Zhejiang Petrochemical plans to add 1.4 million tons of ethylene and downstream chemical plants, including polyether polyols and propylene oxide

Latest News: On July 22, Daishan Branch of Zhoushan Ecological Environment Bureau announced the approval of Zhejiang Petrochemical Co., Ltd.’s new 1.4 million tons of ethylene and downstream chemical plant (phase II project product structure optimization) project. .

The project involves a 27/600,000-ton PO/SM plant and a 380,000-ton polyether polyol plant [mainly includes two alkali metal catalyst production lines for polyether polyol (PPG), a
DMC continuously produces polyether polyol (PPG) production line, two polymer polyether polyol (POP) production lines. 】

Construction project composition



Origin of the project

Zhejiang Petrochemical Co., Ltd. (hereinafter referred to as “Zhejiang Petrochemical”) was established in June 2015
On the 18th, it was jointly initiated by Rongsheng Petrochemical Co., Ltd., Juhua Group Corporation, Zhejiang Tongkun Holding Group Co., Ltd., and Zhoushan Marine Comprehensive Development and Investment Co., Ltd. It is a new mixed-ownership joint venture company with private holding and state-owned enterprise participation. The company is mainly engaged in the refining of petroleum products, the production, sales, storage and transportation of chemical products and petroleum products, crude oil import and export trade, etc., and invests in the green petrochemical base of Yushan Island, Daishan County, Zhoushan City
40 million tons/year refining and chemical integration project.

The 40 million tons/year refining and chemical integration project of Zhejiang Petrochemical is divided into the first phase project and the second phase project.
10,000 tons/year ethylene” and other plant production capacity, the main products include: gasoline, kerosene, diesel, fuel oil, petroleum coke, ethylene glycol, diethylene glycol, triethylene glycol, linear low density polyethylene (LLDPE), high Density polyethylene (HDPE), homopolypropylene, copolymer polypropylene, propylene oxide (PO), methyl methacrylate (MMA), acetonitrile, acrylonitrile, butadiene, butene-1, cracking
C5, not hydrogenated
C6-C8, C9, sulfur, etc. The main construction content of the project mainly includes process equipment, storage and transportation engineering, public works, auxiliary production facilities, off-site engineering and supporting engineering in the oil refining area and the chemical industry area. At the same time, Zhoushan Green Petrochemical Base has unified the construction of seawater desalination, power center, base industrial solid waste disposal center (including general solid waste landfill, hazardous waste safe landfill and hazardous waste incineration, etc.) and base sewage treatment plant and other facilities for the project. And other base planning project services. Zhejiang Petrochemical
In the design, construction and operation of the 40 million tons/year refining and chemical integration project, in accordance with the goal of “world-class, green ecology, safety and efficiency” and the concept of circular economy and clean production, the current first phase of the project is supported by a green petrochemical base. The project has been put into trial operation in an all-round way, and some devices and supporting projects of the second phase project have also been gradually put into trial operation.

The first-phase project of Zhejiang Petrochemical Refining and Chemical Integration Project will be independently checked and accepted by the enterprise on December 27, 2021. Relying on the first-phase project of the sewage treatment plant of the project base and the first-phase project of solid waste center incineration, the project will also be completed in 2021.
Self-acceptance was completed on September 29.

The former Ministry of Environmental Protection clearly stated in the EIA approval of the Zhejiang Petrochemical Refining and Chemical Integration Project that “according to the target positioning of ‘world-class, green ecology, safety and efficiency’ and the concept of circular economy and clean production, combined with the impact of the petrochemical base reclamation project on the marine environment The evaluation conclusion, further optimize and adjust the site selection and layout of the factory area, optimize the process route and design plan”, the National Development and Reform Commission also required in the project approval reply that “the construction plan of the second phase of the project needs to be systematically optimized according to the latest changes in the market and technology.” , the leaders of the State Council demanded further “reducing oil and increasing chemical” when they inspected the petrochemical base to adapt to changes in the market environment. To this end, Zhejiang Petrochemical has systematically optimized and adjusted the project. After the optimization of the second phase of the project, the yield of refined oil is
From 41.7% to 29.4%, the ethylene raw material yield increased by 40%. Therefore, after optimization and adjustment, the output of refined oil is reduced and an additional set of
1.4 million tons/year ethylene plant and downstream chemical industry chain, increase high value-added products such as rubber and ABS, and improve economic benefits.

September 1 to October 1, 2020
On July 1, the third central ecological and environmental protection inspection team carried out ecological and environmental protection inspection work in Zhejiang Province. When inspecting the site of Zhejiang Petrochemical Co., Ltd., it was found that the company built a set of 140
The 10,000-ton/year ethylene plant (3# ethylene) violated the “Zhoushan Green Petrochemical Base Overall Development Plan”, the planning EIA and the project EIA approval requirements, and this problem was included in the Zhejiang Petrochemical Central Ecological Environmental Protection Inspector Rectification List as the central environmental protection Inspection finds problems and corrects them. The project has been
In 2021, the local government will impose penalties and require approval in accordance with laws and regulations after completing compliance. At present, the petrochemical base has completed the revision of the planning environmental impact assessment (Zhouhuanhan (2021) No. 63), realizing the planning environmental impact assessment and
3# ethylene and its downstream plant construction projects; in addition, this project has been approved by the State Council to become a reserve project of the “Petrochemical Industry Layout Plan”, and will be completed on June 30, 2022.
In Japan, it passed the expert demonstration meeting to change from reserve projects to planning projects, so it has basically been included in the national industrial planning.
