Organic Vapor Dehydration Membrane Module

UBE organic vapor dehydration membrane modules (vaporpermeation) have polyimide hollow fiber membranes originated from UBE. The modules that water vapor permeates preferentially than organic vapors can recover organic vapors by separating water vapor efficiently. Bioethanol has been attracted much attention as renewable energy and raw material of renewable chemicals. The modules are applied to a lot of plants all over the world from 1990's. The modules also have been applied to purified processes of isopropanol and methyl ethyl ketone.
