Solvent extraction and stripping system

Abstract

An apparatus for separating a mixture of two liquids of different densities which liquids are substantially insoluble in one another includes a hollow permeable body having a recess for receiving a first fluid which can flow from the recess through the permeable body to an exterior of the permeable body. A housing surrounds and is spaced from the exterior of the permeable body. The housing has an inlet for a second fluid and an outlet for a mixture of the first and second fluid. A baffle or baffles are provided in the space between the exterior of the permeable body and the housing, and to define a mixing channel in space between the exterior of the permeable body and the housing so that the second fluid can enter the housing inlet and flow through the mixing channel to the outlet, while picking up fluid on the exterior of the permeable body.

1 . A centrifugal separator, comprising a rotatable tank in the shape of a vertical right cylinder in a housing, at least one inlet adjacent a lower end of the housing and a plurality of outlets adjacent an upper end of the housing, and wherein an upper end of the rotatable tank is provided with a plurality of vertical baffles which create a plurality of chambers in the upper end of the rotatable tank. 
     
     
         2 . The centrifugal separator as claimed in  claim 1 , further including one or more additional inlets between the inlet adjacent the lower end of the housing and the outlets. 
     
     
         3 . The centrifugal separator as claimed in  claim 1 , wherein the plurality of outlets adjacent the upper end of the housing have variable positions. 
     
     
         4 . The centrifugal separator as claimed in  claim 1 , wherein the upper end of the rotatable tank is divided into four to eight chambers. 
     
     
         5 . The centrifugal separator as claimed in  claim 1 , wherein the upper end of the rotatable tank is divided into four chambers.
