Abstract

Gas transfer through a composite has been studied. The main parameters affecting the membrane permeability have been determined. It has been shown that, in the presence of a viscous flow of a gas through a porous support, its flow rate through the composite membrane depends on the direction of transfer. The intensity of this effect increases with an increase in the support resistance to the Knudsen flow and decreases with reduction in the support resistance to the viscous flow or a decrease in the pressure drop across the membrane. It has been found that, in the presence of the asymmetry effect, the gas flow rate through the composite membrane is lower when the gas is transferred from a selective layer to a support.

气体通过复合膜的不对称传递

摘要

已经研究了通过复合材料的气体传输。已经确定了影响膜渗透性的主要参数。已经显示出，在通过多孔载体的粘性流的存在下，其通过复合膜的流速取决于转移方向。该作用的强度随着对努氏流的支撑阻力的增加而增加，并且随着对粘性流的支撑阻力的减小或跨膜的压降的减小而减小。已经发现，在不对称效应的存在下，当气体从选择性层转移到载体上时，穿过复合膜的气体流速较低。
