چکیده:

Gas permeation behavior through a type of polymeric membrane is investigated in this work. The main objective of our study was to determine acid gas permeation properties of a specific polymeric membrane over a range of operating temperatures and pressures. Diffusive layer of this membrane consists of polyesterurethane urea and demonstrates high chemical stability in corrosive media. Permeances were determined at temperatures 35-55 o C, and pressures 10, 20 and 30 bar for methane, carbon dioxide and nitrogen. Selectivities were also determined for actual binary mixtures of CO2/CH4 and H2S/CH4.
