Equilibrium Data of Methyl Cyclohexane + Hydrogen Sulfide and Methyl Cyclohexane + Methane Clathrate Hydrates

Abstract : In this work, experimental hydrate dissociation data for the hydrogen sulfide + methyl cyclohexane + water and methane + methyl cyclohexane + water systems are reported in the temperature ranges of (286.6 to 297.1) K and (274.2 to 290.4) K, respectively. The experimental data were generated using an isochoric pressure-search method. The hydrate dissociation data for the methane + methyl cyclohexane + water system are compared with some selected experimental data from the literature, and the acceptable agreement demonstrates the reliability of the experimental method used in this work. The experimental data for both measured systems are finally compared with the corresponding experimental data in the absence of methyl cyclohexane reported in the literature to identify the hydrate promotion effects of methyl cyclohexane.
