چکیده مقاله:
Since mixtures containing glycols are very important in oil-gas and chemical industries, modeling of such systems isone of the topics to be considered. The cubic-plus-association(CPA) equation of state(EoS) is employed using twodifferent association schemes for glycols to model liquid density and vapor pressure of pure glycols and vapor-liquidequilibria(VLE) of several binary systems. The performance of two various association schemes compared with eachother and our predictions were generally in agreement with the experimental data available in the literature. Adiscussion about the most appropriate association scheme for glycols is presented and according to the results thatobtained, one of the association schemes introduced as a better association scheme.
