The key parameter dictating the selection of membrane material for acid gas removal applications is the membrane's selectivity, which is the ratio of the permeability of the desired acid gas (H2S or CO2) to the permeability of methane (CH4) or other valuable hydrocarbons. Membrane separation processes rely on the principle that different gases permeate through a membrane material at different rates. Permeability is a measure of how easily a gas passes through the membrane. Selectivity is the crit....
