Abstract
Pressure swing adsorption is the feasible method for nitrogen and methane separation in the oilfield associated gas .The adsorption isotherm of nitrogen and methane on the activated carbon WHXR-LB20 were determined by gravimetric method .The separation coefficient was 2 .87 ,which could satisfy the demand in industrial application .The activated carbon had good regeneration effect to nitrogen and methane .T he effects of ethane ,propane and n-butane in the oilfield associated gas on WHXR-LB20 were determined .The results showed that the activated carbon has good regeneration effect to the ethane and propane . But the n-butane accumulated on the WHXR-LB20 . The accumulation amount reduced the saturated adsorption capacity of nitrogen and methane on the activated carbon WHXR-LB20 .关键词
