| 摘 要： | 以疏水性聚丙烯中空纤维膜为气液膜接触器，n-甲酰吗啉水溶液为吸收剂，研究了膜气体吸收工艺分离C6H6/N2的传质过程. 在非润湿条件下，建立了膜气体吸收C6H6传质微分模型，模拟了C6H6在疏水性聚丙烯中空纤维膜管程及膜孔内的传质过程，并对C6H6的吸收速率进行预测. 结果表明，在实验条件下，膜气体吸收C6H6的速率为(0.89~6.13)′10-2 mg/(m2×s)，微分模型对吸收速率预测的平均误差为1.9%，能准确描述中空纤维膜吸收C6H6的过程.

| Abstract: | A membrane based gas absorption process for the separation of benzene(C6H6) from C6H6/N2 mixture gas was studied.The aqueous solution of n-formyl morpholine was used as absorbent and hydrophobic polypropylene hollow fiber membrane as gas-liquid contactor.For non-wetted mode,a differential model was presented to simulate the mass transfer process of C6H6 in the tube side and membrane pore of hollow fiber.The values of C6H6 absorption rate were also predicted to compare with experimental values.The results sh... |
