Limiting carbon dioxide emissions is essential to mitigate climate change. Carbon capture processes can become attractive and scalable with the development of advanced configurations.
The CORT project aims to test and demonstrate novel solvents and advanced process technologies for thermal-driven carbon capture at Aalborg Portland and Ørsted. In thermal-driven carbon capture processes, the specific reboiler duty refers to the energy required to regenerate solvents used in capturing CO₂. Minimizing this is crucial to enhance process efficiency and reduce overall energy consumption, thereby lowering the environmental footprint of the carbon capture process.
The first part of this PhD project aims to analyze the data from Aalborg Portland campaigns that used the CESAR solvent (aqueous aminomethyl propanol (AMP) mixed with piperazine (PZ)). Steady-state points utilizing various advanced process configurations over the campaigns will be determined and their effects on the specific reboiler duty will be investigated over two papers.
After the analysis of the Aalborg Portland data, a rate-based model will be developed for the CESAR solvent based on the determination of its thermodynamic, kinetic, and physicochemical properties. The model will be implemented and validated through Aspen Plus over two papers.
Finally, the steady-state points obtained through the campaigns utilizing the CESAR solvent will be simulated using the newly developed rate-based model. Therefore, the investigated advanced process configurations can be optimized to minimize the specific reboiler duty.
