SEPARATION MEMBRANE MODULE

摘要

PURPOSE:To increase the recovery rate of a concentrate with respect to the amt. of a mixture supplied and to obtain the title highly efficient compact separation membrane module by providing plural membrane cells furnished with a permselective membrane in the module, and connecting membrane chambers on the supply side of a mixture of gases or liqs. in series. CONSTITUTION:A permeable membrane 1 for selectively permeating the specified components in a gaseous mixture is supported by an air-permeable urethane foam 2, and the permeable membrane 1 is air-tightly fixed to a holding frame 3 with a double-sided adhesive tape 4 to obtain a unit cell. The separation membrane cells 5 are laminated to form the gas separation membrane module. The gaseous mixture to be separated is introduced into the module from a supply port 6-a, passed through the respective separation membrane cells in series, and recovered from a recovery port 6-b. The gas m=permeated through the membrane is discharged to the outside of the module through the discharge port 5-a of each separation membrane cell 5.
