Title: CoalFleet RD&D augmentation plan for integrated gasification combined cycle (IGCC) power plants

Abstract

To help accelerate the development, demonstration, and market introduction of integrated gasification combined cycle (IGCC) and other clean coal technologies, EPRI formed the CoalFleet for Tomorrow initiative, which facilitates collaborative research by more than 50 organizations from around the world representing power generators, equipment suppliers and engineering design and construction firms, the U.S. Department of Energy, and others. This group advised EPRI as it evaluated more than 120 coal-gasification-related research projects worldwide to identify gaps or critical-path activities where additional resources and expertise could hasten the market introduction of IGCC advances. The resulting 'IGCC RD&D Augmentation Plan' describes such opportunities and how they could be addressed, for both IGCC plants to be built in the near term (by 2012-15) and over the longer term (2015-25), when demand for new electric generating capacity is expected to soar. For the near term, EPRI recommends 19 projects that could reduce the levelized cost-of-electricity for IGCC to the level of today's conventional pulverized-coal power plants with supercritical steam conditions and state-of-the-art environmental controls. For the long term, EPRI's recommended projects could reduce the levelized cost of an IGCC plant capturing 90% of the CO{sub 2} produced from the carbon in coal (for safe storagemore » away from the atmosphere) to the level of today's IGCC plants without CO{sub 2} capture. EPRI's CoalFleet for Tomorrow program is also preparing a companion RD&D augmentation plan for advanced-combustion-based (i.e., non-gasification) clean coal technologies (Report 1013221). 7 refs., 30 figs., 29 tabs., 4 apps.« less

  • An assessment of modular integrated gasification combined cycle (IGCC) power plants, based on Texaco entrained flow gasification, having a nominal capacity of 100 megawatts was conducted by Foster Wheeler. The scope of this study consisted of developing preliminary designs and relative economics for five modular IGCC power plant configurations in an effort to compare the use of air or oxygen as the oxidant for coal gasification and high temperature or low temperature processes for gas cleanup. Conceptual designs were prepared based on non-confidential information, estimated capital and operating costs, and determined the cost of electricity for five different modular IGCCmore » plant configurations. In all five plant configurations, the same gas turbine, which is commercially available for conventional fuels, was used. It was assumed that this commercially available gas turbine could be modified without additional cost impact to accept the hot low BTU fuel gas produced from air gasification with high temperature cleanup. 16 refs.« less
  • The Integrated Gasification Combined Cycle (IGCC) has been identified as an advanced coal-to-electricity power generation system with the potential for attractive performance and economic characteristics. A 100 MW demonstration of this concept has been constructed on the Southern California Edison utility system and is supplying electrical output to the grid with excellent availability. With this successful demonstration accomplished, approaches are being evaluated that will retain the attractive operational and environmental characteristics of the IGCC system while offering the potential for increased efficiency and reduced capital cost. The current system evaluation study has focused on developing the performance and economic advantagesmore » of these simplification techniques. The simplified IGCC system attempts to achieve reduction in capital cost through elimination of a number of major plant elements while maintaining or increasing the plant efficiency. The elements in the gasification subsystem are simplified by air blowing the gasifier and providing the coal in a dry feed system. By using a fixed-bed gasifier, the gas outlet temperature is reduced to a point where gas cooling is not required and the cleanup functions are performed at gasifier exit temperature directly. When these modifications are employed, the process flow schematic is reduced in complexity. Taking the simplification concept one step further, the power generation system can be modified to include direct combustion of the high-temperature coal gas without any additional heat exchange. The steam generated in the heat recovery steam generator can also be injected into the gas turbine flow path (eliminating the steam turbine) or used in a conventional steam turbine bottoming plant. 42 figs., 43 tabs.« less
  • This study investigated the merits of combining the British Gas/Lurgi slagging gasifier (BGL gasifier) with an advanced gas turbine in a 180-MWe, commercial-scale IGCC power plant located at Virginia Power's Chesterfield station. The gasification plant was fed with run-of-mine Pittsburgh No. 8 coal (containing 60 percent fines) and sized to fully load one General Electric MS7001F gas turbine at 88/degree/F ambient temperature. Seventy-five percent of the total coal fines were pelletized by agglomeration prior to gasification. All recovered tars and oils were recycled to the gasifier, while the gas liquor (process wastewater) is completely incinerated. The results of the studymore » indicate that the IGCC power plant has a very good heat rate on coal (8993 Btu/kWh at 59/degree/F and a moderate capital cost, i.e., total capital requirement, on coal ($1910/kW at 59/degree/F, with AFDC) for a commercial-scale plant in this size range. With distillate augmentation to the medium-Btu fuel gas at 59/degree/F, the capital cost drops to about $1770/kW (with AFDC). A sensitivity study compared the cost and performance of a similar IGCC power plant located at an alternate plant site owned by Detroit Edison. The capital cost for the Detroit Edison plant increased by about $200/kW, with a very slight improvement in heat rate. 16 figs., 59 tabs.« less
  • One of the inherent advantages of the Integrated Gasification Combined Cycle plant (IGCC) over other coal-based electric generation technologies is that the sulfur in the coal is converted into a form which can be removed and recovered. Extremely low sulfur oxide emissions can result. Gas treating and sulfur recovery processes for the control of sulfur emissions are an integral part of the overall IGCC plant design. There is a wide range of commercially proven technologies which are highly efficient for sulfur control. In addition, there are many developing technologies and new concepts for applying established technologies which offer potential improvementsmore » in both technical and economic performance. SFA Pacific, Inc. has completed a screening study to compare several alternative methods of removing sulfur from the gas streams generated by the Texaco coal gasification process for use in an IGCC plant. The study considered cleaning the gas made from high and low sulfur coals to produce a low sulfur fuel gas and a severely desulfurized synthesis gas (suitable for methanol synthesis), while maintaining a range of low levels of total sulfur emissions. The general approach was to compare the technical performance of the various processes in meeting the desulfurization specifications laid out in EPRI's design basis for the study. The processing scheme being tested at the Cool Water IGCC facility incorporates the Selexol acid gas removal process which is used in combination with a Claus sulfur plant and a SCOT tailgas treating unit. The study has identified several commercial systems, as well as some unusual applications, which can provide efficient removal of sulfur from the fuel gas and also produce extremely low sulfur emissions - so as to meet very stringent sulfur emissions standards. 29 refs., 8 figs., 8 tabs.« less
  • The document is the final report of a feasibility study conducted by Fluor Daniel for the Petroleum Authority of India. The purpose of the study was to determine the high priority projects for gas pipeline expansion. The high priority projects identified as a result of the study are: a new pipeline from the Erawan Complex to Khanow; a new pipeline from the 'B' structure to the Erawon Complex; and the modernization of the Supervisory Control and Data Acquisition (SCADA)/Telecommunications system. The document discusses the economic and technical feasbility of each of these projects. In addition, other topics, such as currentmore » and projected gas supply, projected gas demand and sources of additional gas, are discussed.« less
