CO2 removal via promoted potassium carbonate with glycine: Solubility measurement at elevated pressure
Potassium carbonate promoted with glycine is considered as potential candidates for CO2 removal process as it demonstrated less energy usage during the regeneration process. Hence, in order to model the process at upscale condition, the loading of CO2 into the promoted solvent is measured at tempera...

Shaarif, M.A. Potassium carbonate promoted with glycine is considered as potential candidates for CO2 removal process as it demonstrated less energy usage during the regeneration process.
