  • Patent number: 10427110
    Abstract: This invention discloses a membrane composition, a method of making, and applications for a new type of high selectivity, high plasticization-resistant and solvent-resistant, both chemically and UV cross-linked polyimide membranes. Gas permeation tests on these membranes demonstrated that they not only showed high selectivities, but also showed extremely high CO2 plasticization resistance under CO2 pressure up to 4923 kPa (700 psig). This new type of high selectivity, high plasticization-resistant and solvent-resistant, both chemically and UV cross-linked polyimide membranes can be used for a wide range of gas separations such as separations of H2/CH4, He/CH4, CO2/CH4, CO2/N2, olefin/paraffin separations (e.g. propylene/propane separation), O2/N2, iso/normal paraffins, polar molecules such as H2O, H2S, and NH3 mixtures with CH4, N2, H2, and other light gases separations. The membranes can also be used for liquid separations such as in the removal of organic compounds from water.

  • Patent number: 10399024
    Abstract: Surface modified filter media, including surface modified filter media having enhanced performance characteristics, are provided. In some embodiments, a filter media may comprise two or more layers designed to enhance fluid separation efficiency. One or more of the layers may have at least a portion of a surface that is modified to alter and/or enhance the wettability of the surface with respect to a particular fluid. In certain embodiments involving a filter media including more than one surface modified layer, at least one surface modified layer may have a greater air permeability and/or mean flow pore size than that of another surface modified layer. Such a configuration of layers may result in the media having enhanced fluid separation properties compared to filter media that do not include such modified layers or configuration of layers, all other factors being equal. The filter media may be well-suited for a variety of applications, including filtering fuel, air, and lube oil.
