ABSTRACT:
A system for treating organic emulsions by separating by coalescence the disperse phase from the dispersion phase of the emulsion includes a single enclosed chamber having therein a lower destabilizing area, a central filtering and coalescence area, and an upper flotation and separation area. An emulsion to be treated is continuously introduced and passed upwardly through the destabilizing area, the filtering and coalescence area and the flotation and separation area. The flotation and separation area includes a center portion positioned vertically above the filtering and coalescence area and at least one lateral portion in flow communication with the center portion and extending laterally downwardly along a side of the filtering and coalescence area and the destabilizing area. The lateral portion of the flotation and separation area is laterally separated from the filtering and coalescence area and from the destabilizing area by a partition. The disperse phase of the emulsion is withdrawn by a first withdrawal means from upper portions of the center and lateral portions of the flotation and separation area. The dispersion phase is withdrawn by second withdrawal means separate from the first withdrawal means from the lower part of the lateral portion of the flotation and separation area.
