  • Patent number: 10967336
    Abstract: The disclosed invention is device for preparation of an emulsion and a method for producing an emulsion. The method comprises the steps of: (1) causing water and a water-insoluble substance that is to be emulsified to become freely miscible under conditions of temperature and pressure in the vicinity of the vapor-liquid critical point of water; and (2) cooling the product comprised of the water-insoluble substance and water solved each other in the presence of a surfactant to obtain a liquid comprised of the water-insoluble substance dispersed in water or a liquid comprised of water dispersed in the water-insoluble substance. The present invention provides a new device and a new method for producing emulsions with high efficiency without requiring a long period of processing or a great amount of energy.

  • Patent number: 10610838
    Abstract: The present invention relates to a method and device for emulsifying emulsion explosive: an oil phase and a part of a water phase having undergone split-flow enter a first stage coarse emulsion mixer; after mixing, the mixture together with a part of the water phase having undergone second stage split-flow enters a second stage coarse emulsion mixer; the obtained mixture together with a part of the water phase having undergone third stage split-flow enters a third stage coarse emulsion mixer for mixing; forming a coarse emulsion matrix after multiple stages of mixing, and finally completing emulsification after mixing in a multi-stage fine emulsion mixer. The method and device mix the water phase with the oil phase multiple times according to a desired ratio, thus greatly reducing the stored explosive, with no mechanical stirring or shearing, with no heat accumulation, and with low pressure, without requiring matrix pumping, thus enhancing safety.

  • Patent number: 8314157
    Abstract: Improved method, apparatus and system for treating bilge water and other marine emulsion wastes comprising water and hydrocarbon, and possibly solids in some cases. Microwave Separation Technology (MST) is used to treat a broad class of emulsion wastes associated with, generated by, or carried at sea on, ships or other marine entities (such as drilling platforms, oil spill clean-up systems, etc.). The hydrocarbon component from a marine emulsion waste comprising water and hydrocarbon, and possibly solids in some cases, is concentrated (e.g., the emulsion's water content is reduced) so that the volume of waste material that requires off-loading or out-hauling (or both) is reduced over conventional methods of separating emulsion wastes for disposal. In view of the reductions achieved in process volumes, significant cost savings may be realized. Better compliance with environmental laws and standards may also be realized.

  • Patent number: 8211973
    Abstract: In a process for the production of a silicone in water emulsion in which a polysiloxane fluid, at least one surfactant and water are continuously fed to a high shear mixer in such proportions as to form a viscous oil in water emulsion which is continuously withdrawn from the mixer. The polysiloxane fluid may be a non-reactive fluid or may have reactive groups capable of taking part in a chain extension reaction. A desired emulsion particle size can be maintained by monitoring the pressure in the supply line at the inlet to the high shear mixer.
