2-1-4 CO₂ハイドレート生成熱を利用するメタンハイドレートの生産増進法に関する海水を用いた場合のCO₂ハイドレートの相図シフトについて

抄録

Temperature-pressure phase diagram of CO₂ hydrate shifts to low temperature in terms of the salinity. This phenomenon is based on freezing point depression. When the salinity is more than 34 permille, the difference of the shift is become larger. Then, NaCl solution, that is used to use as standard of the seawater, cannot be the standard. Seawater must be used for experiments of CO₂ hydrate.
