  • Injection behaviors of gas CO_2 with hydrate

抄録

Sequestration of CO_2 to geological formations such as aquifers is considered to be one of possible strategies for the abatement of CO_2 emissions to the atmosphere. Because CO_2 rises upward in underground, one of options to ensure safety is to inject CO_2 into the layer under the seabed. In this case, it is essential to understand CO_2 leakage behavior that leads to whether CO_2 leaked gas could be sequestrated in seawater or not. CO_2 gasifies and leaks from the seabed with hydrate under the high-pressure and low-temperature condition. As injection behaviors of CO_2 gas with hydrate hasn't been researched, we observed injection behaviors of CO_2 gas with hydrate from single-hole nozzle including propagation velocity.
