Abstract: A system and method for the abatement of industrial process gases utilizing a combustion engine in combination with an oxidizer. The use of these two elements in conjunction with the use of concentrating equipment where required provides for an energy efficient pollution control method. Means are provided for splitting the gas flow into two streams in any proportion or manner, the first stream mixed with air being passed to a combustion engine, the second being passed to the combustion unit. Means for detecting and controlling are also provided to provide optimal ratio/quantity of gases to the engine in accordance with its requirements.
