Abstract

BACKGROUND: Gas drying is widely used in many applications of science, technology and industry: high-purity gas media (microelectronics), and its methods are constantly being improved. One of them, membrane separation of gases, although considered as one of the most promising, is currently understudied.

AIM: The purpose of this work is to show the possibilities of the membrane gas separation method when it is used for drying compressed gases.

METHODS: The results of the study of the drying of compressed gases were obtained using the membrane method of gas separation.

CONCLUSIONS: The dependence of the degree of drying (dew point temperature) on such parameters of the gas separation process as the relative pressure drop across the membrane, the permeability and selectivity of the membrane for water vapor, the value of the working pressure and the value of the dried gas flow per unit area of the membrane is shown. It is shown that, with the help of membrane gas separation, drying can be performed to a dew point temperature of –100 ˚С and below. On the example of drying air and methane, the conditions are given under which membrane drying can be energetically more profitable compared to drying by cooling.
