Characterization of CO2 Storage by Clathrate Hydrate Crystallization
A potential way of CO2 capture and storage by hydrates is proposed in this paper. The characteristics of hydrate formation is investigated in a small scale dynamic reactor under high pressure conditions from 2-3.5Mpa. Temperature varied between 0.5-4°C. The effect of supercooling degree and overpressure on hydrates formation were discussed. Hydrates formation can be completely finished within 150min and the final pressure-temperature points of system are just on the hydrates equilibrium curve. The induction time increasing with the decreasing of supercooling degree and increase of pressure. It is less than 40min under the experiment conditions.
