Use of a Hybrid Membrane–Sorption System with Three Adsorbers for Producing Oxygen-Enriched Air

Аннотация

A three-adsorber ejector membrane–sorption system for separating gas mixtures is proposed for obtaining a product enriched in a weakly sorbable component. The system consisting of a pressure-swing adsorption unit and a hollow fiber membrane module has been experimentally studied for air enrichment with oxygen. Various cyclograms of operation and sorbent regenerating methods have been considered. The efficiency of the proposed system has been compared with that of other systems intended for the same purpose.
