Résumé

Precise knowledge of phase behavior of natural gas + aqueous alkanolamine solutions is of interest to design and optimize amine absorption units. In this work, we extend a group contribution with association equation of state to the modeling of phase behavior of mixtures containing water, alkanolamine, and light hydrocarbons (HC). The model parameters were estimated on the basis of binary vapor liquid equilibrium and liquid liquid equilibrium data of the following binary systems: HC + amines, HC + alcohol, water + amine, water + alcohol. The group contribution approach allows the use of an extended databank of experimental data which gives a solid foundation for predicting hydrocarbon solubility in aqueous alkanolamine solutions.
