  • Separation process for a liquid phase dispersed in a continuous liquid phase
    Patent number: 4900452
    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.
