Title:
MEMBRANE SEPARATION SYSTEM AND METHOD FOR OPERATING MEMBRANE SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/004742
Kind Code:
A1
Abstract:
The present invention provides a membrane separation system in which a retentate sufficiently suitable for reuse can be obtained by a treatment with a pervaporation membrane. This membrane separation system 100 is equipped with a membrane separation device 10. The membrane separation device 10 includes a pervaporation membrane 11. The pervaporation membrane 11 separates a fermentation broth S containing a volatile organic compound C and a microorganism producing the organic compound C into a penetrant and a retentate. The membrane separation system 100 controls the temperature of the membrane separation device 10 so that the absolute value of the difference between the temperature T1 (°C) of the fermentation broth S being fed to the membrane separation device 10 and the temperature T2 (°C) of the retentate being discharged from the membrane separation device 10 is less than 10°C.
