摘要
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。
The storage and transport of natur al gas in the form of hydrate is a new technology which is being studied and dev eloped at present in the world and which can reduce the storage and transport co st of natural gas and improve its economic effect and safety.Gas hydrate is an e nveloping crystalline compound.One cubic meter of the hydrate can carry 150～180 m 3 of natural gas under standard state.The tremendous gas storage capacity and relatively moderate gas storage condition makes a wide attention.Besides gr eat storage capacity,the storage and transport of natural gas in the form of hy drate is of incomparable superiority in the safety:the hydrate is not easy to bu rn,so the burning and exploding accidents can be prevented and the storage press ure is relatively low (about 4 MPa),So the leakage rate is low when the storage tank is broken.In this paper,the factors affecting the formation of the gas hydr ate is studied and the researching direction of the storage and transport of nat ural gas in the form of hydrate and the problems necessary to be solved in the a pplication and dissemination of the storage technology of natural gas in the for m of hydrate is discussed.
