摘　　要：论述了甲醇制烯烃技术路线及其与典型石脑油热裂解制乙烯工艺和成本的比较,国内主要商业化甲醇制烯烃装置,并进一步论证了快速发展的甲醇制烯烃技术对现有乙烯工业的影响;论述了页岩气的储量及近10年来的快速发展,说明了页岩气中的主要成分甲烷、乙烷、丙烷通过具体的技术路线生产乙烯及丙烯等低碳烯烃,进而因为成本优势影响乙烯、丙烯的市场价格。通过近6年乙烯工业中主要石化产品的价格趋势,证明了甲醇制烯烃及页岩气革命所带来的影响,并进一步指出这种影响将在未来的5年内得到加强,同时给出了乙烯装置优化的建议措施。This paper discusses MTO /MTP process,compares MTO / MTP with naphtha pyrolysis for ethylene production in terms of process and cost,introduces main commercialized MTO / MTP units in China,and further demonstrates the impact of the rapidly developed MTO / MTP process on ethylene industry. Also it introduces the reserves of shale gas and its rapid development during the past 10 years,and suggests that some technologies can be used to produce low carbon olefins including ethylene and propylene from methane,ethane and propane,the main com-ponents of shale gas,and then influence the market price of ethylene and propylene due to cost advantages. Based on the price trend of main petrochemical products in ethylene industry during the past 6 years,this paper shows the impact of MTO / MTP process and shale gas revolution on ethylene industry, indicates that this impact will be strengthened in the next 5 years,and presents some recommendations for the optimization of ethylene plant.
