A thermodynamic model for determination of carbon dioxide solubility and ionic speciation in aqueous alkanolamine solutions

A thermodynamic model for determination of carbon dioxide solubility and liquid phase ionic speciation in aqueous alkanolamine solutions has been presented. The explicit model equation is simple in computation and can be solved using a hand-held calculator, yet its structure is derived from thermody...
