水合物技术在天然气储运中的应用

Application of Natural Gas Hydrate Technology in Storage and Transportation

介绍了天然气水合物(NGH)的结构及物理性质。用NGH运输天然气具有安全、可靠和费用低的优点。研究表明,NGH物理性质稳定,除需要绝热条件外,不需要冷却到平衡温度即可投入大规模储运。分析了典型的水合物生成及分解流程,并将NGH储运方法与液化天然气法进行了经济比较。

This paper introduces the structure and physical property of,natural gas hydrate(NGH).The hydrate has its special clathrate structure.The new method of transporting natural gas using hydrate has its own advantages,such as safe,dependable,low expenses.Therefore,the research on it has been the hot point of the energy exploring in the world.Also,applying the technology of NGH to natural gas transporting is becoming one of the focuses.The article considers that NGH can be stored and transported on a big scale in a steady state without cooling to a equilibrium temperature except an adiabatical condition
