天然气能源与水合物储运技术研究进展

传统的天然气运输方式有两种,一种是管道输送,但要建立全国范围的连通管网耗资巨大;另一种方法采用低温技术将天然气液化,以液化天然气(LNG)的形式储存、长距离管道或海上油轮运输,但此种技术也存在设备投资大、操作费用高等问题.近年来出现一种新的既安全、又能大幅度降低装置投资和运行费用的天然气储运方法,即将天然气制成水合物(NGH)的形式进行储运.本文着重介绍了天然气水合物储运技术研究进展、发展前景和工业化应用中存在的问题.

The Progresses in the Technology of Natural Gas Storage and Transportation with Hydrate

There are two traditional way to storage and transport natural gases. The one way is to build a huge pipeline wet through country, which costs too much. Another is to liquefy the natural gas at a low temperature and it is transported in the form of LNG, which also takes heavy expense. Recently, there comes a new way that is considered safe and may greatly reduce the cost. That is to transform the natural gas into hydrate for storage and transportation. The paper mainly introduces the progresses in the study of hydrate synthesis and point out the prospect and existing problems in further application of natural gas hydrate.
