Method for operating a power plant including a co2 process

Abstract

In a method for operating a power plant by means of a CO2 process, isentropic compression first takes place, subsequently an isobaric heat supply, then isentropic expansion, and finally isobaric heat discharge. The CO2 process broken down here takes place with internal combustion, a fuel (21) and the oxygen (18) necessary for oxidization being supplied. After the charging of the CO2 circuit (23) has been carried out, the excess CO2 formed from combustion is discharged continuously, in that this gas is led through a cooler (14), in which said gas is condensed. In order to dispose of this condensed CO2 (15), there are available here, for example, the possibilities of storing this CO2 on the ocean floor or of introducing the condensed CO2 into a worked-out deposit of natural gas.
