摘要This paper is intended to determine the appropriate conditions for replacing CH(4) from NGH with CO(2). By analyzing the hydration equilibrium graphs and geotherms, the HSZs of NGH and CO(2) hydrate, both in permafrost and under deep sea, were determined. Based on the above analysis and experimental results, it is found that to replace CH(4) from NGH with gaseous CO(2), the appropriate experimental condition should be in the area surrounded by four curves: the geotherm, (H-V)(CO2), (L-V)(CO2) and (H-V)(CH4), and to replace CH4 from NGH with liquid CO(2), the condition should be in the area surrounded by three curves: (L-V)(CO2), (H-L)(CO2) and (H-V)CH4. For conditions in other areas, either CO(2) can not form a hydrate or CH4 can release little from its hydrate, which are not desirable results. (c) 2008 Elsevier Ltd. All rights reserved.
