Zusammenfassung:The present invention relates to a system and method for removing solvents, such as water, from fluids. An electrochemical system has a first reservoir receiving a feed stream. The feed stream contains a solvent and a solute different from salts. A second reservoir receives a brine stream having a higher salt concentration than the feed stream. An electrode contacts a loop of redox-active electrolyte material, which causes a reversible redox reaction. The positive reaction causes the loop to accept first ions from the salt in the first reservoir and direct second ions into the brine stream in the second reservoir. Three alternating ion exchange membranes define the first and second reservoirs. A concentrate stream is discharged from the first reservoir, and the concentrate stream has a second solute concentration greater than a first solute concentration. 전기화학 시스템은 공급물 스트림을 수용하는 제1 저장소를 갖는다. 공급물 스트림은 용매 및 염과 상이한 용질을 포함한다. 제2 저장소는 공급물 스트림보다 더 높은 염 농도를 갖는 염수 스트림을 수용한다. 전극은 가역적 산화환원 반응을 일으키는 산화환원 활성 전해질 재료의 루프와 접촉한다. 반응은 루프가 제1 저장소의 염으로부터 제1 이온을 수용하고 제2 저장소의 염수 스트림으로 제2 이온을 유도하도록 한다. 교번형 3개의 이온 교환 멤브레인은 제1 및 제2 저장소를 정의한다. 제1 저장소로부터 농축물 스트림이 배출되고, 농축물 스트림은 제1 용질 농도 초과의 제2 용질 농도를 갖는다.
