    Abstract： For special natural gas reservoirs with high carbon and micro H2S， more and more attention has been paid to Selexol decarburization process due to less its corrosivity. Adopted is the software HYSYS 2006 to optimize absorber control parameters and flash regeneration conditions of the Selexol decarburization process and reflected further is adaptability of the process. Research results show that the lower of injection temperature the better when the absorption tower operating condition is the feed gas temperature at the tower inlet： -5 to 5℃ and lean liquid injection rate is about 750 m3/h but the temperature shall not be below -18℃ in actual operation. The optimized pressures at 3 stages are 2400， 500， and 50 kPa respectively during flash regeneration. The Selexol decarburization process is be suitable for decarburization treatment of lean gas with CO2 content less than 60 % and C4+ heavy hydrocarbon less than 1 % （α）.
