Abstract: With the further improvement of the national requirements for energy conservation and environmental protection,natural gas is widely used as an environment-friendly energy. Natural gas treatment is an important link in the natural gasproduction process. Its product quality directly affects the use of downstream equipment or users. In the natural gas treatment process,molecular sieve dehydration equipment is an important production equipment in the process system. The effect of molecular sieve dehydration will directly affect the product quality of natural gas. The reasons for the performance decline of molecular sieve dryer are comprehensively analyzed and treatment measures are proposed,so as to provide reference for other molecular sieve users.

Key words: molecular sieve, adsorbability, grating deformation, deterioration of molecular sieve
