One of the main and common processes for deleting acid gases(H2S,CO2) is using amino solvents. This research attempts to modeling and evaluation of pressure and temperature parameters for two hydrated solvents (DEA,MDEA) with aspen hysys software. The obtained results of simulation to sure gas in purification unit in gas regions Iran for both of solvents. Obtained results of better function of MDEA process compared with process for selective absorption, reducing consuming energy of purification unit, reducing investment costs in solvent and reclamation unit and decreasing equipment corrosion. According to obtain results, suggests that co-absorption acid gases with amino- processes with combination of two solvents: MDEA and DEA
