Development of PES-SAPO Amine Mixed Matrix Membrane for Carbon Dioxide Removal

Purification of natural gas by removing carbon dioxide is the most important step
before the gas can be on sale. The aim of this study is to develop SAPO Amine based
mixed matrix membrane (MMM) for the removal of carbon dioxide from raw natural
gas. This was carried by the blending of SAPO with amine in polysulfone. The
membrane was developed by varying the percentage of amine from 10wt% to 20wt%.
Characterization showed that the SAPO-amine membrane was dense and the SAPO
was distributed homogenously. The performance showed that the highest ideal
selectivity was achieved by the addition of amine with 10wt%.The expectation from
this study is to able to develop Mixed Matrix Membrane (MMM) for carbon dioxide
removal from raw natural gas. In this paper, the material selection , membrane
fabrication and performance test were also discussed.
