当前世界传统的以石脑油为裂解原料的乙烯工业正遭遇页岩气化工和近代煤化工的严重冲击，页岩气革命为美国和加拿大等国家带来了大量价格低廉的页岩气乙烷和凝析液作为乙烯裂解原料，从而提高了产业竞争力和得到良好的经济效益。建议中国可以借鉴欧洲一些国家的做法，在价格合理的前提下，考虑引进北美乙烷或凝析液作为乙烯裂解原料，进一步提升我国乙烯工业竞争力。%The traditional ethylene industry with naphtha as cracking material is currently seriously shocked by shale gas chemical industry and coal chemical industry. Shale gas revolution has brought a great deal of low-cost shale gas ethane and condensed liquid as cracking material of ethylene to the US and Canada, which improved competitiveness of the industry, and gained high economic benefits. It is suggested that China should learn from some European countries to import ethane/condensed liquid from North America as cracking material at a reasonable price in order to further improve the competitiveness of Chinese ethylene industry.
