The new high performance and no releasing pollutants CO₂ power MATHIANT cycle, operates within the pressure range 1 - 300 bar (4). The paper is concerned with some aspects of CO₂ compression/expansion processes. The thermodynamic and flow processes in high-pressure units of CO₂ compressor and turbine are strongly affected by real gas phenomena, especially in the supercritical region. For the assumed pressure ratios, polytropic efficiencies, cooling and mass flows in each stage it is possible to obtain the final state parameters, compression/expansion work and other performance characteristics based on the real gas model CO₂ properties obtained from Altunin's virial EOS.
