  • Hybrid pumper
    Patent number: 8943842
    Abstract: A process and apparatus that includes a cryogenic source for providing a cryogenic fluid for vaporization, a cryogenic pump in fluid flow communication with the cryogenic source for increasing the pressure of the cryogenic fluid, an unfired vaporizer coolant circuit 110 in fluid flow communication with the cryogenic pump and adapted to accept the cryogenic fluid to form a heated stream, a direct-fired vaporizer downstream and in fluid flow communication with the unfired vaporizer coolant circuit 110 and adapted to accept the heated stream from the unfired vaporizer coolant circuit to form a superheated stream; and a diesel engine power unit 118 to provide power to the cryogenic pump, the unfired vaporizer coolant circuit 110, and the direct-fired vaporizer.
    Type: Grant

    Date of Patent: February 3, 2015
    Assignee: Air Products and Chemicals, Inc.
    Inventors: John Charles Street, Paul Martin Davis
  • Cryogenic reciprocating pump intermediate distance piece
    Patent number: 8915719
    Abstract: The present invention teaches providing heating elements into the nose of an intermediate distance piece of a cryogenic reciprocating pump in order to warm the piston packing seals of the pump. The heating elements increase the temperature of the piston packing seals to limit deformation of the seals while the pump is in operation. In addition, a warm, dry vapor purge may be provided to the interior of the intermediate distance piece to reduce or eliminate rime from interfering with the piston packing seals.
