Title: Thermal coupling links to liquid-only transfer streams: An enumeration method for new FTC dividing wall columns

Abstract

Novel dividing wall columns (DWCs) can be obtained by converting thermal couplings to liquid-only transfer streams. We develop a simple four-step method to generate a complete set of DWCs containing n - 2 dividing walls, for a given n-component fully thermally coupled (FTC) distillation. Among the novel DWCs, some easy-to-operate DWCs possess the property that the vapor flow in every section of the DWC can be controlled during operation by means that are external to the column. We develop a simple method to enumerate all such easy-to-operate DWCs. We expect that the easy-to-operate DWCs can be operated close-to-optimality; leading to a successful industrial implementation of the n-component (n ≥ 3) FTC distillation in the form of a DWC. As an illustration, we show figures of all easy-to-operate DWCs with two dividing walls for the four-component FTC distillation.

A systematic method to synthesize all dividing wall columns for n ‐component separation: Part II

Journal Article Madenoor Ramapriya, Gautham ; Tawarmalani, Mohit ; Agrawal, Rakesh - AIChE Journal

We present a simple rule that, for the first time, enables exhaustive enumeration of dividing wall columns (DWCs) corresponding to any given thermally coupled distillation column‐configuration. With the successive application of our rule, every partition in a DWC can be extended all the way to the top and/or to the bottom of a column without losing thermodynamic equivalence to the original thermally coupled configuration. This leads to easy‐to‐operate DWCs with possible control/regulation of each and every vapor split by external means. As a result, we conclude that any given DWC can be transformed into a thermodynamically equivalent form that ismore »« less

A systematic method to synthesize all dividing wall columns for n ‐component separation—Part I

Journal Article Madenoor Ramapriya, Gautham ; Tawarmalani, Mohit ; Agrawal, Rakesh - AIChE Journal

We present an easy‐to‐use step‐wise procedure to synthesize an initial‐dividing wall column (i‐DWC) from any given n‐component basic distillation column sequence or its thermally coupled derivative. The procedure to be used is dependent on the nature of the distillation column sequence that is to be converted into a DWC, and comprises of an intuitive set of steps that we demonstrate through examples. It is noteworthy that, even for a ternary distillation, 15 potentially useful DWCs, some of which had been missing from the literature, have now been identified. This work significantly expands the search space of useful DWCs to separatemore »« less

Process Intensification in Multicomponent Distillation: A Review of Recent Advancements

Journal Article Jiang, Zheyu ; Agrawal, Rakesh - Chemical Engineering Research and Design

Process Intensification (PI) is an emerging concept in chemical engineering that describes the design innovations that lead to significant shrinkage in size and boost in efficiency of a process plant. Distillation, the most commonly used separation technique in the chemical industry, is a crucial component of PI. We systematically discuss the following aspects of PI in non-azeotropic multicomponent distillation: 1) Introducing thermal couplings to eliminate intermediate reboilers and condensers to save energy and capital cost; 2) Improving operability of thermally coupled columns by means of eliminating vapor streams in thermal couplings with only liquid transfers or column section rearrangement; 3)more »« less

Static and Dynamic Intensification of Water–Ethylene Glycol Separation Using a Dividing Wall Column

Journal Article Yan, Lingqing ; Witt, Paul M. ; Edgar, Thomas F. ; ... - Industrial and Engineering Chemistry Research

This paper makes several first-of-a-kind contributions toward “double intensification” (static/dynamic) of distillation systems, focusing in particular on the energy-intensive separation of a mixture of water and ethylene glycols. First, we demonstrate that a dividing wall column (DWC) can be an appropriate choice for separating wide-boiling zeotropic mixtures. Additionally, we show that the conventional DWC configuration where the wall is in the “middle” should be discarded in favor of a less frequently encountered “common-bottom” setup. For the mixture considered, choosing a DWC in lieu of a conventional two-column sequence can lead to over 6% energy cost savings and a 5% reductionmore »« less

Minimum Energy of Multicomponent Distillation Systems Using Minimum Additional Heat and Mass Integration Sections

Journal Article Jiang, Zheyu ; Ramapriya, Gautham Madenoor ; Tawarmalani, Mohit ; ... - AIChE Journal

Heat and mass integration to consolidate distillation columns in a multicomponent distillation configuration can lead to a number of new energy efficient and cost‐effective configurations. In this work, a powerful and simple‐to‐use fact about heat and mass integration is identified. The newly developed heat and mass integrated configurations, which we call as HMP configurations, involve first introducing thermal couplings to all intermediate transfer streams, followed by consolidating columns associated with a lighter pure product reboiler and a heavier pure product condenser. A systematic method of enumerating all HMP configurations is introduced. The energy savings of HMP configurations is compared withmore »« less
