  • Process and apparatus for the production of synthesis gas
    Patent number: 6669744
    Abstract: A process for the production of synthesis gas from a hydrocarbon fuel and steam and/or oxygen gas wherein at least part of any steam requirement is provided by heat exchange against exhaust gas from a gas turbine driving an air separation unit supplying at least part of any oxygen requirement for the synthesis gas production. The process is particularly applicable when the synthesis gas is used to prepare a synfuel by methanol synthesis or a Fischer-Tropsch process.
    Type: Grant
    Filed: November 22, 2002
    Date of Patent: December 30, 2003
    Assignee: Air Products and Chemicals, Inc.
    Inventors: Rodney John Allam, Rebecca Cotton
  • Process and apparatus for the generation of power
    Patent number: 6615589
    Abstract: A process for generating power from the expansion of steam in a steam turbine system. The steam is generated by at least partially vaporizing pre-heated water by heat exchange against a first fuel gas that is generated exothermically. The at least partially vaporized water is then heated to produce the steam by heat exchange against expanded combustion product gas that is generated by the combustion of a second fuel gas in the presence of compressed oxygen-containing gas and the subsequent expansion of the combustion product gas. The steam is then expanded in a steam turbine system having more than one pressure stage to produce power and an expanded steam stream.
