Abstract: PetroChina Dushanzi Petrochemical Company took advantage of refining and chemical integration during the special period when the gas separation plant of the oil refining plant was suspended. In order to reduce the loss of olefin emission torches, the means of mixing and blending light hydrocarbons containing high olefin was adopted. Through opening up the light hydrocarbon flow from the refinery to the ethylene plant and combining with utilizing time difference method, the relevant workshops and the competent offices cooperated. These ensured that the light hydrocarbon cracking furnace system vaporized and processed high-olefin mixed hydrocarbons. The entire operation process was clear and the division of professional responsibilities was specific. These helped to reach the goal of safe, environmental-friendly, stabile and controlled operation of the production process.

Key words: refining and chemical integration, high olefin light hydrocarbon blending, steady and controlled production
