  • Internal exchanger for gas-liquid-solid reactor for fischer-tropsch synthesis
    Patent number: 7776287
    Abstract: This present invention describes a novel type of internal exchanger intended to carry out Fischer-Tropsch synthesis. This exchanger has a modular design and comprises a central tube with partitions allowing at the same time the supply of coolant to the hairpins of the module and the recovery of the partially vaporized fluid from these same hairpins.
    Type: Grant
    Filed: April 20, 2007
    Date of Patent: August 17, 2010
    Assignees: Institut Francais du Petrole, ENI S.p.A.
    Inventors: Francois Hugues, Bertrand Szymkowiak, Jean-Christophe Viguie, Jean-Marc Schweitzer, Michel Munier, Dominique Chretien, Eric Caprani, Damien Douziech
  • Internal exchanger for gas-liquid-solid fluidized bed reactor employing a highly exothermic reaction
    Patent number: 7758824
    Abstract: The present invention describes a novel type of internal exchanger for a gas-liquid-solid fluidized bed reactor employing a strongly thermal reaction. Said exchanger is modular in concept and comprises a central tube with separations allowing both supply of cooling fluid to the pins of the module and collection of partially vaporized fluid from said same pins.
