    Abstract: The present invention relates to the separation of liquid two-phase dispersions into phases and may be used in the chemical, food, and microbiological industries. An emulsion is first transformed into an aerosol with a gas as the dispersion medium and particles of the dispersion medium and dispersed phase of the initial emulsion as the dispersed phase. The resulting aerosol is then subjected to centrifugal forces, and the emulsion constituent phases are drained separately. The method may be used to break the first type emulsions or the second type emulsions. Emulsion may be aerosolized by hydraulic, or pneumatic, or ultrasonic atomizing in a gas medium. Air, or an inert gas, or nitrogen, may be used as the gas medium. The invention improves emulsion phase separation efficiency while reducing associated energy consumption.

    Abstract: Embodiments of the present invention relate to an underwater gas/liquid-liquid modular separation system which enables the disposal of produced water in undersea environment. The underwater gas/liquid-liquid modular system separation consists of a gravitational separator and a water polishing system consisting of deoiling membranes capable of withdrawing the residual oil contained in water. Furthermore, the underwater gas/liquid-liquid modular separation system also features a demulsifier injection which promotes the breakdown of the water-oil emulsion. Embodiments further relate to an underwater gas/liquid-liquid separation method and to the use of deoiling membranes in gas/liquid-underwater liquid separation systems.

    Abstract: A demulsification process for extracting surface active biochemical products from crude oil and its fractions when they are used as feedstock during biochemical productions utilizes subcritical/supercritical C0 2 as a proton pump. The process also includes a pH tuning step, thereby inducing demulsification and precipitation of biochemical products into the aqueous phase, but avoiding asphaltene precipitation by apriori addition of resinous solvents derived from crude oil or bioresources. The biochemical products are then extracted from the aqueous phase via temperature change or some other technique.
