In this study, sour gas sweetening plant with amine solution has been simulated using by Promax software and the process parameters is studied. The studied unit is Iranian Offshore Oil Company is selected for the simulation and optimization. The process parameters that affect energy consumption and quality of sweet gas production at low amine (Lean Amine) entering the absorption tower, the level of circulating amine (Amine Circulation Rate), the concentration of amine (Amine Concentration), the temperature of the feed gas entering the tower adsorption, absorption tower and the tower regeneration pressure, flow rate or temperature of the steam used in the reboiler of the tower regeneration tower are restoring. The obtained results in this work show that Amonia concentration in sour gas is an important parameter in this plant. Also results show that the PROMAX software can produce more reliable data in comparison with HYSYS software.
