Thermal Energy and Process Technology
Efficient thermal energy and separation processes make a decisive contribution to energy supply and energy consumption worldwide. Research into innovative approaches to energy generation using supercritical CO₂ as a working medium as well as energy-optimised phase contacting and reducing the size of separation equipment are of crucial importance for resource-saving energy generation and use.
Carbon dioxide above the critical point (31°C, 73.8 bar) has a number of advantages when used in thermodynamic cycle processes. These cyclic processes achieve higher efficiencies and a significant reduction in the size and complexity of the individual components. This enables the more efficient utilisation of industrial (waste heat), geothermal and solar heat sources as well as thermal energy storage systems.

System analysis in process engineering involves evaluating how different components within a process interact dynamically to achieve efficient and reliable operation. In addition, system analyses serve to determine the economic efficiency and sustainability of technical-chemical processes for different operating scenarios and production environments.
