Abstract: As China's refined oil market kept weak in recent years,most of domestic refineries continue to be in a poor economic status.Especially for certain fuel-oriented refineries,which have an average refining scale no more than 8 million tons per year and have limited amount of light hydrocarbon resources available from themselves,they face obvious limitations to extend their chemical industry chain by relying solely on their own light hydrocarbon resources and are difficult to form a large-scale chemical production capacity and improve their operation economy.With the advancing technology in recent years,the scale of light hydrocarbon utilization units in such medium-scale refineries can be effectively increased by combining their own light hydrocarbon resources with external light hydrocarbon resources.As a result,diversification and large scale of chemical product schemes can be realized,thus effectively improving the operational flexibility and achieving significant improvement of enterprise benefits.Taking a typical 8 million tons/year fuel refinery in China as an example,this paper introduces three typical cases that China's refineries extend the chemical industry chain by producing ethylene through steam cracking of light hydrocarbons from both their own refining units and other external light resources.
