Environmental impact assessment for the first phase of the 650,000-ton/year integrated chemical new materials project to be approved 2025-03-27 15:39:35 On March 24, the Qinzhou Port area of the China (Guangxi) Free Trade Pilot Zone issued a statement indicating its intention to approve the environmental impact report related to the first phase of this 650,000-ton/year integrated chemical new materials project (major changes). Project Name: Integrated Project for Annual Production of 650,000 Tons of New Chemical Materials (Phase I) (Major Change)
Constructor: Changde New Materials Technology (Guangxi) Co., Ltd.
Nature of Construction: New construction (modification)
Location: North of Gangwan Street, Jingu Area, Qinzhou Petrochemical Industry Park, Guangxi
Land Area: The total planned land area is 201.72 mu (equivalent to 134,478.41 m2), of which the land allocated for this phase is 57,816.13 m2. Total project investment: 1,302 million yuan, of which the investment for this phase is 357 million yuan. Annual operating time: 8,000 hours, approximately 333 days. Production system and staffing: Continuous production; the plant operates on a \"four-shifts, two-shifts\" schedule, with 100 employees assigned to this production phase. Construction period: The construction period for the project is 12 months. Project construction contents: The main construction items for this phase include a production line for the comprehensive utilization of 12,000 t/a of acrylic acid and ester components, a production line for the comprehensive utilization of 25,800 t/a of by-products from vapor-phase rearrangement processes as well as mixed butanol, a production line for the comprehensive utilization of 39,300 t/a of **by-products and C6+ compounds, a production line for cement grinding aids with an output of 56,300 t/a, and a production line for the comprehensive utilization of 31,000 t/a of incinerator slag. In addition, related auxiliary facilities such as fire pump rooms, external pipelines, environmental protection systems, and production management facilities will also be constructed. Upon completion of the project, the total commercial production capacity will be 136,500 t/a. It is reported that in 2022, Changde New Materials Technology (Guangxi) Co., Ltd. planned to invest 1,302 million yuan in the petrochemical park to build an integrated project for the production of 650,000 tons of chemical new materials per year. The project received approval for its environmental impact assessment on June 17, 2022 (Approval No. ZMQJ Huan 21). Following the approval of the project site in May 2023, preliminary work for the project was promptly carried out. The original project plan called for construction in two phases: Phase 1 consisted of four production units for comprehensive resource utilization, carbonyl synthesis, gas-phase hydrogenation, and fine chemicals. The main components of this phase included products resulting from the comprehensive utilization of 95,000 t/a of acrylic acid and ester by-products, 12,000 t/a of caprolactam by-product materials, 62,000 t/a of products related to gas-phase hydrogenation, 15,000 t/a of products related to carbonyl synthesis, and 16,000 t/a of fine chemicals, for a total commercial production capacity of 200,000 t/a. Supporting facilities such as circulating water stations, other auxiliary systems, environmental protection projects, and production management systems are also constructed. The scope of the second-phase construction includes: 390,000 tons per year of downstream products related to propylene oxide, 30,000 tons per year of products related to olefin epoxidation, and 30,000 tons per year of downstream products related to isopropylbenzene; the total commercial production capacity thus amounts to 450,000 tons per year. Additionally, auxiliary facilities, environmental protection systems, and production management systems will be built as part of this phase. Given that this project is characterized by the comprehensive utilization of caprolactam by-products, and as the design of Hengyi’s integrated project and Huayi’s integrated project – from which the project’s main raw materials are sourced – undergoes changes, Changde New Materials Technology (Guangxi) Co., Ltd. has decided to restructure the project. It has opted to cancel the previously approved construction plans, and instead redesign the product specifications and overall layout based on market demands, in order to implement an integrated chemical new materials project that emphasizes the comprehensive use of resources. In November 2024, Changde New Materials Technology (Guangxi) Co., Ltd. underwent re-registration. The components of the project to be carried out under this registration include: the first phase of the project involves a production line for the comprehensive utilization of 12,000 t/a of acrylic acid and ester by-products; a production line for the comprehensive utilization of 25,800 t/a of by-products from vapor-phase rearrangement processes as well as mixed butanol; a production line for the comprehensive utilization of 39,300 t/a of **by-products and C6+ compounds; a production line for cement grinding aids with a capacity of 56,300 t/a; and a production line for the comprehensive utilization of 0,310,000 t/a of slag from incinerators. In total, the commercial production capacity amounts to 136,500 t/a ； Complementary facilities such as fire pump rooms, off-site pipelines and other auxiliary works, environmental protection projects, and production management facilities are to be constructed. The main components of the Phase II project include: a 42,000 t/a gas-phase hydrogenation production line, a 30,000 t/a carbonylation production line, a 36,500 t/a fine chemicals production line, a 20,000 t/a production line for the comprehensive utilization of butanenol by-products, a 300,000 t/a downstream production line for propylene oxide, a 55,000 t/a olefin epoxidation production line, and a 30,000 t/a downstream production line for isopropylbenzene. The total commercial production capacity amounts to 513,500 t/a ； Complementary construction of off-site pipelines, circulating water stations and other auxiliary facilities, environmental protection projects, and production management facilities. The total estimated investment for the project is 1.302 billion yuan, of which Phase 1 amounts to approximately 357 million yuan and Phase 2 to around 945 million yuan.
