摘要： A method of solvent extraction that reduces crud formation, and generally comprises the steps of: providing an organic solution; providing an organic-soluble antioxidant; and, dissolving the antioxidant in the organic solution, thereby reducing crud formation. Antioxidant levels within the organic solution may be monitored and adjusted over time to maintain proper levels of antioxidant. A solvent extraction circuit for the reduced formation of crud is also disclosed. The circuit generally comprises at least one mixer, a first settler; and, delivery means for providing an organic-soluble antioxidant to one or more portions of the at least one mixer and/or the first settler. The circuit may comprise an emulsion zone removal means for speeding up flow rates in the first settler, and at least one second settler may be operatively connected to the emulsion zone removal means to process the removed emulsion separately and differently than the first settler.

摘要： In a mixer settler apparatus, coalescing media are disposed within a structure, which structure forms a mixed-liquid transmission flow path that extends between an outlet of a mixing tank and settling tank and which structure and path may include at least one auxiliary tank. The coalescing media may include particulates, woven wire mesh, knitted wire mesh, interwoven layers of metal and plastic strands, and/or various other structured media such as layers of hydrophobic plastic media alternating with layers of hydrophobic plastic media coated with a thin layer of hydrophilic material.
摘要翻译：在混合器沉降器装置中，聚结介质设置在结构内，该结构形成在混合罐和沉淀槽的出口之间延伸的混合液体传输流动路径，并且哪个结构和路径可以包括至少一个辅助罐。聚结介质可以包括微粒，编织丝网，针织丝网，金属和塑料线的交织层，和/或各种其它结构化介质，例如与疏水性塑料介质的层交替的各种疏水性塑料介质，所述疏水性塑料介质涂覆有薄层亲水材料。
