Course content

The subject is offered by agreement every year. The course comprises the basis for process selection and equipment design in gas cleaning with chemical solvents. The focus will be on removing CO2 and SO2 process gases and exhaust gas. Removal of H2S, and water will also shortly discussed. 

Themes that are covered are:  - Introduction to energy production. Formation of different gas pollutants as well as the most used purification methods.  - Cleaning efficiency, energy demand and possibilities for energy integration, selectivity, and chemical stability.  - Criteria for process selection for specified applications  - Technical challenges in chemical absorption, like requirements for pre-treatment of the gas to be treated.  - Finally, we will discuss the climate challenge in light of international agreements. 

Additionally, each student makes a project work focusing on different aspects of absorption technology. Examples of focus points are - Evaluation of specific industrial cases and feasibility of absorption technology.  - Rigorous thermodynamic and simplified equilibrium models.  - Kinetic models emphasizing the coupling between mass transfer and chemical reaction  - Theories for modeling the mass transfer processes. 

Learning outcome

- Understand the various processes used for CO2-capture at both high and low pressures  - Understand the mechanisms governing energy requirement in absorption processes  - Reaction mechanisms for the various absorbents  - Calculate mass and heat transfer in absorption and stripping.  - General understanding of mass and heat transfer processes in contactors where chemical reaction takes place.
