Gas Separation using Acrylonitrile Butadiene Styrene Membrane

This report is discussing mainly about the permeation of gases using Acrylonitrile Butadiene Styrene (ABS) membrane. ABS is chosen because its cost and properties that made it suitable for gas separation. In this project, focus is given fabrication of the said membrane and permeation experiment on the membrane. The gases which are used for the study is CH4, O2 and N2. Two types of membrane are fabricated in the studies which are porous and dense. Solution-casting technique is used to fabricate dense while porous membrane is fabricated by phase inversion (solution precipitation). The membranes are tested for its permeability for the three gases using Gas Permeability Test Unit. Based on the result, dense membranes have better ideal selectivity compared to the porous membrane. The result obtained will be useful in determining the potential of ABS as membrane for gas separation.
