利用气体水合物储运天然气是目前世界上正在研究和开发的一项新技术 ,它可以降低天然气储运的费用 ,提高天然气储运的经济性和安全性。气体水合物是一种包络状晶体化合物 ,在标准状况下 1m3的水合物可包含 1 50～ 1 80m3的天然气 ,其巨大的储气能力和相对温和的储气条件备受重视。水合物储运天然气除了储气量大外 ,在安全性方面还有其无比的优越性 :水合物不易燃烧 ,可防止燃烧和爆炸事故发生 ;储存压力相对较低 (4MPa左右 ) ;发生储罐破裂等方面事故时天然气泄露速度慢。研究了气体水合物形成过程中的影响因素 ,讨论了水合物储运天然气的研究方向和推广应用水合物储气技术需解决的问题。
Gas hydrate storage and transportation is a new technology currently being researched and developed in the world. It can reduce the cost of natural gas storage and transportation and increase the economy and safety of natural gas storage and transportation. Gas hydrate is an enveloping crystal compound. Under standard conditions, 1m3 of hydrate may contain natural gas of 150 ~ 180m3. Its huge gas storage capacity and relatively mild gas storage conditions attract much attention. Gas hydrate storage and transportation In addition to large gas reserves, there are also incomparable advantages in terms of safety: hydrates are not easily combustible to prevent combustion and explosion accidents; storage pressure is relatively low (about 4MPa); the occurrence of tank rupture Natural gas leaks are slow during accidents. The influencing factors of gas hydrate formation were studied. The research directions of hydrate storage and transportation of natural gas and the problems to be solved in applying hydrate gas storage technology were discussed.
