Abstract

This short communication confirms that the CP-PC-SAFT equation of state attached by a universal value of k12 = 0.3 is a generally robust estimator of solubility of metallic mercury in liquid and vapor phases of various hydrocarbons at different temperatures and pressures. The considered predictive approach demonstrates that in spite of the divergence of phase behavior in these systems, they exhibit a fundamental regularity, namely the nearly identical ratio between solubility in saturated vapors and liquids expressed in mol/dm3 and plotted versus the reduced pressures of various solvents. In other words, according to this model, the distribution of metallic mercury between saturated vapors and liquids of different compounds actually displays similar patterns of behavior. This observation can be partly confirmed by the novel experimental data.
