Abstract
Aqueous alkanol amines or their blends are used as solvents for acid gas removal in most amine scrubbing processes. In this study, we selected six polyamines with three amine groups that have sufficiently high boiling temperatures and evaluated their potentials as CO2 capture solvents by investigating the CO2 vapor–liquid equilibrium, mass transfer rate, viscosity, and thermal stability. Among the tested polyamines, two were chosen and mixed with 2-(butylamino)ethanol and piperazine (PZ) to compensate for the inferior properties of each polyamine, and their properties were investigated. As a result, aqueous 2,6,10-trimethyl-2,6,10-triazaundecane mixed with a small amount of PZ showed a great potential as a new CO2 capture solvent in that it has a quite high absorption rate and thermal stability and a low reboiler duty.
