| 概要 | Sequestration of liquid CO2 in the intermediate depth ocean has been considered as a means to reduce the atmospheric concentration of the greenhouse gas and to mitigate global warming. The dissolution behavior of CO2 in pure or seawater was investigate under high-pressure and low-temperature conditions in the intermediate ocean. Under these conditions, the CO2 clathrate hydrate film was formed at the interface between CO2 and (sea) water. The hydrate film has been considered to affect and decrease the dissolution rate. The LIF technique was used in the experiments. LIF intensity showed the pH of CO2 dissolved water, while the CO2 droplet itself did not illuminate. Therefore, we could know the dissolution rate of CO2 and the nonuniform two-dimensional CO2 concentration distribution during the CO2 dissolution, with or without the CO2 hydrate film, in pure or seawater. |
