英文摘要
A CO_2 hydrate ball was set up in a high-pressure cell and the hydrate dissociation rate constant was obtained. Next, hydrate formation rate was measured at the CO_2-H_2O interface by using a Micro-DSC. Then, by using the obtained parameters, a two-phase flow simulation with CO_2 hydrate formation was conducted for the sand layer, which simulates the sub-seabed sediments. As a result, the CO_2 storage in the form of gas hydrate is recognized feasible with the storage potential of 18.5-188 billion t-CO_2 and its cost of about 10600 yen/t-CO_2.
