Abstract
A method and apparatus for the separation of an emulsion of at least one dispersed phase emulsified in at least one continuous phase of different density wherein the emulsion is passed into a vessel and axially through a fixed coalescing bed for coalescing the dispersed phase, and continuing the flow over a guide wettable by the dispersed phase whereby the coalesced dispersed phase travels along the guide axially to establish a layer of the coalesced dispersed phase and the continuous phase passes substantially radially outwardly through the guide to establish a layer of the continuous phase, the interface of the dispersed phase and the continuous phase being maintained at approximately the midpoint of the guide.
