截至今年6月,我国5套煤制烯烃装置产能236万吨/年,预计2017年将达1900万吨/年,将极大缩小我国聚乙烯供应缺口,聚丙烯也将由目前的供不应求达到供求平衡甚至趋于过剩。2012年,我国11个煤制乙二醇试生产或在建项目产能达155万吨/年,但仍不能满足聚酯工业的需求,随着规划建设项目建成投产,预计到2017年,我国煤制乙二醇产能将达400万吨/年,自给率将由25%提高到53%。未来,煤制烯烃、煤制乙二醇将成为我国聚乙烯市场、石油基乙二醇市场的重要力量和补充。
As of June this year, China’s 5 sets of coal-to-olefin plant capacity of 2.36 million tons / year is expected in 2017 will reach 19 million tons / year, will greatly reduce the gap in China’s polyethylene supply, polypropylene will also be the current supply in short supply and demand balance Even tend to excess. In 2012, China’s 11 coal-to-ethylene glycol production trial or production capacity of 155 million tons / year, but still can not meet the needs of the polyester industry, with the planning and construction projects put into operation, is expected by 2017, China’s coal Ethylene glycol production capacity will reach 4 million tons / year, self-sufficiency rate from 25% to 53%. In the future, the coal-to-olefin and coal-to-ethylene glycol will become the important force and supplement to China’s polyethylene market and petroleum-based ethylene glycol market.
