Separation mechanism of dissolution-diffusion of gas through non-porous membrane, i.e., dense membrane (such as polymer membrane). At this time, the process of gas passing through the membrane can be considered to be composed of three steps.(1) adsorption process, that is, the gas on the upstream surface of the film is adsorbed, condensed, dissolved.This process is somewhat selective.(2) diffusion process, that is, the adsorbed gas in the membrane on both sides of the pressure difference, concentration difference, according to the different diffusion coefficient diffusion through the other side of the membrane.(3) desorption process, that has been diffused through the gas in the film downstream surface desorption, stripping process.
