Abstract :

Abstract Natural gas may contain many of non-hydrocarbon components, for instance, hydrogen sulfide, nitrogen and water vapor. These impurities cause several technical problems such as corrosion and environmental pollution. Therefore, these impurities should be reduced or removed from raw natural gas stream. However, the laboratory analysis has showed that the sour gas has huge quantities of H2S about (5.3%) and CO2 about (4.4%). Indeed, gas sweetening process has been removed in previous study by using Aspen HYSYS. However, sweet gas is still containing some quantities of water reach to more than 23 ppm in sweet gas stream . This amount of water should be removed or reduced . Indeed, water contents in natural gas cause several technical problems such as hydrates and corrosion. Therefore, this study aims at to simulate the prospective gas moisture removal process by using Aspen HYSYS software . Moreover, the simulation process succeeded in reducing the water content to less than 0.1ppm . In addition to that , the simulation approach achieved a process optimization by using several desiccant types such as ,triethylene glycol (TEG) and diethylene glycol (DEG) . Moreover, it investigates also the relationship between absorbent type and its circulation rate with HCs losses from glycol regenerator tower . Keywords: Aspen Hysys applications , Process simulation , moisture removal , Process optimization.
