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.
