Desorption Kinetics of CO2 from Water and Aqueous Amine Solutions

The desorption fluxes of CO2 from loaded aqueous amine solutions and pure water have been measured with a wetted wall reactor. There a well defined liquid surface is exposed to a defined gas atmosphere of CO2 and N2. Henry solubilities and rate constants were measured and compared to literature values to ensure reliable data generated by the employed analysis and experimental setup.Furthermore first desorption experiments under conditions comparable to available literature were performed in order to align our data to already published data. Experimental conditions in this work were mainly chosen for the sake of comparability. In general a good agreement to existing data was found. Therefore our experimental setup and data analysis can be assumed to be valid for further investigations.
