Effect of fiber variation on the performance of countercurrent hollow fiber gas separation modules

摘要: Abstract A theoretical and experimental study of the effects variable fiber properties on countercurrent hollow gas separation module performance is presented. Variations in ID, slow permeance, selectivity are considered. Variability any these detrimental to performance. The drop increases as either property variation or product purity increase, but permeate mixing can improve Fibers with higher permeation feed rate ratios may stop producing a retentate consume from other fibers. theory agrees well experiments for production nitrogen air.
