Abstract: | CO2 disposal in the deep ocean is expected to be an effective option for mitigating the increase in CO2 on the earth. The authors have investigated the behaviour of liquid CO2 using test facilities which can simulate the pressure and temperature of the deep ocean. Phase equilibrium data of the CO2 -seawater system and the conditions of CO2 clathrate formation were confirmed. In addition, the authors measured the pH value of seawater saturated with CO2 at high pressure. The data presented in this paper are considered indispensable for evaluating the possibility of CO2 disposal in the deep ocean |
