Course content

The subject is offered every other year, next time fall 2011.
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.
