Abstract
Natural gas is an important resource that ensures the energy supply and reduces CO2 emissions simultaneously. However, many natural gases from well head contain a certain amount of acid gas, which must be removed to meet the pipeline requirement. Among the existing natural gas sweetening process, membrane technology is considered as a cost-effective, less energy intensive method that can remove both CO2 and H2S simultaneously. The membranes with high permeability, high selectivity, and good durability are developing very fast. In this review, we summarized the latest state-of-the-art membranes investigated for H2S/CH4 and CO2/CH4 separation applications, including conventional polymer membranes, polyimides, polymer of intrinsic microporosity, rubber polymers, carbon molecular sieve membranes, hollow fiber membranes, and membrane processes for H2S and CO2 removal from natural gas.
