Abstract

The absorption performance of a glycine promoted precipitating potassium carbonate (K2CO3) solvent absorption process for carbon dioxide (CO2) capture has been presented using a laboratory scale pilot plant. Glycine has been added as a rate promoter to 40-45 wt.% K2CO3 solutions to examine the enhancement of the CO2 absorption process. The laboratory scale pilot plant has been designed to capture 4-10 kg/hr of CO2 from an air/CO2 mixture at a feed gas rate of 30-55 kg/hr. Performance data of the absorber including pressure drop, holdup and CO2 removal efficiency has been collected from the pilot plant and presented for a range of operating conditions. The addition of glycine was found to imp..
