Mathematical modelling and numerical study of recirculation membrane and membrane-refrigerated systems of compressed air dehydration

Abstract

Abstract Mathematical modeling and numerical investigation of the process of drying compressed air was carried out in a hybrid membrane-refrigeration system, which consists of a compressor with a receiver, a Peltier refrigerator, and a gas separation membrane module. This system allows you to get dry air, dried to a dew point of -50°C and below without loss of compressed air since only condensed water is removed from the system. It is shown that reduced energy consumption decreases with increasing compression pressure. A comparison of the hybrid membrane-refrigerator system with a single-module membrane system has been carried out, the advantages of the hybrid system are shown.
