Zhenhai Refining and Chemicals Million Tons of Ethylene Projects Successfully Drived

At 23:28 on April 20th, Zhenhai Refining & Chemical Co., Ltd.'s 1 million-ton/year ethylene project leading device, the ethylene cracker, produced qualified ethylene, marking the current largest scale, most technologically advanced, and highest localization ethylene project in China. A successful drive drove the end of Zhejiang's history of no ethylene industry. Zhenhai Refinery also has 23 million tons of crude oil comprehensive processing capacity and 1 million tons of ethylene production capacity since then, becoming the largest integrated refining and chemical company in China.
Zhenhai Refining & Chemical Co., Ltd.'s 1 million-ton ethylene project is a national key construction project with a total estimated investment of 23.497 billion yuan. The project started construction in November 2006 and completed in mid-December 2009. In three years, this project has created the largest domestic ethylene engineering project with the largest scale, the highest localization rate, the least management of owners, the continuous construction after the start of large projects, the shortest construction period, and the time for the delivery of qualified products in ethylene crackers. The shortest and so many new records.
In terms of process technology, most of the devices in the project use domestically produced technologies. Among them, six sets of devices such as pyrolysis gasoline hydrogenation use Sinopec's own technology. In the equipment and equipment, the localization rate of ethylene equipment reached 78.03%, which is the highest domestically produced rate of domestic million-ton ethylene equipment. A total of 13 sets of large-scale equipment in the entire project have been listed as major national equipment major research projects and key promotion applications. All of the domestic research projects have achieved independent design, independent manufacturing, and independent installation.
The total environmental protection investment of Zhenhai Refining & Chemical Ethylene Project is nearly 1 billion yuan. The project adopts clean raw materials and chooses clean technology. After the production, the company's major pollutants, such as sulfur dioxide, have reached the industry's leading level. The project's comprehensive energy consumption for ethylene is 546.5 kg/t, the industrial water reuse rate is over 98%, the reuse rate of condensed water is over 70%, and the power station waste water achieves “zero emissions”, all reaching the international advanced level.
According to theoretical calculations, after the project is put into production, it can increase annual sales of RMB30 billion and drive more than RMB100 billion in downstream industrial output value, which will have a major impact on the Zhejiang economy and become a new “engine” for regional economic development, marking Zhejiang Province, Sinopec and Ningbo City have taken an important step in building Ningbo's national petrochemical industry base.
