    Abstract: Improvements to filtration and vessels such as for filtration and coalescing of gas streams are shown. A filter element with a partial treated region and untreated region such as providing different surface energies or other filtration characteristics are provided. Various keying arrangements for compatibility and/or rotational locking are shown between the filtration vessel, a tubular coalescing baffle, and/or filter element. The tubular coalescing baffle also may include non-louvered pore structure, which provides for more even flow in a two stage type filtration vessel to prevent premature exiting and reduction of flow velocities along the second stage, and/or may additionally or alternatively include drainage apertures such as drain slot formed along a gravitational bottom or otherwise to facilitate additional drainage of coalesced liquid as opposed to letting such liquid be forced through fluid velocity toward the open end of the tubular baffle.

  • Publication number: 20140336295
    Abstract: A porous body consists essentially of a plurality of ceramic particles having an average size ranging from 8 to 100 nm. The ceramic particles are bonded to adjacent ceramic particles with a strength sufficient to render the porous body self-supporting. The porosity ranges from 30 to 70 vol. % and the average pore size ranges from 5 to 50 nm. The porous body may be manufactured by preparing a dispersion comprising the ceramic particles and a polymer matrix material in a solvent, removing the solvent by heating and/or evaporation, forming a preform of the dried material, and firing the preform to remove the polymer matrix material and bond the ceramic particles to each other. The porous body is useful as a filter element in a system adapted to remove nanoscale particles from a fluid stream.
