dc.description.abstract | $CO_2$ 주입에 의한 석탄층 가스생산거동을 평가하기 위해서는 석탄에 대한 $CH_4$과 $CO_2$의 가스흡착거동을 파악하는 것이 중요하다. 본 연구에서는 $CO_2$ 회수증진공법이 가능한 석탄층 심도내 압력과 온도가 흡착량 에 미치는 영향을 파악하고자 하였다. 이를 위해서 압력은 상압에서 1400 psia의 범위까지, 온도는 $15^{\circ}C$에서 $45^{\circ}C$까지 $10^{\circ}C$ 간격으로 흡착량 실험을 수행하였다. 그 결과, $CO_2$와 $CH_4$ 모두 탄층 압력이 커질수록 흡착량이 증가하는 반면에, 온도가 증가할수록 $CO_2$와 $CH_4$의 흡착량은 일정한 비율로 감소하는 것으로 나타났다. 또한 심도 800m 이하의 범위내에서는 심도가 깊어질수록 $CO_2$ 격리량 및 $CH_4$ 생산량은 증가하지만, 심도에 대한 증가폭은 지속적으로 감소됨을 확인할 수 있었다.In order to asses gas production behavior for $CO_2$ ECBM, the sorption charcteristics on coal are considered to be a key factor. In this study, we have investigated the change of the sorption rate of adsorbed gas as a function of pressure and temperature below the appropriate depth for $CO_2$-ECBM. The experiment were carried out under four different temperatures varying from $15^{\circ}C$ to $45^{\circ}C$, while the coal pressure was varied from atmosphere to 1,400 psi for every temperature. From this results, the sorption rate both $CO_2$ and $CH_4$ increased with increasing the coal pressure. Otherwise, the sorption rate both $CH_4$ and $CO_2$ decreased linearly as the coal temperature increased. From the sensitivity studies on pressure and temperature change, it was experimentally identified that $CO_2$ sequestration rate and $CH_4$ production rate are better at deeper depths below a depth of 800 m in coal seams. However, the results showed continued decline in the increasing ratio of ECBM with formation depth. | en_US |
