  • Separation Using Semi-Permeable Membranes (AREA)

Abstract

PURPOSE: To recover an org. solvent in a form reutilizable directly by subjecting a resin containing org. solution by using a selectively permeable membrane with org. solvent resistance to membrane separation treatment to concentrate a resin without denaturing the same.
CONSTITUTION: An org. solution containing a resin such as a paint or the like is contacted to a selectively permeable membrane comprising a polymer such as a polyimide or the like with org. solvent resistance under a pressure of 5W25kg/cm2 generally. By this treatment, a transparent permeated liquid not containing the resin substantially is obtained. The resulting recovered permeated liquid, that is, an org. solvent can be utilized as a permeated liquid of the permeable membrane without necessitating phase change. Further, because the dissolved resin is concentrated in a form being not denatured, it can be directly reutilized.
