Abstract: The technical characteristics of ethylene production via ethane cracking route and the industrial situation of this route in China and in the world are summarized and reviewed.In particular, the current situation and future development trend of ethane exports from the United States, and China's current investment status and the related problems in ethylene production projects using imported ethane are analyzed.Ethylene production through ethane cracking route has advantages such as lower production cost, high ethylene yield, less equipment investment, etc.It is the main process route for ethylene production in North America and the Middle East regions.Given the current situation of U.S.A's ethane exports and China's ethylene supply deficit, it is necessary for China's companies to speed up constructing ethylene projects using imported ethane, but there may be also risks such as sophisticated industrial chain and insufficient supply of imported ethane.Chinese enterprises are suggested to invest cautiously so as to prevent from the short raw material supply and the operation risks brought by overheated investment.
