Abstract
Among the popular and important processes to remove the acidic gases (hydrogen sulfide and carbon dioxide) is using amine solvents.The duty of gas refinery unit, besides the separation of acidic gases from the natural gas, is also controlling the dew point of water and hydrocarbons in the output gas. Selection of suitable processing conditions in gas refinement unit to reach the standard characteristics of sweet gas significantly affects on the operation costs. Present study has simulated the gas softening unit of Sarakhs refinery using Aspen Hysys software with MDEA aqueous solvent to optimize the concentration, MDEA solvent's flow stream and thermal load of restoration unit and other processing conditions. Results indicate that the optimum performance of MDEA solvent is 45–50% wt concentration at 55–63°C.According to the input feed flow and market demand, solvent concentration and input solvent's temperature vary in above-mentioned efficiency. As well, in present study, the effect of temperature, flow stream and concentration of input solvent on contactor and other processing sections is discussed.
