Abstract

Present invention relates to two-part fluid contactors for application in fluid-fluid contacting processes such as liquid-liquid extraction processes used in nuclear fuel reprocessing. The contactor has a first part and a second part with a plurality of annular regions located between the first and second parts and a plurality of settling compartments disposed sequentially along the axis of rotation of the contactor. First and second fluids are introduced into the annular regions, and a mixture of the first and second fluids is transferred into the settling compartments. The first and second fluids substantially separate in the settling compartments and are then removed therefrom. The apparatus is arranged such that in operation the first and second parts may be moved relatively to one another so that conditions exist in the annular regions such that the first and second fluids disperse one within the other to form a mixture of fluids.
