commercial membranes. In addition, only few studies regarding MMMs approach for enhanced C3+ heavy hydrocarbons removal from natural gas are reported in the literature. More research efforts are needed in the future from the selection of right nanofillers and understanding the dynamic interactions between polymers and nanofillers regarding mixed gas permeation in the membrane matrix.

The permeation properties of the polymeric and mixed polymer matrix membrane materials have been reviewed and compared under varying operating parameters by many research groups. These results emphasize the observation that C3+ hydrocarbon separation performance is strongly related to the testing condition, feed compositions and chemical structures. However, a thorough evaluation of C3+ hydrocarbon separation properties is rarely reported in the literature under industrially relevant feed streams and testing conditions. Thus, there is a need for further research and testing of advanced membrane materials that are resistance to swelling and satisfy the practical requirements during the actual industrial gas processes.
