Patent ID: 8087926

Claim:
An oxygen fueled integrated pollutant removal and combustion system comprising: an oxy-fuel combustion system for producing a flue gas containing CO 2 and other gases and substantially void of non-fuel borne nitrogen containing combustion produced gaseous compounds; and a pollutant removal system for directly receiving flue gas from said oxy-fuel combustion system and consolidating removal of multiple pollutants from said flue gas in a single process, said pollutant removal system comprising: at least one direct contact heat exchanger for bringing said flue gas into intimated contact with a cooling liquid to produce a pollutant-laden liquid stream which includes soluble and entrained particulates and a stripped flue gas stream containing condensable and non-condensable vapors; a discharge for discharging said pollution laden stream; one or more compressors for receiving said stripped flue gas stream from said at least one direct contact heat exchanger and compressing said stripped flue gas stream defining a compressed flue gas stream; at least one heat exchanger for receiving the compressed flue gas stream from said at least one or more compressors, said one or more compressors and said at least one heat exchanger configured to separate condensable vapors from non-condensable vapors by way of cooling of said compressed flue gas stream in order to condense said CO 2 and any other condensable vapors defining condensed vapors and non-condensable vapors; a discharge connected to said at least one heat exchanger for discharging said condensed vapors; and a filter connected to said at least one heat exchanger for filtering said non-condensable vapors before releasing the flue gas to the atmosphere.
