On June 28, the first phase of the Zhenhai Base of Sinopec was completed, and the project began to prepare for construction. First phase of the project will start operation at the end of this year, after the production, Zhenhai refining will form 27 million tons/year oil refining and 2.2 million tons/year ethylene production capacity, which is built as the largest base for integration of refining in our country at present, further stimulating downstream industry high quality development, injecting new vitality for state-level economic and technological development zone of Ningbo city and one trillion yuan level green modern petrochemical industry cluster construction and promoting China's petrochemical industry to the medium-high end of the global value chain.

The project is Sinopec's implementation of the strategic deployment of the CPC Central Committee and the State Council on optimizing the layout of major productive forces. The completion of the project is a key node to build four world-class refining and chemical bases in Zhenhai and other areas. The first phase of the project mainly includes the main ethylene project and the supporting projects of the industrial chain. After the safe and efficient construction by nearly 30,000 builders from 55 units such as Sinopec Engineering Construction Corporation, the ethylene project only took 15 months from the approval of the basic design in March 2020 and the start of the on-site civil construction foundation to the delivery at the end of June 2021.

The first phase of the project has a high localization rate. For the first time in China, the "three heart units" (cracking gas compressor, propylene compressor and ethylene compressor) of the ethylene unit of 1.2 million tons/year are all localized, and the indexes of large units are better than international standards. It is the first time to realize the comprehensive localization of one million ton ethylene in the decentralized control system such as chip and operating system, which is a major step forward in the localization of the control system of large equipment. With a high level of digitization, it realizes the synchronous construction and delivery of digital factories and physical factories, and custom-made 5G private network applied to smart factories. Ten thousand 5G base stations will be connected to the ground, and instruments, switches, valves, video surveillance and other equipment in the base will be successively connected to the 5G private network.
