Failure Analysis and Fault Diagnosis of molecular Sieve for natural Gas Dehydration
Molecular sieves are one of the most promising processes for natural gas dehydration,but there is a serious problem with this process,which is that the dehydration ability of molecular sieves will sharply decrease with increasing use time.Through a series of experimental studies on pH value,thermogravimetric analysis,differential thermogravimetric analysis,scanning electron microscopy,etc.,the results show that there are four reasons for the failure of molecular sieves:surface alkalinity is destroyed;Grain size increases and agglomeration occurs;Alcohols,ethers,and sheep carbon based sulfides are generated within the pores.
