Abstract

Natural gas usually contents several of non-hydrocarbon components for example, hydrogen sulphide, carbon dioxide and water vapor. Moreover, these components are undesirable and cause several technical problems for instance, corrosion and pollution. Indeed, chemical solvent gas sweetening process may be considered the most popular technology to remove acid gases from natural gas stream [1]. However, this process may face several technical problems during its operation for example, amine carry over and pressure dropping in the amine absorber. Therefore, this study aims to simulate gas-sweetening process at North Gas Company (N.G.C.) as a case study using Aspen HYSYS simulator program. The laboratory analysis has shown that the gas at the NGC possesses huge amounts of H2S (about 2.95%) and CO2 (about 2.54%). The simulation work has examined the effects of declining amine contactor pressure on the sweetening process performance and rich amine loading. Moreover, the simulation study has been found that when the amine contactor tower declines that will effect acid gases loading in amine solution.
