| Abstract: | The separation of He-CH4 and He-CH4-N2 gas mixtures were accomplished with single-membrane permeators housing asymmetric hollow fibers of cellulose acetate (CA), two-membrane permeators enclosing both CA membrane and symmetric dense capillaries of sili-cone rubber (SR). The effects of the relevant parameters-e. g. permeate pressure ratios, stage cuts,et al. and flow pattern have been studied. Mathematical models describing asymmetric permeators were further discussed. |
