摘要：

采用实验室自制的聚酰亚胺中空纤维膜，系统考察了原料侧放空气流量、原料气压力、温度、组成、膜丝填充率等参数对油田伴生气中CO2分离效果的影响。实验结果证明原料侧放空气流量对整体分离性能影响最为显著；升高原料气压力会增加处理量但对分离性能无明显影响；升温导致渗透加速但是分离性能有下降趋势；原料气中CO2浓度变大导致膜的渗透速率随之变大；50%装填率表现出了最佳的分离效果。在580小时测试过程中聚酰亚胺膜渗透分离性能较为稳定。这些结果揭示了相关参数对该分离过程影响的规律，并验证聚酰亚胺中空纤维膜用于油田采出气中CO2分离回收的可靠性。

By using the self-made polyimide hollow fiber membranes, influence of released gas flowrate on feed side, feed gas pressure, temperature, composition and fiber packing density on CO2 removal performance from oil field associated gas was systematically investigated. The experimental results showed that released gas flowrate on feed side has the most significant influence on overall separation performance; feed gas pressure directly determines the treatment capacity but has no obvious effect on the separation performance; increased feed gas temperature leads to better permeation but declined separation performance; increase of CO2 concentration in feed gas leads to increased permeation flux; 50% fiber packing density has been proven to be the best choice. The permeation and separation performance of polyimide membrane was quite stable during the long duration test of 580 hours. These results have revealed the influence rules of related parameters on this separation process and verified the reliability of polyimide hollow fiber membrane for the separation and recovery of CO2 from oil field associated gas.
