Course content

The subject is offered by agreement every year, next time fall 2019.
The subject comprises the basis for process selection and equipment design in the field of gas cleaning with chemical solvents. The focus will be on removal of CO2, H2S, and water from natural gas, process gases and exhaust gas. Removal of SO2 from flue gases will also be treated. Themes that are covered are: - Treated gas specifications, available technology and unsolved problems. - Rigorous thermodynamic and simplified equilibrium models. - Kinetic models emphasizing the coupling between mass transfer and chemical reaction - Theories for modeling the mass transfer processes. - Cleaning efficiency, energy demand and possibilities for energy integration, selectivity and chemical stability. - Criteria for process selection for specified applications - Equipment and methods for equilibrium and kinetic measurements.

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
- Understand the basic equations need for modeling an absorber and stripper.
- Calculate hydraulic parameters in absorbers
- Calculate mass and heat transfer in absorption and stripping.
- Calculate size of absorber and stripper(Packing)
- Develop the set of equations for kinetic and equilibrium models
Generell kompetanse:
- General understanding of mass and heat transfer processes in contactors where chemical reaction takes place.
