In this study, a surrogate model that describes the vapour-liquid equilibrium of CO2 in a flue gas or biogas and an aqueous alkanolamine solution precisely, e.g. monoethanolamine (MEA), is adjusted. A surrogate model is an engineering method used when an outcome cannot be easily determined, hence a model of the outcome is used instead. Most engineering design problems require experiments and/or simulations to evaluate design objective and constraint functions as function of design variables. The vapour-liquid equilibrium data is simulated using the software OLI® which is suitable to work with electrolyte solutions. The system is made of a large number of compounds and chemical reactions which are readily implemented in OLI®. The aim of the study is to determine the distribution of CO2 between the liquid and the gas phases. Therefore, a surrogate model is adjusted to the simulation results. The main variables affecting the carbon dioxide absorption are the type of chemical absorbent, concentrations and the operating temperature. The resulting surrogate model is critically evaluated to check its ability to reproduce satisfactorily the vapour-liquid MEA-CO2-H2O system. The model obtained, together with the mass balances, is useful to design absorption columns simplifying its resolutions.
