CROSS-FLOW MEMBRANE MODULE

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.
