针对凝液回收的浅冷结合膜分离法,通过调节压力、温度、膜面积等参数来优化回收率,并使用化工软件Pro/Ⅱ进行流程模拟,当浅冷温度为-29℃、膜渗透侧压力为120 k Pa、膜面积为160 m^2时,可以得到较高的回收率为97.2%。此工艺能在达到更高收率的同时一定程度地降低装置功耗,具有更好的实际应用价值。
Injecting air catalytic oxide production process,which has various production mechanism,is an innovative,efficient,and lower cost technology of enhance heavy oil recovery.So it is more and more concerned by people.Using the copper naphthenic as the catalyst,this paper focuses on evaluation of catalytic conditions for SZ36-1 heavy oil.When catalyst dosage is 0.2(w)%,reaction temperature is 100℃,air pressure is 2MPa and reaction time is 3d,oxygen dosage of tail gas was reduced from 21.0% to 10.0% and acid number of heavy oil was raised from 3.96mgKOH/g to 13.50mgKOH/g and viscosity was raised from 2.004Pa·S to 11.48Pa·S.When oxidized oil was added 1.2(w)% SW-1 additive and 40(w)% water,stirring was operated under constant temperature,O/W emulsified oil was generated,and viscosity was finally reduced to 0.067Pa·S and the total ratio of reduced viscosity was 96.66%.
