The simulation and analysis of carbon dioxide supercritical process involves conducting thermal and material balance calculations on the entire process to determine the hydraulic and thermodynamic parameters of each node. Through process simulation analysis, it can not only evaluate the performance indicators of the whole process, but also lay the foundation for the analysis and optimization of carbon dioxide supercritical process. By intuitively simulating the process, the degree of process performance can be judged, and through research on power consumption
