Abstract: Abstract Knowledge of the conditions at which asphaltenes precipitate from petroleum fluids is useful in the development of enhanced oil recovery scenarios and field development plans. In this work we present a semi-empirical linear model… read more here.

DOI: 10.1016/j.fluid.2019.04.037
Abstract: Abstract This paper presents a modified perturbed chain-statistical association fluid theory (mod-PC-SAFT EoS) obtained by including into PC-SAFT the second-order dispersion term developed originally by Zhang [Fluid Phase Equilibria, 154 (1999) 1–10] for pure components.… read more here.

DOI: 10.1021/acs.energyfuels.7b02790
Abstract: Despite the fact that many publications have dealt with asphaltene onset pressure (AOP) lines during the last 2 or 3 decades, no explicit method for tracing these and other related boundaries from equation of state… read more here.
