In recent decades, due to its importance for the simulation of sweetening units are taken into consideration . Natural gas often contains impurities such as carbon dioxide and hydrogen sulfide items within the gas, acid gas or sour gas is highly toxic and that they in turn can lead to corrosion of pipes and devices Hence, it must be purified before use of natural gas, ie the impurities such as carbon dioxide and hydrogen sulfide and other acid gas components can be separated and so sweet The removal of acid gases in the oil, gas & petrochemical is a very important These gases are usually by some physical or chemical solvent absorption towers, can be absorbed Alkanolan aqueous amines such as DGA and MDEA, DEA, MEA solvents commonly used in the process are important items within the natural gas sweetening In this paper, H2S and CO2 solubility in the solvent mole-time DEA, MDEA and also combinations of temperature and pressure is measured absorption tower refinery. And the absorption tower refinery using HYSYS software accurately simulated and the results for selected vehicle with real data are compared with each other and the .
