Title:
MEMBRANE SEPARATION SYSTEM, AND METHOD FOR OPERATING MEMBRANE SEPARATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/057886
Kind Code:
A1
Abstract:
The present invention provides a membrane separation method suitable for the efficient recovery of an organic compound. A membrane separation system 100 is provided with a membrane separation unit 10, a pressure reduction unit 30, a first condensation unit 201, and a second condensation unit 202. The membrane separation unit 10 has a pervaporation membrane that separates a supply solution S containing a volatile organic compound C and a gas G into a permeated fluid S1 and a non-permeated fluid S2, and a supply space and a permeation space that are separated from each other by the pervaporation membrane. The pressure reduction unit 30 reduces the pressure in the permeation space in the membrane separation unit 10. The first condensation unit 201 is arranged between the membrane separation unit 10 and the pressure reduction unit 30, and condensates the organic compound C contained in the permeated fluid S1 discharged from the membrane separation unit 10. The second condensation unit 202 condensates the organic compound C contained in the permeated fluid S1 discharged from the pressure reduction unit 30.
