Document Type and Number:
WIPO Patent Application WO/2019/102871
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a solvent dehydration system 1 that is capable of efficiently dehydrating a mixed liquid X2 by supplying the mixed liquid X2, which is at a stable temperature, to a pervaporation device 40; and a solvent dehydration method. A solvent dehydration system 1 which is provided with: a pervaporation device 40 which dehydrates a mixed liquid X2 of a water-soluble hydrocarbon solvent S and water; a third supply path P3 which supplies the mixed liquid X2 to the pervaporation device 40; and a heating means which heats the mixed liquid X2 to be supplied to the pervaporation device 40. This solvent dehydration system 1 is characterized by being provided with a vacuum distillation regeneration device 20 which generates the mixed liquid X2, and is also characterized in that the vacuum distillation regeneration device 20 is connected to the pervaporation device 40 via a second supply path P2 and the third supply path P3.
