Abstract

Sequestration of liquid CO₂ into intermediate depth ocean has been considered as a means to reduce atmospheric concentration of this greenhouse gas and mitigate global warming. A number of CO₂ droplets are released into ocean and are diluted. The CO₂ solubility into sea water is very important in order to control the amount of released CO₂ and environmental impact. Under conditions in the intermediate ocean, that is, high pressure and low temperature, the CO₂ clathrate hydrate film was formed on the CO₂ droplet surface. The hydrate film has been considered to decrease the dissolution rate and the CO₂ concentration at the boundary layer on the droplet surface. In the experiments, LIF technique was used. The CO₂ dissolved water emitted intense fluorescence, while the CO₂ itself did not illuminate. Therefore, we could know the shrinking rate of CO₂ droplet diameter accurately. The CO₂ solubility was derived by using the measured shrinking rate. The solubility was investigated qualitatively with some variable parameters, i.e., pressure, temperature and salinity.
