This work studied the precipitation behavior of solids in the aqueous solution of potassium sarcosine (KSar) during the CO2 capture process with the concentration of 5m' (mol/kg solution). The effect of precipitation on the CO2 capture capabilities was also studied. The results showed that 5m' KSar gives a comparable result to MEA. The relatively high initial CO2 absorption efficiency combined with the positive effect of precipitation on CO2 absorption rate and CO2 capacity have made the 5m' KSar be a promising solvent for the CO2 capturing process with precipitation.
