| Abstract |
Formation and transportation of CO2-hydrate slurry was conducted by circulating saturated water with CO2 through a double-tube type heat exchanger which was cooled down by brine. The inner diameter and circulation length of the heat exchanger were 1 inch and 20 m, respectively. Water in tank was supersaturated by injected CO2 and the operation pressure was maintained at 3,000 to 4,000 kPa with fluid-temperature of less than 9℃. CO2 hydrate mass fraction was calculated based on density of CO2-hydrate slurry mixture. Results showed that the CO2-hydrate slurry could be circulated without blockage for 1 hr. Circulation status of the CO2-hydrate slurry was also visualized. |
