the mass transfer effect of ma when using absorption solution is better than using vacuum-pumping and sweep gas .
一般采用吸收式膜吸收法的传质效果要优于减压式和吹扫式膜吸收法的传质效果。
in this paper , the necessary of sweep gas , the ratio of water versus oxygen of the feed gas as well as its pressure are studied to examine their effects on separation process.
