  • Patent number: 11117104
    Abstract: The present invention relates to a composite membrane for gas separation and/or nanofiltration of a feed stream solution comprising a solvent and dissolved solutes and showing preferential rejection of the solutes. The composite membrane comprises a separating layer with intrinsic microporosity. The separating layer is suitably formed by interfacial polymerisation on a support membrane. Suitably, at least one of the monomers used in the interfacial polymerisation reaction should possess concavity, resulting in a network polymer with interconnected nanopores and a membrane with enhanced permeability. The support membrane may be optionally impregnated with a conditioning agent and may be optionally stable in organic solvents, particularly in polar aprotic solvents. The top layer of the composite membrane is optionally capped with functional groups to change the surface chemistry. The composite membrane may be cured in the oven to enhance rejection.

  • Patent number: 9670072
    Abstract: A computer-implemented method for determining a water treatment parameter includes receiving, by a computer, measurements of a fluorescence emission spectrum of a water sample including a first peak emission wavelength and at least a second peak emission wavelength, emitted in response to an excitation wavelength, receiving, by the computer, an absorbance measurement obtained at the excitation wavelength of the water sample, determining, using the computer, a ratio of the measurements at either the second peak emission wavelength, or a sum of measurements at a plurality of peak emission wavelengths including at least the first peak emission wavelength and the second peak emission wavelength, to the first peak emission wavelength, and calculating, using the computer, a value for the water treatment parameter based on a combination of at least the ratio and the absorbance measurement.

  • Patent number: 9517981
    Abstract: Gas separation processes are provided for separating dehydrogenation reaction products from a raw gas stream to recover hydrocarbons, specifically olefins, such as propylene and iso-butene, as well as unreacted feedstock. The processes employ a sequence of partial condensation steps, interspersed with membrane separation steps to raise the hydrocarbon dewpoint of the uncondensed gas, thereby avoiding the use of low-temperature or cryogenic conditions.

  • Patent number: 9255864
    Abstract: A first apparatus (100) for processing a liquid sample is disclosed. The apparatus (100) includes a sample-receiving (120), a filtrate-receiving component (150), and an analyte-capture element (170). The apparatus (100) forms a liquid flow path through which the sample passes, thereby causing the analyte-capture element (170) to capture an analyte, if present. A method is disclosed whereby a liquid sample is passed through the first (100) apparatus and the analyte-capture element (170) is easily separated from the apparatus for further processing and detection of the analyte. A structurally-related second apparatus (200) for processing a plurality of liquid samples, and a corresponding method of use, also is disclosed.

  • Patent number: 9219292
    Abstract: The nonaqueous electrolyte secondary battery 100 according to the present invention is provided with a wound electrode assembly in which a positive electrode sheet and a negative electrode sheet are wound, with a porous separator sheet 30 interposed therebetween. A filler layer 40 comprising an inorganic filler and a binder is formed on one side of the separator sheet 30. The filler layer 40 is continuously provided from the winding start end 38A to the winding finish end 38B of the separator sheet 30 in the winding direction of this sheet. The separator sheet 30 has low porosity regions 36A, 36B, which have a lower porosity than a location 35 outside these regions, in regions having prescribed width WA, WB from the winding start end 38A and/or the winding finish end 38B of the sheet toward the center of the sheet.

  • Patent number: 9149790
    Abstract: The present invention provides a porous material which has continuous pores and comprises a polymethyl methacrylate as a main component, wherein the continuous pores have a diameter of 0.001 ?m to 500 ?m and at least one surface of the porous material has a porosity of 10% to 80%; a separation membrane composed of the same; an adsorbent composed of the same; and a method production of the same. A porous material whose surface porosity and pore diameter are each controlled in a specific range can be obtained. The porous material has a fine and uniform porous structure in which the pore diameter can be controlled in the order of nanometers to micrometers; therefore, it can be advantageously used as a separation membrane such as a blood component separation membrane of an artificial kidney or the like or as an adsorbent.

  • Patent number: 9114366
    Abstract: Tangential flow filtration device is provided wherein liners are provided between the filtration element and the top and bottom holders or manifolds. The liners incorporate the flow channels and inlet and outlet ports that were previously present in the manifolds. The liners are made of an inexpensive material and therefore are disposable after a single use, making it more cost effective to dispose of them than to clean the conventional manifolds. In addition, the liners can be pre-sterilized.
