  • Patent number: 11679367
    Abstract: A reactor system for thermally treating a hydrocarbon-containing stream, that includes a pressure containment vessel comprising an interior chamber and a heat transfer medium that converts electrical current to heat and is positioned within the interior chamber of the pressure containment vessel, wherein the heat transfer medium comprises a first end face, a second end face, and channels extending between the first end face and the second end face. A process for thermally treating a hydrocarbon-containing stream includes introducing the hydrocarbon-containing stream into the reactor system, pressurizing the pressure containment vessel and the heat transfer medium without heating the pressure containment vessel or the heat transfer medium, supplying electrical current to the heat transfer medium, converting the electrical current to heat, heating the hydrocarbon-containing stream, and converting the hydrocarbon-containing stream to an effluent stream.

  • Patent number: 11666882
    Abstract: Flow control mechanisms control the direction and flow rate of synthesis reagent through one or more synthesis reaction vessels for automated solid phase synthesis. Selectable, known, and reproducible positive or negative pressure differentials (?5 to +10 psi) accomplish controlled, bidirectional (forward and reverse) flow of synthesis reagents through synthesis media contained within the reaction vessels. Venturi-based vacuum apparatus, valves, electronic pressure regulators and compound digital pressure gauge, can be added to automated solid phase synthesis instruments to provide, control, and monitor known, selectable, reproducible negative and positive pressures to one or both valve sealable and un-sealable ends (inlets and outlets) of the reaction vessel as needed to generate and reverse said pressure differentials between the opposite ends of said synthesis reaction vessels, yielding controlled forward and backward flows of synthesis reagents through the synthesis media.
