Dehydration process based on hollow fiber composite membrane is one of thecrucial and effective methods to remove water vapor from industrial gases such aslight hydrocarbon, compressed air, natural gas and so on. Dehydration of propylenewith VP method was studied in the thesis. We prepared the PVA/PS、CS/PS andPVA-CS/PS hollow fiber composite membranes by spread method. The permeationbehavior of water vapor among coagulable light hydrocarbons through compositemembranes and asymmetric membrane was researched by vapor permeation method.Also a differential mathematical model was established which can describedehydration of gas phase propylene.
