Abstract	The present work is focused on gases high purification from unreadily permeating impurities by one-compressor multistage membrane apparatus (OMMA). It looks like a simple one way membrane cascade, consisting from several membrane modules with only one compressing point. In this operating regime the pressure of high pressure cavity is decreasing from one to another while the concentration of high penetrating component is increasing. The equation of purification degree calculation was obtained. It shows how the impurity concentration of permeate reduces in comparison with initial concentration of flow (feed flow), incoming to the membrane module or apparatus. The equation for purification degree calculation was obtained. For the case of low impurity concentration there was leaded the comparison of calculated and experimental (from patent) data. The dependence of purification degree on the number of membrane modules composed apparatus which has an extremum was shown.The description of one-compressor multistage membrane apparatus was determined.
