  • Preparation of stable emulsion using dynamic or static mixers
    Patent number: 6677387
    Abstract: A process for preparing a hydrocarbon in water emulsion, comprising the steps of providing a liquid additive that tends to gel when mixed with water at temperatures less than a gelling temperature TG; providing a stream of water at a temperature TC less than the gelling temperature TG; feeding said stream to a mixer having a mixer inlet so as to impart energy to the stream; adding the liquid additive to the stream downstream of the mixer inlet, whereby the liquid additive mixes with the stream and the energy inhibits gelling of the liquid additive so as to provide a substantially homogeneous solution of the liquid additive in the water; and mixing the solution with a hydrocarbon in a mixer so as to form a hydrocarbon-in-water emulsion. In further accordance with the invention, different emulsions can be formed and combined so as to provide a combined emulsion having desired properties.

  • System and method for the recovery of oil in water emulsion spilled in water
    Patent number: 5935447
    Abstract: A method for on line recovery of oil from an oil in water emulsion spilled in water includes the steps of: obtaining a stream of recovered material including an oil in water emulsion and water; inducing a gas into the stream and applying shear so as to provide a mixture wherein oil from the oil in water emulsion is adhered to bubbles of the gas; passing the mixture to a flotation compartment for allowing the oil adhered to the bubbles to rise to a surface of the mixture; and removing the oil from the surface of the mixture.
