Method for operating a power plant by means of a CO2 process

摘要

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.
