INTEGRATED CAPTURE OF FOSSIL FUEL GAS POLLUTANTS INCLUDING CO2 WITH ENERGY RECOVERY

摘要

A method of reducing pollutants exhausted into the atmosphere from the combustion of fossil fuels. The disclosed process removes nitrogen from air for combustion, separates the solid combustion products from the gases and vapors and can capture the entire vapor/gas stream for sequestration leaving near-zero emissions. The invention produces up to three captured material streams. The first stream is contaminant-laden water containing SO_x, residual NO_x particulates and particulate-bound Hg and other trace contaminants. The second stream can be a low-volume flue gas stream containing N₂ and O₂ if C0₂ purification is needed. The final product stream is a mixture comprising predominantly CO₂ with smaller amounts Of H₂O, Ar, N₂, O₂, SO_?, N0_?. Hg, and other trace gases.
