Including Emulsion Breaking Patents (Class 210/708)
  • Patent number: 10343130
    Abstract: A method processes a stable emulsion having components from whole-cell biotransformations such as cells, soluble cell components, organic solvents and/or water. In this connection, the emulsion, which is stable after the biotransformation, is mixed with further parts of organic phase, and subsequently the mixture is continuously stirred until a catastrophic phase inversion of the emulsion takes place while mixing; subsequently, this phase-inverted mixture is transferred to a settling container, where the phases of the emulsion separate from one another and can be separated from one another.

A model is used that relates height dependent properties of liquid in the vessel to properties of the detected ultrasound transmission between transceivers, the model comprising at least a fittable parameter of a height dependent droplet size distribution in a least a sub-range of a height of liquid in the vessel. The model relating the droplet size distribution to ultrasound wavelength dependence of the properties of ultrasound transmission.

  • Publication number: 20130334142
    Abstract: Oil-containing water is separated in a separator in an automated/continuous operation using devices that is free of moving parts in the separation container. Operation is preferably entirely controlled via adjustment of various flow rates, typically using flow control valves and/or feed pumps in response to measurement of a guided wave radar device or other IDLT.

  • Patent number: 8596346
    Abstract: A method of flocculating coal fines from produced water that includes the steps of: (A) mixing at least: (i) produced water, wherein the produced water comprises suspended coal fines; (ii) one or more oil-soluble phosphate esters; and (iii) water-immiscible solvent; wherein the mixing is in proportions to obtain an oil-in-water emulsion; (B) allowing or mechanically causing the oil-in-water emulsion to substantially break into: (i) a first fluid having a continuous phase comprising at least some of the water from the produced water; and (ii) a second fluid having a continuous phase comprising at least some of the water-immiscible solvent; and (C) mechanically separating the first fluid and the second fluid. Optionally, the step of mixing further includes mixing with a crosslinker for the one or more phosphate esters to form a gel for suspending the separated coal fines.

  • Publication number: 20130292341
    Abstract: The present invention provides a method and system for separating phases of a liquid mixture or dispersion from each other. The system includes a settler system, which includes a coalescing-enhancing plate comprising a front face and rear face and a plurality of openings. The openings are configured to selectively manipulate the flux of portions of the mixture to thereby increase phase separation of the mixture.

  • Publication number: 20130292339
    Abstract: An oil/water emulsion is mixed with functional solid particles to agglomerate oil droplets and/or water droplets having functional solid particles and the functional solid particles are hydrophobicized for the agglomeration of oil droplets or are hydrophilicized for the agglomeration of water droplets. This enables oil and water to be separated from an oil/water emulsion under gravitational forces.

  • Publication number: 20130284677
    Abstract: Method and system for extracting and recovering hydrocarbons from wastewater and treating the water to improve its condition. A series of specific unit operations result in the extraction of hydrocarbons, solids and contaminants and the treatment of water to a condition which is fit for re-use or environmentally sustainable discharge. Phase separation between the water and hydrocarbons is effected using flotation techniques followed by collection of the hydrocarbons using a movable collection surface. The aqueous phase is processed by multiple filtration steps. The result is significant extraction and recovery of hydrocarbons and conservation of water for re-use or discharge to the environment in a process which is continuous and scalable for large or small operations.

  • Publication number: 20130273124
    Abstract: Fibrillar bacterial proteins can be mixed with oil in or on water. The interaction of the proteins at the oil-water interface can result in oil dispersion in water in the form of droplets surrounded by an aggregated protein film The film may be formed by multiple layers of the fibrillar proteins with water between adjacent protein layers. The proteins may be derived from bacterial cells, such as Bacillus subtilis. The encapsulated oil droplets can be collected from the water, for example, as part of an oil spill clean-up or oil storage. The oil may be removed from the collected droplets, for example, by evaporation to produce a three-dimensional network composed of the aggregated films. The three-dimensional network material can be used as a coating for transplant material, grafted onto implant material to improve biocompatibility, as a precursor for tissue growth or engineering, or provided into a human or animal body.

  • Publication number: 20130270192
    Abstract: An immiscible lipophilic or hydrophilic liquid phase is separated respectively from a continuous hydrophilic or a lipophilic phase liquid. Fibers having hydrophilic and hydrophobic properties are formed into a filter. The separation mechanism involves coalescence of the small droplets into larger droplets as the immiscible liquid flows through the fiber filter, and release of the large immiscible droplets from the filter. With respect to separation of a hydrophilic immiscible fluid in a lipophilic continuous fluid, the hydrophobic fibers cause small water droplets to migrate towards the hydrophilic fibers whereby large droplets are formed on hydrophilic surface. The large droplets coalescence until they are so large that they are released and drained off of the filter. The filter media can be designed by mixing hydrophilic and hydrophobic fibers in various proportions to achieve an optimum wettability range for separation of the immiscible liquid from the continuous phase liquid.
