Abstract
A process is described for the operation of a gas turbine plant with CO2 as working medium, in which in at least one combustion chamber hydrocarbons are combusted in a CO2 atmosphere enriched with oxygen to flue gases, which largely consist of CO2 and H2O and which are expanded within a turbine stage following the at least one combustion chamber, and are then compressed in a compressor stage and also at least partially condensed in a following condenser, so that at least portions of the CO2 and H2O are liquefied and partially drawn off together with uncondensed flue gas constituents, and so that a main portion, not drawn off, of liquid CO2 is compressed by means of a pump unit, preheated in at least one recuperator stage, and is again supplied to the combustion chamber. The invention is distinguished in that the compressed and preheated main portion CO2 is pre-expanded to a combustion pressure and is supplied to the combustion chamber for combustion with the main portion CO2.
