초록
메탄 하이드레이트를 자켓 타입의 교반 반응기내에서 인공적으로 제조하고, 제조된 하이드레이트의 가스 저장 능력을 살펴보았다. 이러한 가스 하이드레이트의 제조 시 반응기내의 제조 조건에 따라서 하이드레이트의 성장과 가스 저장능력은 많은 영향을 받고 있다. 반응조건이 276.65 K이고 600 rpm일때 반응 압력이 4 MPa에서 7 MPa로 증가할수록 유도지체시간은 감소하였고, 생성속도와 가스저장량은 증가하였다. 또한 6 MPa이고 600 rpm일 때 반응 온도가 274.15 K에서 279.15 K까지 증가할수록 유도지체시간은 증가하였고, 생성 속도와 가스저장량은 감소하였다. 그리고 274.65 K이고 6 MPa일 때 교반 속도가 300에서 600 rpm으로 증가하면, 유도지체시간은 감소하며, 생성속도는 증가하고, 가스저장 능력에서는 변화가 없었다.
This paper describes about the storage capacity and the transportation of gas in methane hydrate, which is manufactured in a jacket-type stirred reactor. In the manufacture of the gas hydrate, the formation and the gas storage ability of hydrate are greatly affected by many manufacturing conditions. We found that the induction delay time decreases with increasing reaction pressure (4 MPa to 7 MPa) and hydrate growth rate, and the gas storage ability increases with increasing reaction pressure at 276.65 °K and 600 rpm. The induction delay time increases with increasing reaction temperature (274.15 °K to 279.15 °K) and hydrate growth rate; however, the gas storage ability decreases with increasing reaction temperature at 6 MPa and 600 rpm. Furthermore, the induction delay time decreases with increasing the stirring rate from 300 to 600 rpm; hydrate growth rate increases with the increasing stirring rate; and the gas storage ability is constant within the stirring rate range at 6 MPa and 276.65 °K.
