Abstract

A method and an extractive distillation column for the recovery of thermal energy in extractive distillation with a selective solvent in an extractive distillation column and the separation of the extracted substances and the solvent in a solvent distillation column, separated from the extractive distillation, characterized in that the product is extracted from the lower end plate of an extractive distillation column equipped with a heated kettle, providing this product with heat with the regenerated solvent, extracted in a liquid and hot state from the base of the column extractive distillation by indirect heat exchange.
