Equilibrium concentration profiles of species in CO2-alkanolamine-water systems

Equilibrium concentrations of species and gas loading in aqueous solutions of alkanolamine loaded with CO2 are being compared with predicted profiles obtained from the Deshmukh-Mather Model. A new technique is being proposed based on titration using a base, NaOH, to determine the concentrations of t...
