Liquid membrane modules with minimal effective membrane thickness and methods of making the same. |
摘要 |
<p>Modules for use in fluid separations, especially contained liquid membrane separations, exhibit minimal effective membrane thickness. The modules [10] have a module case [C] and a bundle [B] of a dense plurality of hollow fiber membranes [Ff,Fs] contained in the case. One set of the fiber membranes [Ff] in the bundle [B] constitutes feed-fibers while another set of the fiber membranes [Fs] in the bundle constitutes strip-fibers for use in contained liquid membrane separations. The feed-fibers [Ff] and strip-fibers [Fs] are disposed within the elongate module case in opposite generally wave-like paths such that the feed-fibers and strip-fibers converge at generally lengthwise-separated crossing regions [CR] within the module. This disposition of the feed-fibers and the strip-fibers minimizes the effective membrane thickness value of the module as compared to conventional contained liquid membrane modules thereby enhancing the efficacy of fluid separations. <IMAGE></p> |
