摘要

Abstract Process for Measuring Recycled Chilled Waste Gas from the Waste Heat Boiler of a Gas Turbine The present invention relates to a process for recycling waste gas from a gas turbine with a waste heat boiler downstream, wherein said waste gas is measured into the supply air stream of a gas turbine so that the temperature and composition of the waste gas can be controlled and thus highly concentrated carbon dioxide (co2) is obtained which can be injected into a storage site so that the carbon dioxide balance for the entire process can be kept low or insignificant. Through a measured recycling of the waste gas, it is possible to lower the temperature in the gas turbine and considerably increase the carbon dioxide content in the waste gas so that after combustion and heat exchange a gas scrubbing will be achieved. carbon dioxide can be recovered and the free oxygen content in the waste gas can be reduced. In another embodiment of the invention, an oxygen enriched gas is supplied as food along with a combustible gas for the combustion gas turbine and then diluted with a waste gas so that the temperature can be kept low despite oxygen enrichment and, after combustion and heat exchange, highly concentrated carbon dioxide is obtained. 1/1
