Abstract :
This study evaluates the effect of Structural modifications on energy consumption of gas treatment units of BIDBOLAND refinery (Iran’s first gas refinery). To this aim, Aspen HYSYS (V.8.3) software was employed for the unit simulation in rate based method. The results show that as CO2 content in inlet sour gas is less than 2 percent and MDEA solution is used as solvent, using multiple feeds to the absorption column, static mixers and absorption column sidestream cannot reduce energy consumption level; while using desorption column sidestream and a flash unit can reduce the unit energy consumption up to 10 percent.
