摘要
文章介绍了国内外煤制天然气技术的发展现状,以及我国新疆、内蒙古、陕西富煤省区的煤炭资源情况和煤制天然气项目建设与规划情况,分析了煤制天然气技术的发展趋势。重点对在低、中、高三种气价情景下我国建设煤制天然气项目的投资、产品成本、经济性进行了计算和分析。在低气价情景下,煤制天然气不能盈利;但在中、高气价尤其是在高气价情景下,煤制天然气项目具有较好的经济效益。结合我国煤制天然气行业发展实际,建议我国合理规划和布局煤制天然气项目;发挥大型石油国企的管道优势,与煤制天然气生产商共同发展煤制天然气;加快二步法成套技术开发,尽快突破一步法工艺,掌握技术主动权,以便在未来煤制天然气发展中占有一席之地。
China's major coal resources are concentrated in three provinces: Xinjiang, Inner Mongolia and Shaanxi. SNG technology is under development worldwide, with ongoing and planned SNG projects. The impact of natural gas prices on the SNG industry can be shown under three different natural gas price scenarios and in the form of capital investment, production cost and market prospects. A project cannot make a profit under a low natural gas price scenario. However the business does well if natural gas prices go up especially to the high price scenario. Some suggestions are made for developing SNG in China.
