摘要： The invention provides a process and apparatus for liquid-liquid extraction in which a first liquid phase is passed continuously through a series of extraction stages (10) whilst a second liquid phase is passed continuously through the series in counter-current to the first phase. In each stage the second phase is dispersed as by a sieve plate (11) and then allowed to coalesce into a settled body (14) from which the second phase is withdrawn and passed to the next adjacent stage. The invention is characterised by the fact that the flows of the two phases in each stage are generally transverse to each other. Preferably the first phase flows through the series of stages under gravity whilst the second phase is pumped (16) from stage to stage to control its inter-stage transfer.
The invention combines the features of separate control of residence time characteristics of an extraction column with the safety aspects inherent in a mixer/settler battery.

摘要翻译： 本发明提供了一种用于液 - 液萃取的方法和装置，其中第一液相连续通过一系列萃取级（10），而第二液相连续通过该系列与第一相逆流。 在每个阶段中，第二阶段通过筛板（11）分散，然后使其聚结成沉降体（14），第二阶段从该平台取出并传递到下一相邻阶段。 本发明的特征在于，每个阶段中的两相的流动通常彼此横向。 优选地，第一阶段在重力作用下流过一系列阶段，而第二阶段从阶段泵送到阶段以控制其阶段间转移。 本发明将提取塔的停留时间特性的单独控制的特征与混合器/沉淀池电池固有的安全方面相结合。
