IN-SITU STUDY OF THE THERMAL PROPERTIES OF HYDRATE SLURRY BY HIGH PRESSURE DSC
Knowing the enthalpy of hydrate slurry is very essential for energy balance and industrial applications. No direct measurement processes had been developed in this field in the past time. A new experimental method with special device has been developed to carry out on-line measurement of the thermal properties for hydrate slurry under dynamic conditions. With this special device, it is possible to deliver the hydrate slurry to the high pressure DSC (Differential Scanning Calorimetry) directly from the production tank or pipes. Thermal data acquisition will be performed afterwards by DSC. The investigated conditions were at pressure of 30 bar and temperature 0～+7℃. The dissociation enthalpy of CO2 hydrate slurry was about 54 kJ/kg, corresponding 10.8％ of solid fraction. The on-line measurement results for CO2 hydrate slurry give a good tendency to apply this phase change slurry to the industrial refrigeration process.
