Shandong Feiyuan Annual Production of 3300 Tons of Nitrogen Trifluoride (Phase II) Project Announcement
1 Overview of Environmental Protection Facility Design, Construction, and Acceptance Process
1.1 Design Overview
The organized emission sources of this project mainly include the exhaust gas from the batching kettle, the cathode exhaust gas from electrolysis, and the low-group exhaust gas from the electrolysis anode. The exhaust gas from the batching kettle of the Phase II project relies on the existing nitrogen trifluoride unit's secondary water washing + primary alkali washing treatment, and is discharged through a 25m high exhaust stack; the cathode gas and anode exhaust gas from the electrolysis workshop are treated by secondary water washing + primary alkali washing and discharged through two 25m high exhaust stacks; the purge gas from the post-treatment precooler, the non-condensable gas from the collection tower, and the exhaust gas from the distillation tower are all treated by the same set of secondary water washing + primary alkali washing and discharged through one 25m high exhaust stack.
1.2 Construction Overview
The environmental protection facilities have been included in the construction contract. Whether the construction progress and funds of the environmental protection facilities have been guaranteed, and whether the environmental protection countermeasures proposed in the environmental impact report (form) and its approval department's approval decision have been organized and implemented during the project construction process.
1.3 Acceptance Process Overview
The nature of the construction project is new construction. In April 2020, Shandong Haimeng Project Consulting Co., Ltd. was commissioned to prepare the "Environmental Impact Report of Shandong Feiyuan Gas Co., Ltd. Annual Production of 3300 Tons of Nitrogen Trifluoride Project". The Zibo Municipal Ecological Environment Bureau issued the "Approval Opinion on the Environmental Impact Report of Shandong Feiyuan Gas Co., Ltd. Annual Production of 3300 Tons of Nitrogen Trifluoride Project" on April 30, 2020, with the document number Zihuan Shen [2020] No. 37. The acceptance was initiated on October 1, 2021, and the company commissioned Zibo Huanyi Environmental Protection Testing Co., Ltd. to conduct self-acceptance of the project. The acceptance monitoring report of Shandong Feiyuan Gas Co., Ltd. Annual Production of 3300 Tons of Nitrogen Trifluoride Project (Phase II) was completed on November 25, 2021, and experts were organized to conduct self-acceptance and propose acceptance opinions on December 9, 2021.
2 Implementation of Other Environmental Protection Measures
2.1 Implementation of Institutional Measures
(1) Environmental Protection Organization and Regulations
The company has established an environmental protection organization, including the composition of the organization and the division of responsibilities; various environmental protection regulations and main contents, including the debugging and daily operation and maintenance system of environmental protection facilities, and the requirements for environmental management ledger records.
(2) Environmental Monitoring Plan
The company has formulated an environmental monitoring plan in accordance with the requirements of the environmental impact report form and its approval department's approval decision.
2.2 Implementation of Supporting Measures
Protection Distance Control and Resident Relocation: There are no environmentally sensitive targets within the health protection distance of this project.
3 Rectification Work
The rectification work needs to explain the various rectification measures taken during the project construction process, after completion, during the acceptance monitoring period, and after the acceptance opinions were proposed, including specific rectification content, rectification time, and rectification effects.
