Abstract

The equilibrium constant for the formation of carbamate in 3-amino-1-propanol-CO2-H2O system was evaluated at different CO2 loadings, different temperature values, and different amine protonation constant. The studied temperature varied from 298 to 328K in an increment of 10K and ionic strengths up to 1.5M. The variation of the thermodynamic equilibrium constant with temperature was modeled according to the relationship of logK1=1846.8/T-4.4152, while temperature dependency of amine protonation constant was correlated by logK2=2786.5/T+0.5253.
