Abstract

Acid gas removal process, which is also known as sweetening process, is considered a very important industrial operational process which has taken place in many works. The main idea of this process is based on absorption, and the selection of the solvent is mainly based on its capability of removing acid gases from the feed gas such as carbon dioxide (C02) and hydrogen sulphide (H2S). Such acid gases found in the gas can cause operational problems like corrosion and equipment plugging. The solvent used for the absorption processes to sweeten the natural gas is classified into two types which are chemical and physical absorption. The most used absorption processes for sweetening the natural gas are using the chemical solvents such as alkanolamines or "amine". In this context, diglycolamine (DGA) is used in the aqueous solution to remove the acid gases from natural gas stream. In this research, existing process flow diagram of industrial Acid Gas Removal Unit (AGRU) will be modified in terms of solvent composition· used in the absorption process. Manipulating the ratio of solvent to moisture content in the solvent solution will replace the existing solvent composition. Simulation using Aspen Hysys is then performed to parameters, which are absorption colunm removal efficiency, power consumption, heating duty and cooling duty. The simulation results are expected to show improvement to the existing AGRU system used at ELNG (Egyptian Liquefied Natural Gas Company).
