Abstract

Natural gas may consider the most popular energy source in recent era and the demand for it in recent years has been dramatic. However, natural gas is existed in deep reservoirs so it may contents many impurities for instance, hydrogen sulphide, carbon dioxide and mercury. Indeed, these impurities may cause several technical problems for instance, corrosion and environment pollution. Therefore, raw natural gas should be purify before processing it to global gas markets and amine gas sweetening process may consider the most common technology to remove acid gases from natural gas stream. Thus, this study aims to treat a given composition natural gas stream with a moderate hydrogen sulphide contents about 2500ppm vie engineering mathematical calculations for MEA circulation rate that was about 490 gpm. The amine circulation rate is considered quite important amine gas sweetening parameters that should be at optimum value to achieve optimum acid gas removal and meet the product requirement. Thus, the amine circulation rate examined by material balance calculations for amine contactor tower. As a result, it is found that 490 gpm amine circulation rate is an effective value to reduce hydrogen sulphide contents to 4ppm which it meets the gas pipelines and gas sell contracts specification.
