CO2 capture into aqueous solutions of the mixed solvent Cesar 1

Publisher Summary This chapter illustrates experimental data and a simplified vapor-liquid equilibrium (VLE) model for the absorption of CO2 into aqueous solutions of the mixed solvent Cesar 1. The Cesar 1 system has about twice the specific cyclic capacity, measured between 40 and 80°C, compared to 5M Monoethanolamine (MEA). It has almost twice the partial CO2 pressure for a maximum loaded solution at 120°C compared to MEA. The heat of absorption of the two systems is comparable. This should imply both significantly reduced stripping steam consumption and sensible heat loss for the Cesar 1 system making this system a very strong contender to 5 M MEA system in exhaust gas absorption plants.
