Review of Heuristic Rules and Complex Column Arrangements for the Sequencing of Multicomponent Distillation Column
Abstract: An ordinary distillation column separates a binary feed into two products, but multi-component mixtures need more complex separation sequences. For a ternary mixture of component ABC, the separation can follow a direct sequence (A/BC, B/C) or an indirect sequence (AB/C, A/B), in which the direct sequence is preferred due to the lower operating cost. The heuristic rules based sequencing can be adapted for multi-component complex feed. As the number of …
