A method of remediating and recovering energy from
combustion products from a
fossil fuel power
plant having at least one
fossil fuel combustion chamber, at least one compressor, at least one
turbine, at least one
heat exchanger and a source of
oxygen.
Combustion products including non-condensable gases such as
oxygen and
nitrogen and condensable vapors such as
water vapor and acid gases such as SOX and
NOX and CO2 and pollutants are produced and energy is recovered during the remediation which recycles
combustion products and adds
oxygen to support combustion. The temperature and / or pressure of the
combustion products are changed by cooling through heat exchange with thermodynamic working fluids in the power generation cycle and / or compressing and / or heating and / or expanding the
combustion products to a temperature / pressure combination below the
dew point of at least some of the condensable vapors to condense liquid having some acid gases dissolved and / or entrained and / or directly condense
acid gas vapors from the
combustion products and to entrain and / or dissolve some of the pollutants while recovering sensible and / or
latent heat from the combustion products through heat exchange between the combustion products and thermodynamic working fluids and / or cooling fluids used in the power generating cycle. Then the CO2, SO2, and H2O poor and oxygen enriched remediation
stream is sent to an exhaust and / or an
air separation unit and / or a
turbine.
