Application of mixed charge of molecular sieve dehydration and demercaptan process in Amu River natural gas treatment plant

This paper describes the dehydration unit of No.1 natural gas treatment plant in Amu River, Turkmenistan. The dehydration and demercaptan process principle and optimal process of two different kinds of molecular sieves mix-filled in different layer of the same adsorption tower are introduced. At the same time, the advantages of molecular sieve applied in deeply dehydration & demercaptan are summarized.
