摘要： A liquid-liquid extraction system including an outer chamber and an inner chamber or two opposed frames separated by a membrane. The outer chamber is adapted to contain one of a feed solution and a liquid extractant and defines a containment region. The inner chamber is adapted to contain the other of the feed solution and the liquid extractant within a lower portion of the inner chamber. The inner chamber is defined by a microporous membrane sleeve that internally maintains a frame. Upon final assembly, at least the lower portion of the inner chamber is positioned within the containment region of the outer chamber such that the microporous membrane sleeve establishes an extraction interface between contents of the inner and outer chambers. In one embodiment, the flow region of the microporous membrane sleeve is immersed within a feed solution otherwise contained within the outer chamber.
摘要翻译：一种液体 - 液体萃取系统，其包括由膜隔开的外室和内室或两个相对的框架。外室适于容纳进料溶液和液体萃取剂中的一种，并且限定了容纳区域。内室适于将另一种进料溶液和液体萃取剂容纳在内室的下部内。内室由内部保持框架的微孔膜套筒限定。在最终组装时，至少内室的下部位于外室的容纳区域内，使得微孔膜套筒在内室和外室的内容物之间建立提取界面。在一个实施例中，微孔膜套筒的流动区域浸没在另外容纳在外部室内的进料溶液中。

摘要： Liquid-liquid extraction elements are described. A liquid-liquid extraction element includes a first layer pair and a second layer pair disposed adjacent the first layer pair forming a stack of layers. The first layer pair includes a first polymeric microporous membrane, and a first flow channel layer oriented in a first flow direction having a fluid inlet and a fluid outlet disposed on first opposing sides of the extraction element. The second layer pair includes a second polymeric microporous membrane and a second flow channel layer oriented in a second flow direction different than the first flow direction and having a fluid inlet and a fluid outlet disposed on second opposing sides of the extraction element. The first microporous membrane is disposed between the first flow channel and the second flow channel. Methods of extracting a dissolved solute from a first liquid to a second liquid are also described.
