| 摘 要： | 变压吸附是分离油田伴生气中N_2和CH_4的可行性方法,采用质量法测定了N_2、CH_4在活性炭WHXR-LB20上的吸附等温线,分离系数为2.87,满足工业应用要求且再生效果好;同时测定了油田伴生气中C_2H_6、C_3H_8,n-C_4H_(10)等对WHXR-LB20的影响,结果表明,C_2H_6、C_3H_8在WHXR-LB20上再生效果很好,而n-C_4H_(10)在WHXR-LB20上有积累,该积累量使N_2和CH_4在WHXR-LB20上的饱和吸附量降低。

| 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. The 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. |
