Abstract

The system relates to an internal-reflux distillation column that integrates a rotating heat exchanger as the structured filling. The column (container 10) is a vertical vessel (axis X) with a lower vapour inlet, a condensate outlet, and a top vapour outlet (15) connected to an external condenser (22). A distillate-reflux inlet (18) near the head allows part of the condensed product to be returned to the column. A heat exchanger (5) is mounted inside on a shaft (6) that rotates around axis X, driven by a motor (60); it operates in counter-current mode with a refrigeration fluid supplied through internal ducts (610,620). The rotor may be a finned tube, the fins having a helical structure.The system is suitable for batch or continuous fractional distillation of multicomponent mixtures in pharmaceutical, fine-chemical, biotech and food processes.
