate. We finally study the effect of the detector efficiency on the secret key rate.

An Adaptive Entanglement Distillation Scheme Using Quantum Low Density Parity Check Codes  

E-Print Network (OSTI)

Quantum low density parity check (QLDPC) codes are useful primitives for quantum information processing because they can be encoded and decoded efficiently. Besides, the error correcting capability of a few QLDPC codes exceeds the quantum Gilbert-Varshamov bound. Here, we report a numerical performance analysis of an adaptive entanglement distillation scheme using QLDPC codes. In particular, we find that the expected yield of our adaptive distillation scheme to combat depolarization errors exceed that of Leung and Shor whenever the error probability is less than about 0.07 or greater than about 0.28. This finding illustrates the effectiveness of using QLDPC codes in entanglement distillation.

Stable Isotope Enrichment by Thermal Diffusion, Chemical Exchange, and Distillation  

SciTech Connect

Applications of stable isotopes in medicine are becoming more widespread. This has resulted from the increased availability and reduced cost of these isotopes and the improved reliability and sensitivity of detection techniques such as carbon-13 nuclear magnetic resonance. Isotopes are used in compounds labeled with either the stable isotope itself, such as carbon-13 and oxygen-18, or with the radioactive isotope that can be produced by irradiating the stable isotope, such as the irradiation of xenon-124 to produce iodine-125. As the demand for stable isotopes increases, larger scale production facilities will be justifiable. The increased size of production facilities should result in yet lower unit selling prices. A large number of methods has been suggested for the separation of stable isotopes. This paper concerns itself with four methods which have proven extremely useful for the separation of the isotopes of low and medium atomic weight elements. The four processes discussed are gas phase thermal diffusion, liquid phase thermal diffusion, chemical exchange, and distillation.
