- Modeling of CO2 vapor-liquid equilibrium in Colombian heavy oil using SARA analysis Oscar Ramirez Carolina Betancur Bibian Hoyos Carlos Naranjo Ingeniería crude pseudo solvent component SARA analysis The solubility of CO2 in Colombian heavy oil was calculated using the Peng-Robinson cubic equation of state and the Lee-Kesler correlations. The crude was represented as a mixture of pseudo-components and for each one of them, the thermodynamic and critical properties were estimated. The results obtained in representing the oil with four, five and six pseudo-components show that all these representations produce similar results and therefore the use of four pseudo-components is sufficient and has a lower computational cost. Excellent results were obtained by comparing the experimental and calculated data. For this system, it is enough to have a complete characterization of the SARA analysis and to use four pseudo-components to adequately model the vapor-liquid equilibrium of CO2 -heavy oil. 2015 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49639089013 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.191 Vol.82
