Abstract
Method and equipment are disclosed for production of nitrogen and carbon dioxide by a dual phase combustion of a hydrocarbon fuel and air, the exhaust products of the second phase of combustion being treated in a monoethanolamine absorber by which the carbon monoxide is absorbed and the nitrogen and carbon dioxide separated. The first stage of the dual phase combustion is effected in one or more combustion prime movers or engines and the second phase of combustion is effected by the addition of fuel to the exhaust products of the engine or engines; and a compressor is driven by each engine and the separated gases are separately passed through engine-driven compressors.
