Experimental dissociation data for methane, ethane, propane, and carbon dioxide simple hydrates in the presence of NaCl, KCl, and CaCl2 aqueous solutions with different concentrations of single salt are reported in this communication. The experimental data were generated using a reliable isochoric technique. Some of the experimental hydrate dissociation data measured in this study are compared with some selected experimental data from the literature and the agreements are generally found acceptable, which is a guarantee for the reliability of our experimental technique and the data generated here. All the experimental data are finally compared with the predictions of a general correlation and a thermodynamic model and good agreements between the experimental and predicted data are generally observed.
