Abstract

Apparatus comprises a vessel, means for passing the emulsion in an upward direction through the vessel and means for draining the vessel, a coalescer (1) located in the vessel, the coalescer having a first face and a second face, means (4,8) for moving the coalescer from a first position in which its first face is on the underside of the coalescer to a second position in which the second face is on the underside of the coalescer and vice versa, outlet means for the treated emulsion and means for removing coalesced oil droplets from the treated emulsion. In use, upward passage of emulsion through the coalescer is periodically interrupted for draining of the vessel to cause 6 temporary reversal of flow through the coalescer for solids removal therefrom and for movement of the coalescer so that its first and second faces are alternately on the underside. <IMAGE>
