International ClassesF17C 005/02F25J 001/00 C01B 031/20 AbstractA method is provided for producing CO2 hydrates. In the subject method, CO2 is first dissolved in water to produce a CO2 hydrate precursor. The CO2 hydrate precursor is then mixed with CO2 gas, resulting in hydrate production. Between the first and second steps, the CO2 hydrate precursor may optionally be cooled to at least 0° C. and/or CO2 hydrate nuclei may be introduced into the CO2 hydrate precursor. The method is carried out in a continuous hydrate production reactor. The subject method finds use in sequestering CO2 gas emissions in the form of hydrates, where the hydrates are deposited in high pressure, low temperature environments, such as in the ocean at depths greater than 1000 m or in subterranean fresh water aquifers. |
