Public notice prior to approval of the construction plan for Zhejiang Petrochemical’s 40 million tons/year integrated refining and chemical processing project upgrade initiative. On May 7, 2025, a public notice was issued prior to the approval of the construction plan for Zhejiang Petrochemical Co., Ltd.’s 40 million tons/year integrated refining and chemical processing project upgrade initiative (the 5# unit with a capacity of 4.3 million tons/year for continuous reforming). Project Name: Renovation and Upgrade Project for Zhejiang Petrochemical Co., Ltd.’s 40 million tons per year integrated refining and chemical processing plant (Unit 5: 4.3 million tons per year continuous reforming unit)
Owner: Zhejiang Petrochemical Co., Ltd.
Designer: Sinopec Guangzhou Engineering Co., Ltd.
Location of construction: Yushan Island, Daishan County
Scope of construction: Construction of a new 4.3 million tons per year continuous reforming unit along with associated equipment and facilities, covering an area of approximately 6,400.63 square meters. In accordance with the Urban and Rural Planning Law of the People’s Republic of China and the Regulations on Territorial Spatial Planning of Zhejiang Province, the general design plan is hereby made public. The public display period is from May 7, 2025, to May 17, 2025. If you have any comments, please submit them in writing to the Dai Shan County Natural Resources and Planning Bureau and the relevant departments by May 17, 2025. Entities or individuals who wish to apply for a hearing regarding this project may register with our bureau. Project updates: On December 23, 2024, LANSI Heavy Equipment successfully completed the manufacturing of two reforming reactors for the 5# 4.3 million tons/year continuous reforming unit as part of the renovation and upgrade project for Zhejiang Petrochemical Co., Ltd.’s integrated refining and chemical processing facility; these reactors were then shipped off. The two reforming reactors are the reduction section/reforming reactors 1, 2, and 3 (combined into one unit), and the buffer zone/reforming reactors 4 and 5 (combined into one unit); their total weight is over 1,000 tons. Among them, the three-in-one reforming reactor has a maximum diameter of 3 meters and a height of nearly 100 meters; it is the largest reforming reactor manufactured in China by Lanshi Heavy Equipment after completing the three-in-one reforming reactors for the first and second phases of this project in 2018 and 2020. On July 5, 2024, the Zhoushan Ecology and Environment Bureau (Daishan Branch) accepted the environmental impact assessment report for the renovation and upgrading project of Zhejiang Petrochemical Co., Ltd.’s integrated refining and chemical processing facility (Phase I). An approval decision was issued on July 18, and Phase I is currently under construction. The renovation and upgrading project for the integrated refining and chemical processing facility will draw on proven operational experience to carry out the upgrades; a new No. 3 slurry-bed residue hydrogenation unit and a No. 2 oil residue gasification unit will be constructed, along with the expansion of the existing heavy metal recovery system for oil residue gasification. Upon the implementation of this project, the oil processing routes for Phase 1 and Phase 2 of the refining and chemical integration project will all be optimized to adopt a \"fully hydrogenated route,\" resulting in increased production of PX and ethylene raw materials. This will further enhance Zhejiang Petrochemical’s competitiveness in the field of high-end chemical new materials, and it will also help the entire refining and chemical integration industry achieve \"pollution reduction and carbon emission cuts, as well as synergistic efficiency improvements.\" Project Name: Transformation and Upgrade Project for the Refining and Chemical Integration Facility of Zhejiang Petrochemical Co., Ltd. (Phase I)
Owner: Zhejiang Petrochemical Co., Ltd.
Nature of Construction: Expansion (technical upgrade)
Scale of Construction: Construction of a new 3-million-ton/year No. 3 slurry-bed residue hydrogenation unit (with an expanded catalyst handling facility); construction of a new No. 2 oil residue gasification unit with an effective gas production capacity of 240,000 Nm3/h; expansion of the heavy metal recovery facility for oil residue gasification (with an expanded processing capacity of 300 tons per day); simultaneous expansion of the sulfur recovery facility (with an expanded processing capacity of 8×16 + 30,000 tons per year). Under normal operating conditions, the existing No. 1 delayed coking unit will operate at reduced load ； Other storage and transportation engineering, utility engineering, and environmental protection engineering rely on the existing projects at the petrochemical complex. Operation time: The annual operation time for Unit 3’s slurry-bed residue hydrogenation unit, Unit 2’s oil residue gasification unit, and the sulfur recovery unit is 8,400 hours; the annual operation time for the catalyst support unit of Unit 3’s slurry-bed residue hydrogenation unit and the heavy metal recovery unit associated with oil residue gasification is 8,000 hours. Operational flexibility: The operational flexibility of the 3# slurry-bed residue hydrogenation unit and the 2# oil residue gasification unit is 60%~110%; for the oil residue gasification heavy metal recovery unit, it is 50%~110%. The operational flexibility of the sulfur recovery unit’s sulfur recovery section is 30~110%, while that of the non-hydrogenated acidic water stripping section is 30%~110%. The operational flexibility of the hydrogenated acidic water stripping section is 60%-110%, and that of the non-hydrogenated solvent regeneration section is also 60%-110%. The operational flexibility of both the hydrogenated solvent regeneration unit and the sulfur solvent regeneration unit is 46%-110%. Construction location: Zhoushan Green Petrochemical Base on Yushan Island, Daishan County, Zhoushan City, Zhejiang Province. Land area: This project involves an additional 4.66 hm2 of construction land. New capacity: 109 people. Total investment: approximately 3.2495 billion yuan.
