Yangzi petrochemical 180000 tons/year ethylene oxide modified in the completion of the project, Yangtze) refining and ethylene oxide fiber production capacity of 186000 tons and 300000 tons of ethylene glycol, become one of the largest similar production device, the optimization of product structure, enhance the olefin chain product profitability, at the same time satisfy the nanjing chemical industrial park users demands for epoxy ethane, It is of great significance to realize the nearby allocation of resources.

In recent years, with the impact of ethylene produced by associated petroleum gas in China and ethylene produced by shale gas in the United States, as well as the low cost impact of ethylene produced by coal in China, ethylene produced by petroleum route is at a competitive disadvantage due to the long-term high crude oil price, and the downstream polyolefin products of ethylene have suffered losses in the whole industry. Optimizing the product structure of the ethylene industry chain and establishing a high value-added industry chain become the inevitable choice. For epoxy ethane/ethylene glycol profitability good market conditions, and nanjing chemical industrial park of epoxy ethane complete industrial chain, Yangtze have many parks epoxy ethane user actual, yangzi petrochemical decided to expand the ethylene downstream ethylene oxide production capacity, with epoxy ethane downstream industry in nanjing chemical industry park nearby docking, and through the safe, convenient pipeline, Upstream and downstream form a long-term, stable supply and demand relationship.

From planning to design and construction, the project has been optimized for a long time. Since the official start of the project, China Global Design Institute, Nanjing Yangzi Design Institute, Sinopec Nanjing Engineering Company, Nanjing Yangzi Engineering Company and other units participating in the project have worked closely together to overcome the difficulties such as small site and tight schedule and realize the high quality project.
