The compression process is one of the most energy-consuming stages of the entire cycle of the carbon dioxide capture and storage. a reduction in the energy consumption of this process may have a significant impact on the overall net efficiency of electricity generation. One method to improve the efficiency of the compression process is to introduce inter-stage cooling, which makes it possible to cause compression to resemble an isothermal process. This paper presents an analysis of the operation of a cooling system of an eight-stage integrally geared compressor working for a 900 MW coal-fired power plant equipped with a CCS system. The research conducted enables rational values of the heat transfer coefficient to be determined for individual inter-stage coolers. a series of calculations is performed in this analysis for different assumptions and for an assumed geometry of the inter-stage coolers. The results obtained allow one to determine both the heat exchange surface area and the pressure drops on the “hot” and “cold” agent sides for individual coolers. Moreover, the presented analysis identifies a number of problems that arise when selecting the configuration and the appropriate parameters of the cooling system.
