Separation Sequence Heuristics

Definition

Separation sequence heuristics are systematic approaches or rules of thumb used to determine the optimal order and selection of separation processes in a chemical engineering context. These heuristics help engineers efficiently design a sequence of operations to achieve effective separation while considering factors like cost, energy consumption, and process feasibility. Understanding these heuristics is crucial for evaluating and choosing the most suitable methods for separating components in various mixtures.
