Abstract: The present invention relates to a separator for two liquids which are not miscible, consisting of a cylindrical casing (1) in which there are active capacities (9, 10) and passive capacities (8, 35), the passive capacities (8, 35) being disposed at each of the ends of the direction of circulation (FF) of the liquid in the cylinder and serving either as a tranquilizing zone or as a decantation zone or as a buffer zone, at least two active capacities (9, 10) being connected by a common skimmer disposed in the center of the cylindrical casing (1), the active capacities (9, 10) being disposed between the passive capacities (8, 35) and being provided with a rotor-stator assembly (13, 14) adapted to carry out separation by induced air.

Abstract: A process and apparatus for separating a liquid phase dispersed in a heavier continuous liquid phase, such as a hydrocarbon dispersion in an aqueous phase, of the floatation type, wherein gas bubbles are generated in the continuous phase to assure ascending entrainment of the dispersed phase, the gas bubbles being formed from a mixture of at least one base gas which is only slightly soluble in the continuous phase, and at least one transfer gas with a higher solubility in the continuous phase, such as instance ammonia, thereby significantly improving the separation yield and efficiency.

Abstract: Process and device for breaking stabilized emulsions.Such a device is constituted by a tank divided into two compartments by a permeable membrane constituting a percolating electrode connected to a continuous or pseudo-continuous electric current supply, a first compartment provided with emulsion feed means and a second compartment provided with means for evacuating the effluent.This device is particularly adapted to the treatment of oil-water emulsions.
