Abstract
In a method of operating a power station plant with a closed or virtually closed CO.sub.2 process, a fuel quantity (21) and oxygen (18) required in this regard for the oxidation are introduced into the cycle for the internal combustion. A recuperator (8) acts on the downstream side of a turbine (2) belonging to the power station plant, at least one heat sink (24) operating downstream of this recuperator before the cycle medium (6) flows back into a compressor (1) which likewise belongs to the power station plant. A partial quantity of the compressed cycle medium (10) is directed into a condensing plant, the liquid CO.sub.2 formed here being disposed of in the best possible way.
