  • Electrical power generation apparatus
    Patent number: 8196387
    Abstract: An apparatus for generating electrical power in which a synthesis gas stream generated in a gasifier is partially oxidized, expanded and thereafter, is combusted in an oxygen transport membrane system of a boiler. The combustion generates heat to raise steam to in turn generate electricity by a generator coupled to a steam turbine. The resultant flue gas can be purified to produce a carbon dioxide product.
    Type: Grant

    Date of Patent: June 12, 2012
    Assignee: Praxair Technology, Inc.
    Inventors: Minish Mahendra Shah, Aqil Jamal, Raymond Francis Dmevich, Bart Antonie van Hassel, Gervase Maxwell Christie, Hisashi Kobayashi, Lawrence E. Bool, III
