Abstract: Disclosed herein is a process for carrying out an ion exchange process which involves providing two interacting sets of banks of continuously stirred tank reactors (CSTR's) each containing a bed of ion exchange resin and causing the resin to move in one direction through each bank of reactors and the feed solution and/or or eluant in the opposite direction. In carrying out the process, a feed solution is introduced in a first reactor causing dissolved ions to be captured on the resin, eluant is introduced into a reactor upstream of the first reactor in the direction of resin movement causing ions captured on the resin to be removed into the eluant and eluant rich in ions removed from the resin will be taken from a reactor upstream of the reactor in which the eluant was introduced, for further processing. Thus, in this form of the invention there is, in effect, a loading bank of reactors in which ions from the feed solution are captured followed by a regenerating bank of reactors in which the eluant removes the ions captured on the resin and regenerates the resin.

Abstract translation: 本文公开了一种用于进行离子交换过程的方法，该方法涉及提供两个相互作用的连续搅拌釜式反应器组（CSTR's）的组，每组含有离子交换树脂床，并使树脂在一个方向上移动通过每一组反应器 和进料溶液和/或洗脱液在相反方向。 在进行该方法时，将进料溶液引入第一反应器中，使溶解的离子捕获在树脂上，将洗脱液沿着树脂移动的方向引入第一反应器上游的反应器，导致在树脂上捕获的离子为 从洗脱剂中除去富含离子的离子的洗脱液将从其中引入洗脱剂的反应器上游的反应器中取出，以进一步处理。 因此，在本发明的这种形式中，实际上存在一个反应​​器的装载组，其中捕获来自进料溶液的离子，随后再生一批反应器，其中洗脱剂除去捕获在树脂上的离子并再生树脂 。
