Abstract:
1. An oxygen fueled integrated pollutant removal and combustion system comprising: a combustion system having at least one burner, and configured to substantially prevent the introduction of air, an oxygen supply for supplying oxygen at a predetermine purity greater than 21 percent, a carbon based fuel supply for supplying a carbon based fuel, a control system for feeding the oxygen and the carbon based fuel into the at least one burner in controlled proportion to each other and controlling the combustion of the carbon based fuel to produce a flame temperature in excess of 3000 degrees F. and a flue gas stream containing CO a pollutant removal system for processing and separating condensable and non-condensable vapors, said pollutant control system including at least one direct contact heat exchanger for bringing the flue gas into intimated contact with a cooling liquid to produce a pollutant-laden liquid stream and a stripped flue gas stream containing condensable and non-condensable gases, said pollution removal system including a discharge for discharging said pollutant-laden liquid stream at least one heat exchanger and compressor for receiving the stripped flue gas stream and separating said condensable and non-condensable vapors so that said condensable vapors can be stored, said pollutant removal system also including and a trap for filtering and accumulating non-condensable vapors before said flue gas is exhausted to the atmosphere.
