中国煤制天然气长输管道建设现状

Present Situation of Long-Distance Coal Based SNG Pipelines in China

近年来,煤制天然气长输管道得到快速发展,但统计分析资料较少,有必要对总体建设情况进行介绍。对煤制气与煤制天然气的概念进行了区分,介绍具体管道,给出了总里程数,对中国煤制天然气管道现状进行了详细阐述;结合经济形势及国家政策,分析了煤制天然气管道建设存在的问题及发展趋势。总体情况表明,现阶段中国煤制天然气管道的总里程较少,今后的发展受制于多种因素,短期内管道里程将会增长较快,但长远来看仍将处于辅助地位,是常规天然气管道的有益补充。

In recent years, the long-distance coal based SNG pipelines have been developed rapidly in China. But there is few related information. It is necessary to introduce the general situation. The difference between coal gas and coal based SNG is given. Present situation and the length of long-distance coal based SNG pipelines in China are described in detail by giving some pipelines information. According the economic situation and national policy, analysis are conducted on the constrains and development trend of pipelines. It generally shows that the pipeline total mileage is less, the future development is subject to a variety of factors and in short term pipeline mileage will increase rapidly, but in the long run it will remain in the auxiliary position which is a useful supplement to the conventional natural gas pipeline.
