Abstract : Experimental gas hydrate dissociation data for methane + 0.066 and 0.168 mass fractions diethylene glycol aqueous solution, ethane + 0.071 and 0.163 mass fractions diethylene glycol aqueous solution, propane + 0.073 and 0.164 mass fractions diethylene glycol aqueous solution, and carbon dioxide + 0.074 and 0.163 mass fractions diethylene glycol aqueous solution systems are reported herein. The new experimental data have been measured using an isochoric method. All the experimental data are compared with the predictions of a general correlation and a thermodynamic model, and the agreements between the experimental and predicted data are found to be generally acceptable.
