Dehydration operation is one of the most important operations at the gas refinery that can be set through the gas dew point. Absorbent material in terms of business groups, bauxite, alumina, gels, activated carbon and molecular sieves are divided. Zeolites in this category because of the reasonable prices, good thermal stability, good chemical stability, mechanical stability is acceptable, high specific surface area and acidity levels in the oil and gas industry can be used as absorbent. Zeolite crystals that have good thermal stability, are very active. The simulation using the Aspen Hysys software performance molecular sieve zeolite Dehydration unit 104 refinery in South Pars Phase 19 was carried out. In order to collect field data simulation process and the influence of various parameters on the performance of zeolites were investigated
