Abstract：Pressure swing adsorption(PSA)oxygen generator is a device for gas separation based on the principle that oxygen molecular sieve has different adsorption rates of oxygen and nitrogen under different pressures.It has the characteristics of flexibility,intelligence,and energy saving in the operation of process equipment.Molecular sieve,as a key medium in the process of PSA,has a significant impact on efficiency and purity of oxygen production,and service life of oxygen generators.This paper introduces the process flow of oxygen generators,the types and performance characteristics of molecular sieve in oxygen generators,discusses the essential causes of molecular sieve failure,analyzes the factors affecting molecular sieve failure,and elaborates on how to improve the service life of molecular sieve.
