  • Patent number: 6209307
    Abstract: The present invention is directed to a process for generating work that comprises the steps of: (a) combusting natural gas and oxygen in a combustor to form a gas stream; (b) passing the gas stream through a regenerator where heat from the gas stream causes a strong liquor present in the regenerator to form a carbon dioxide stream and a weak liquor, the reduction of heat from the gas stream resulting in an exhaust gas stream; (c) extracting work from the carbon dioxide stream resulting in a work-extracted carbon dioxide stream; (d) introducing the work-extracted carbon dioxide stream, the exhaust gas stream and the weak liquor to an absorber to cause carbon dioxide to be absorbed by the weak liquor converting the weak liquor into the strong liquor; (e) introducing said carbon dioxide stream remaining from the absorber to waste and/or the combustor; and (f) introducing the strong liquor from the absorber to the regenerator.
