  • Patent number: 8529667
    Abstract: A process for the extraction of an unwanted material from a gas or liquid comprising the steps of introducing an extraction liquid into the fluid having an unwanted liquid therein to form a physical microdispersion comprising a plurality of extraction liquid droplets and the fluid, allowing the plurality of extraction liquid droplets to interact with the unwanted component in the fluid, to cause the extraction liquid droplets to be “wetted out” and captured on a porous medium, where the liquid is further contacted by the gas and simultaneously formed into a plurality of coalesceable droplets, coalescing the coalesceable droplets into larger droplets containing the unwanted liquid, and separating the larger droplets containing the unwanted liquid from the fluid.
    Type: Grant

  • Patent number: 8425663
    Abstract: A process for the extraction of an unwanted material from a gas comprising the steps of introducing an extraction liquid into a fluid having an unwanted liquid therein to form a physical aerosol comprising a plurality of extraction liquid droplets and the fluid, allowing the plurality of extraction liquid droplets to interact with the unwanted liquid in the gas to cause the extraction liquid droplets to be “wetted out” and captured on a porous medium, where the liquid is further contacted by the gas and simultaneously formed into a plurality of coalesceable droplets, coalescing the coalesceable droplets into larger droplets containing the unwanted liquid, and separating the larger droplets containing the unwanted liquid from the fluid.

  • Publication number: 20100243554
    Abstract: Some embodiments of the disclosure are directed to a fluid filter assembly including an outer filter element having a hollow core and an inner filter element having a hollow core. The inner filter element can be positioned within the hollow core of the outer filter element, thereby defining an internal fluid passage. In some embodiments, the first end of the outer filter element and the first end of the inner filter element can be supported by an open endcap assembly, which can also include a fluid inlet in fluid communication with the internal fluid passage. In some embodiments, at least one of the filter elements can include a pleated filter media.
