Calculation of the degree of separation for a membrane module at the low permeability of the purified gas through the membrane

The calculation of the degree of separation for a low-permeable impurity in a membrane module at a low permeability of the purified gas through the membrane was carried out. It was shown that the dependence of the degree of separation on the permeability of the purified gas at its constant sampling rate is extreme. Such a character of the dependence in the membrane module will also influence the value of the degree of separation of hybrid processes, for example, absorbing pervaporation.
