FIELD: power engineering.
SUBSTANCE: invention is intended for extraction distillation. Device for extraction distillation of the extract from the flow of raw material comprises the extraction distillation column, raw material flow supply line, solvent supply line, reboiler with internal steam distributor, connected with the extraction distillation column, water steam supply line, connected with the steam distributor, and water steam supply line from the extraction distillation column, connected with the internal steam distributor. The extract is an aromatic hydrocarbon. Reboiler is selected from the group consisting of the kettle boiler, thermosyphon reboiler and reboiler with forced circulation.
EFFECT: improvement of efficiency of extraction distillation.
