4. Results and Discussions 4.1. Gas Phase Diagram and Heat Exchange Performance The phase diagram of methane is depicted in Figure 7, revealing its critical point at 46 bar and 190.6 K. Below this critical point, there exists a distinct phase change boundary between the liquid and gas phases, requiring separate treatment for each phase. Conversely, above the critical point, there is no discernible demarcation between the compressible liquid and supercritical state.
