Title: Process Intensification in Multicomponent Distillation: A Review of Recent Advancements

Abstract

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) Enabling double and multi-effect distillation of thermally coupled configurations to further reduce heat duty; 4) Performing simultaneous heat and mass integration among thermally coupled columns to reduce the number of columns and heat duty; and 5) Conducting any thermally coupled distillation in n-product streams using 1 to n - 2 column shells with operable novel dividing wall columns. We demonstrate these aspects of PI through examples to illustrate how they lead to compact, easy-to-operate, energy efficient and cost effective multicomponent distillation system designs.
