With the aid of the McCabe–Thiele diagram, heuristic synthesis of an internally heat-integrated distillation column is addressed in this work. A new scheme for internal heat integration between a rectifying section and a stripping section is derived with the introduction of double-feed arrangement. The process configuration is characterized by its high thermodynamic efficiency and strong resilience to changes in operating conditions. Separation of a binary close-boiling mixture is conducted and the results obtained corroborate the advantages.
