Résumé

The apparent viscosity and flow regime of CO2 hydrate slurry were investigated with a XL7-100 on-line resonant viscometer. Possible reasons for the viscosity changes before and after the nucleation of hydrates are discussed. In addition, super saturation of the CO2 solution under certain pressure and temperature conditions as well as its density and apparent viscosity were examined. The hydrate's solid fraction and the dissociation enthalpy were evaluated by an on-line Micro DSC system. Real-time coupled multi-electrode array sensor probes were applied to measure the maximal localized corrosion rate of three different materials subjected to CO2 hydrate slurry and saturated CO2 solution in the temperature range of 1 to 18°C and pressure range of 25 to 30 bars. The density of CO2 hydrate slurry was also experimentally investigated and the relation between the density and the solid fraction has been established.
