摘要
建立了水蒸气在中空纤维复合膜中渗透的微分阻力模型,用实验验证了模型的可靠性。采用该模型估算出中空纤维膜的结构参数,研究了水蒸气在各层膜中的阻力,并以H2O/C2H2系统为例,考察了膜的结构参数对H2O/C2H2选择性的影响。
A differential resistance model was established to describe the permeation of water vapor across the hollow fiber composite membrane. The reliability of the model was verified by experiment. The configuration parameters of the hollow fiber membrane employed in the experiment were calculated with this model. The resistance of each layer to water vapor was also studied. The influences of membrane configuration parameters on selectivities of H2O/C2 H2 were discussed.
