Development of polysulfone/polyetherimide blend membrane for removing carbon dioxide from methane

Monitor of high CO2 content natural gas is very important issue. The content of CO2 in the natural gas will cause the lower of calorific value which effects to the value of the oil. In order to remove CO2, membrane is one of the best options in term of economy. However, the membrane has low selectivity and is not able to apply in industry. The development membrane selectivity is necessary. During this project, two materials used are polysulfone and polyetherimide. The main objective for this study is to develop polymeric membrane for removal of high CO2 at the platform. The method used for drying is solvent evaporation. After drying process, the membrane needs to be characterized. The synthesized membranes will be used for the performance test by using pure CO2 and CH4 gases. The outcome of the project is a membrane which has high selectivity to remove CO2.
