  • Method and apparatus for fueling vehicles with liquefied cryogenic fuel
    Patent number: 5771946
    Abstract: Apparatus for, and a method of, withdrawing liquefied cryogenic fuel stored in a primary insulated storage tank at a relatively low pressure and temperature; increasing the pressure of the withdrawn liquefied cryogenic fuel through a heat exchanger to warm the liquefied cryogenic fuel to a subcooled or near saturated liquid condition; and feeding the warmed and pressurized liquefied cryogenic fuel to an insulated tank on a vehicle at a refueling facility, said vehicle using liquefied cryogenic fuel as its fuel and the insulated vehicle fuel tank being adapted to safely contain and store the liquefied cryogenic fuel in liquid form, at an approximate saturated condition.
    Type: Grant
    Filed: June 17, 1996
    Date of Patent: June 30, 1998
    Assignee: Chicago Bridge & Iron Technical Services Company
    Inventors: Richard John Kooy, Mervyn Ladd Conrad, David John Forgash, Raymond Korzonas, Bryan Patrick Neuhalfen, George D. Rhoades, Jack Wayne Sudduth
  • Method and apparatus for fueling vehicles with liquefied cryogenic fuel
    Patent number: 5687776
    Abstract: Apparatus for, and a method of, withdrawing liquefied cryogenic fuel stored in a primary insulated storage tank at a low pressure and at a temperature close to its boiling point; increasing the pressure of the withdrawn liquefied cryogenic fuel and then feeding the pressurized liquefied cryogenic fuel through a heat exchanger to warm the liquefied cryogenic fuel to a subcooled or near saturated liquid condition; and feeding the said warmed and pressurized liquefied cryogenic fuel to an insulated tank on a vehicle at a refueling facility, the vehicle using liquefied cryogenic fuel as its fuel and the insulated vehicle fuel tank being adapted to safely contain and store the said liquefied cryogenic fuel in liquid form, at an approximate saturated condition.
