Promoted Strong Bicarbonate Forming Solvents for CO2 Capture

Abstract Effect of different promoters on performance of two bicarbonate forming solvents (HS1 and HS2) was studied in this work and results compared with the performance of 30 wt% MEA and CESAR1 solvents. Based on the results from rapid screening experiments (absorption at 40 o C, desorption at 80 o C), one promoter was selected for further study. Vapor-liquid equilibrium (VLE) and heat of absorption were measured for two solvent systems promoted with the selected promoter.
