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