Abstract: The “Salt-Water System Phase Diagrams” is a core concept in the curriculum for undergraduates majoring in chemical engineering and technology, particularly for those specializing in the salt production and salt chemical industries. In the context of “Emerging Engineering Education” and the “Dual Carbon” background, as well as in alignment with cutting-edge international research, the teaching team at Tianjin University of Science and Technology has introduced salt-water system phase diagrams modified by carbon dioxide (CO2). This innovation enhances the teaching effectiveness and promotes interdisciplinary integration. This paper focuses on case studies involving CO2-carbonized salt-water system phase diagrams to address challenges such as alkali recovery and the separation of sodium and potassium salts. These case studies guide students in solving practical engineering problems and achieving resource utilization of salt lakes through CO2 conversion. This approach significantly broadens students' knowledge in both salt-water system phase diagrams and green chemical engineering, while fostering their innovative thinking and problem-solving abilities in real-world contexts.
