    • A multistage countercurrent separation apparatus and method is described. Each stage includes a mixer zone (M) and a settler zone (S), both of which have temperature control means to achieve a first temperature in the mixer zone and a seoond temperature in the settler zone. Solvents used in the process are selected so that they have at least one immiscibility transition temperature such that they form a single homogeneous phase at said first temperature and two heterogeneous phases at said second temperature. By carrying out the process, a solute or solutes introduced into the system may appropriately be efficiently concentrated or separated with minimal agitation. Furthermore, because emulsification by rapid agitation is avoided, the homogeneous phase quickly coalesces upon passing into the heterogeous phase, thereby increasing the throughput which may be achieved by the extraction process.
    • 描述了一种多级逆流分离装置和方法。 每个阶段包括混合器区(M)和沉降器区(S),两者都具有温度控制装置,以在混合器区域中实现第一温度和在沉降器区域中的seoond温度。 选择在该方法中使用的溶剂使得它们具有至少一个不混溶转变温度,使得它们在所述第一温度下形成单一均相,并在所述第二温度下形成两个非均相。 通过进行该方法,引入到体系中的溶质或溶质可以以最小的搅拌有效地浓缩或分离。 此外,由于避免通过快速搅拌的乳化,均匀相通过异质相后快速聚结,从而增加通过萃取过程可达到的生产量。
