The absorption-based acid gas removal research has focused on various aspects of absorption technologies over the years. Much of the research is currently related to removing CO₂ using absorption technologies, covering experimental work, modelling, process design and simulation studies. The experimental activities focus on developing solvents, characterizing them by measuring CO₂ capacity, vapour-liquid equilibrium, the heat of absorption of CO₂, solvent volatility, physical properties and absorption kinetics, and studying solvent stability and degradation. Modelling and simulation work has focused on thermodynamic and absorption kinetic modelling, degradation modelling, process simulations (steady-state and dynamic), optimization, and techno-economical assessments.

We have been part of numerous national and EU projects and collaborate with industry and research organizations and universities. We are active in Gemini Centre CO₂ Impact, focusing on the collaboration between SINTEF Industry, NTNU and the University of South-Eastern Norway. We also participate in NTNU's strategic research area, NTNU Energy, focusing on the availability of climate-friendly and nature-friendly energy.
 

Lab equipment

The laboratory infrastructure related to absorption studies is part of ECCSEL ERIC, providing researchers outside NTNU access to the infrastructure. A short presentation of the laboratory equipment available for solvent characterization and development can be found here, while more detailed descriptions can be found here: Facility CO₂ absorption.
