Aiming at the synergistic requirements of energy development and carbon emission reduction under the “Carbon Peaking and Carbon Neutrality Goals”, and addressing the “theory-dominated, application-neglected” issue in traditional phase diagram instruction within physical chemistry curricula, this study establishes a tripartite pedagogical framework integrating “theoretical knowledge - technological application - ideological education” based on the national strategic demand for “natural gas hydrate exploitation with CO₂ sequestration”. Through analytical comparison of phase equilibrium curves between CO₂/CH₄ hydrates and CO₂ gas-liquid systems, this work elucidates the thermodynamic and kinetic mechanisms underlying CO₂ replacement-based hydrate extraction and carbon sequestration technologies. By horizontally evaluating current hydrate exploitation techniques and tracking cutting-edge scientific advancements, students are guided to explore ideological topics such as the geopolitical implications of carbon sequestration technologies. The proposed approach pioneers the deep integration of phase diagram theory with national strategic objectives, enhancing students' engineering cognition of multiphase equilibrium principles while cultivating innovative thinking and social responsibility in energy transition. This pedagogical innovation provides a reference pathway for chemical engineering curriculum reform under the “New Engineering Education” initiative.
