    Abstract: A process can be used for preparing nano- or microparticles containing a carrier-polymer and a biologically active ingredient. The process is a solvent emulsion process involving an organic phase (OP) and an aqueous phase (AP) to form an emulsion. In the case of an oil-in-water emulsion (O/W), the organic phase (OP) contains the biologically active ingredient dissolved or dispersed therein. Alternatively, in the case of a water-in-oil emulsion (W1/O), the aqueous phase (AP) contains the biologically active ingredient dissolved or dispersed therein. The organic phase (OP) is saturated with the salt-containing aqueous phase (AP) and vice versa.

  • Patent number: 8349771
    Abstract: Using a complex emulsion for treating a subterranean formation, such as to dissolve minerals therein (e.g. carbonates, scales, and/or filter cake) to improve permeability, substantially improves post treatment fluid clean-up for improved hydrocarbon production. The complex emulsion is made by mixing an acid aqueous phase with an oil external microemulsion to give an initial product, where the acid aqueous phase is an external phase and the microemulsion is an internal phase. Then the initial product is mixed with a second oil (e.g. xylene, diesel, toluene, kerosene, other aromatics, refined hydrocarbons and the like) containing an emulsifier to make a complex emulsion.

  • 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.
