Clathrate Hydrates of Cyclohexane plus Hydrogen Sulfide and Cyclohexane plus Methane: Experimental Measurements of Dissociation Conditions

In this work, experimental hydrate dissociation data for the hydrogen sulfide + cyclohexane + water and methane + cyclohexane + water systems are reported in the temperature ranges of (288.3 to 298.2) K and (274.1 to 292.8) K, respectively. The experimental data were generated using an isochoric pressure search method. The hydrate dissociation data for the methane + 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 cyclohexane reported in the literature to identify the hydrate promotion effects of cyclohexane.
