运用并实验验证了描述气体膜分离速率的串联阻力模型.该模型表明，膜两侧传质阻力总是使膜分离器的实际分离系数小于膜的理想分离系数.对于渗透速率较高的膜,为提高膜分离器的实际分离系数，应尽量增大膜两侧（特别是高压侧）的传质速率. The model of series resistance, which describes the separation rate of gas membrane, was validated experimentally.The model shows that the mass transfer resistance on both sides of the membrane always makes the actual separation coefficient of the membrane separator less than the ideal separation coefficient of the membrane.For the membrane with higher permeation rate, In order to improve the actual separation factor of the membrane separator, the mass transfer rate on both sides of the membrane (especially on the high pressure side) should be increased as much as possible.
