PERVAPORATION PROCESS AND ASSEMBLY

摘要

The invention is a pervaporation process and pervaporation equipment, usi ng a series of membrane modules (102 to 105, 204), and including inter-modul e reheating of the feed solution under treatment. The inter-module heating i s achieved within the tube or vessel (101, 201) in which the modules are hou sed, thereby avoiding the need to repeatedly extract the feed solution from the membrane module train.
