The use of heat from the CO₂compression system for production of system heat

Abstract

Abstract. The study presents the concept and computations of the CO 2 compression for the purposes of transport and underground storage of the gas. Cooling between individual stages is needed to reduce the power needed for CO 2 compression. Heat obtained from the cooling process can be used to provide heat to the municipal heat power systems. A design of a heat accumulator for storage of excess heat was proposed in order to improve heat supply safety. The solution proposed in the study allows for heating condensing power units using waste heat from the CO 2 cooling process.
