天然气作为一种清洁、高效的能源,近年来在缓解我国能源紧张方面扮演着重要角色。随着天然气在我国能源消费结构中所占比例的不断增加,必然需要发展经济的天然气储运方法。以天然气水合物方式储运天然气与传统的储运天然气方式相比,有着经济、安全等优势,是发展新型天然气储运技术的研究重点。本文概括了目前天然气主要的储运方式,并对其进行了经济性和优缺点的比较,重点介绍了水合物储运天然气的研究现状,最后提出了一种新型的采用压缩式制冷循环的天然气水合物制备系统,该系统具有结构简单、储运效率高等优点。
As a clean and efficient energy source, natural gas plays an important role in alleviating the energy shortage in our country in recent years. With the increasing proportion of natural gas in China’s energy consumption structure, it is inevitable to develop an economical natural gas storage and transportation method. Natural gas hydrate storage and transportation compared with the traditional way of storage and transportation of natural gas, with economic and security advantages, is the development of new natural gas storage technology research focus. This paper summarizes the main modes of natural gas storage and transportation at present and compares its economy with advantages and disadvantages. The current research status of natural gas hydrate storage and transportation is introduced. Finally, a new type of natural gas with compression refrigeration cycle is proposed Hydrate preparation system, the system has the advantages of simple structure, high storage and transportation efficiency.
