摘要： A continuous extraction system for countercurrent chromatography to achieve continuous solvent extraction, is disclosed wherein two immiscible solvents move in opposite directions through a rotating helical column (11). The coiled tube (11) has two pairs of flow connecting tubes, IF and IC to respectively feed and collect phase 1, and IIF and IIC to respectively feed and collect phase II. Elution of a desired phase takes place by use of a separation device at the head end which selects either the heavier or the lighter phase. This may consist of a suitably weighted suspended outlet tube (18) of Figure 2 in a rotating cylindrical outlet chamber (16) or may consist of a shunt "S" and settling chamber (40 of Figure 6) located outside the rotating part; the heavier phase may be removed from the bottom and the lighter phase may be removed from the top.

摘要： A process for increasing mass transfer coefficients for mass transfer between two fluid phases, one of which is a liquid, is disclosed. The process comprises charging the fluids to an element (9) which has a large interfacial area and which is permeable to the fluids and rotating the element (9) such that the fluids are subjected to an acceleration of at least 300 m sec 2 as they flow through the element (9). The element (9) is mounted conveniently in a rotatable member (2) and the liquid may be collected in a stationary housing (18). The process may be employed in absorption, distillation, extraction. Apparatus in which the process may be effected is also disclosed.
