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.

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.

[ What is claimed as new and desired to be secured by Letters Patent of the United States is:] [1.]1. A method of operating a power station plant, the power station plant having a compressor unit, at least one combustion chamber and at least one turbine, and a recuperator downstream from the turbine, the method comprising:supplying a cycle medium containing CO.sub.2 and a fuel and the oxygen required for the oxidation thereof in the combustion chamber,conducting the cycle medium from the low-pressure side of the turbine to the recuperator,passing the medium through a heat sink downstream of the recuperator, the heat sink being operated at least at ambient temperature,feeding the medium back into the compressor unit,withdrawing a portion of the cycle medium downstream of the compressor and upstream of the recuperator and conducting the withdrawn portion into a condensing plant, andcontrolling the charging pressure of the cycle processs by extracting any excess cycle medium.
