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 40oC, desorption at 80oC), 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.
