Title:
DISTILLATION DEVICE AND DISTILLATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/048724
Kind Code:
A1
Abstract:
This distillation device comprises: a batch-type distillation column; a reboiler that performs heating in order to evaporate a liquid, which is a process fluid supplied to the distillation column, to form vapor; a volumetric compressor that causes a fluid for heating the liquid to flow in so as to raise the pressure and temperature of the fluid and supply the fluid to the reboiler; a condenser for condensing column top vapor of the distillation column to form a condensate; a distillate vent part for venting the condensate condensed by the condenser; and a column bottom liquid venting part that vents a residual liquid inside the distillation column. The compressor has an actual volume flow rate adjustment mechanism for changing the actual volume flow rate of the fluid the pressure and temperature of which is increased by the compressor in accordance with a change in the heating temperature required by the reboiler during operation of the distillation device.
