  • Patent number: 11519537
    Abstract: A sealing assembly for flanges is described. The sealing assembly includes a wedge, a first sealing element, a second sealing element, and a fastener. The wedge has a first surface, a second surface, and a third surface. The first surface defines a pressure void with a first flange and a second flange. The first sealing element engages the second surface of the wedge and the first flange. The second sealing element engages the third surface of the wedge and the second flange. The fastener couples the first sealing element, the first flange, the second flange, and the second sealing element together. The wedge slides toward the sealing elements responsive to a pressure increase in the pressure void. The sealing elements force the flanges toward each other responsive to the wedge sliding toward the first sealing element and the second sealing element.

  • Patent number: 11517859
    Abstract: Composite materials for removing hydrophobic components from a fluid include a porous matrix polymer, carbon nanotubes grafted to surfaces of the porous matrix polymer, and polystyrene chains grafted to the carbon nanotubes. Examples of porous matrix polymer include polyurethanes, polyethylenes, and polypropylenes. Membranes of the composite material may be enclosed within a fluid-permeable pouch to form a fluid treatment apparatus, such that by contacting the apparatus with a fluid mixture containing water and a hydrophobic component, the hydrophobic component absorbs selectively into the membrane. The apparatus may be removed from the fluid mixture and reused after the hydrophobic component is expelled from the membrane. The composite material may be prepared by grafting functionalized carbon nanotubes to a porous matrix polymer to form a polymer-nanotube composite, then polymerizing styrene onto the carbon nanotubes of the polymer-nanotube composite.

  • Patent number: 11518941
    Abstract: An open system pyrolysis of a first hydrocarbon source rock sample obtained from a natural system is performed within a pyrolysis chamber by maintaining the pyrolysis chamber at a substantially constant temperature. Hydrocarbons are recovered from the pyrolysis chamber released by the first hydrocarbon source rock sample. A thermo-vaporization is performed within the pyrolysis chamber on the pyrolyzed sample at a substantially constant temperature. A first hydrocarbon expulsion efficiency of hydrocarbon source rock is determined. A second hydrocarbon rock sample is ground to a grain size less than or equal to or less than 250 micrometers. A second pyrolysis is performed on the ground hydrocarbon source rock sample by maintaining the chamber at a substantially constant temperature. A second hydrocarbon expulsion efficiency of the hydrocarbon source rock in the natural system is determined. The first hydrocarbon expulsion efficiency is verified using the second hydrocarbon expulsion efficiency.
