天然气的运输方式及其特点

作为一种清洁、高效的优质能源，天然气在大多数发达国家得到了普遍应用。在21世纪初的几十年中，随着西气东输等工程相继投产，天然气在我国能源结构乃至整个国民经济中的地位将不断提高。运输是天然气供应链中的重要环节，在很大程度上影响着天然气供应和消费的经济性。介绍了天然气的各种运输方式及其技术、经济特点，指出管道是天然气运输的主要方式，各种非管道运输方式是管道运输的有益补充。

Transportation Means of Natural Gas and Their Characteristics

Natural gas has been used widely in most developed countries as a clean and efficient energy sources.For the decades in the early 21st century,with West-to-East Gas Pipeline and other gas supply projects being put into operation, natural gas will play an increasingly important role in the energy system and the national economy of China. As a key link in the natural gas supply chain,transportation has critical influence on the economy of the supply and consumption of natural gas. On the basis of the properties of natural gas, this paper describes the technical and economic characteristics of its transportation means, and concludes that pipelines will be the most popular means for the transportation of natural gas,and other transportation means,including CNG and LNG transportation, will be supplemental to the gas pipeline systems. The information in this paper is helpful for selecting the transportation means of natural gas and for planning gas supply systems.
