Author/Source: Date: 2017-06-30. Views: 24. On June 27, the Shaanxi Provincial Environmental Protection Department officially approved the project to complete the missing elements in the first phase of the comprehensive utilization of coal, oil, and gas resources in the Jingbian Energy and Chemical Park. Approval regarding the Environmental Impact Report for the completion and improvement works of the first phase of the comprehensive utilization project of coal, oil, and gas resources in the Jingbian Energy and Chemical Park of Shaanxi Yanchang China Coal Yulin Energy and Chemical Co., Ltd. – Shaanxi Environmental Approval No. [2017] 283. Shaanxi Yanchang China Coal Yulin Energy and Chemical Co., Ltd.: We have received your company’s request for approval (document No. Shaanxi Yanchang Energy and Chemical [2017] 56). Following the consideration by the Environmental Impact Assessment Review Committee of our department at its 4th meeting in 2017, the approval is as follows: First, the proposed site for the project is located in the Jingbian Energy and Chemical Industry Park. The construction activities will primarily involve using coal and associated gas from oil fields as raw materials to build production facilities capable of producing 1.8 million tons per year of methanol, along with 600,000 tons per year of olefins, 300,000 tons per year of low-density polyethylene/ethylene-vinyl acetate copolymer, and 300,000 tons per year of polypropylene; utility systems and auxiliary facilities will also be constructed as part of this project. The total investment in the project amounts to 14.005 billion yuan, of which 868.28 million yuan is allocated to environmental protection measures, accounting for 6.2% of the total investment. This environmental impact assessment does not cover the accompanying substation; your company should commission a separate environmental impact assessment and submit it to the relevant authorities for approval. Upon review, it can be seen that by fully implementing the various environmental protection measures outlined in the environmental impact report, the adverse environmental impacts of the project construction can be mitigated and controlled. The nature, scale, process, location of the construction project listed in the engineering environmental impact report, along with the environmental protection and pollution control measures to be adopted, can serve as a basis for the implementation of the project. II. The following tasks should be given priority in project construction and operation management: (1) Implement the requirement of \"using new technologies to support older ones\"; before completing the classification and identification of miscellaneous salts, the miscellaneous salts generated during the wastewater treatment process of the first-phase project should be managed as hazardous waste. (II) Boiler flue gas emissions must meet ultra-low emission standards (that is, under a baseline oxygen content of 6%, the emission concentrations of dust, sulfur dioxide, and nitrogen oxides shall not exceed 10, 35, and 50 milligrams per cubic meter respectively). The total amount of pollutants emitted by the project should be kept within 225.288 tons per year for sulfur dioxide, and 886.68 tons per year for nitrogen oxides. (III) Design, construct, and improve the plant’s drainage and wastewater treatment systems in accordance with the principles of separating clean water from polluted water, as well as rainwater from wastewater, to achieve zero wastewater discharge. (IV) Implement zone-based impermeabilization in the factory area, provide impermeabilization for buried pipelines, establish groundwater monitoring wells and conduct regular monitoring to strictly prevent groundwater pollution ； Install environmental accident ponds and initial rainwater ponds of sufficient size to ensure that accident wastewater does not leak out. (5) Hazardous waste generated during the project’s production process shall be collected, stored, and disposed of by qualified entities in strict accordance with the \"Standards for Pollution Control of Hazardous Waste Storage\" (GB18597-2001) and relevant requirements. (VI) Set up standardized pollutant discharge outlets in accordance with **relevant regulations, install online continuous monitoring devices for pollutants, and connect them to the environmental protection authorities. (7) Your company should actively cooperate with the local ** and relevant authorities in carrying out planning controls; no new sensitive facilities such as hospitals, schools, residential areas, or food and pharmaceutical manufacturing enterprises shall be planned or constructed within the health protection distance. III. During the project construction phase, environmental supervision should be carried out, and reports on this supervision should be submitted regularly to environmental protection authorities at all levels; such supervision reports shall be included as part of the environmental protection inspection upon project completion. IV. Project construction must strictly adhere to the environmental protection \"three simultaneities\" principle, which requires that environmental protection facilities be designed, constructed, and put into use simultaneously with the main project itself. After the project is completed, an application for environmental protection acceptance upon completion must be submitted to our department in accordance with the prescribed procedures. Only after passing the acceptance test can it be put into production officially. V. The project owner is the entity responsible for implementing environmental protection measures and making environmental information public throughout the entire process of project selection, construction, and operation. It shall disclose information related to the environmental impact assessment of the project in accordance with laws and regulations, such as those specified in the \"Plan for the Disclosure Mechanism of Environmental Impact Assessment Information for Construction Projects\", and ensure open channels for public participation and social oversight, thereby protecting the environmental rights of those who may be affected by the project. VI. If, after the environmental impact assessment report is approved, there are significant changes in the nature, scale, process, location of the project, or in the measures taken to prevent pollution and ecological damage, the environmental impact assessment report for that project must be submitted for approval again. If more than 5 years have passed since the approval of the environmental impact assessment report and it is only then that a decision is made to commence construction of the project, the environmental impact assessment report must be submitted to our department for re-examination. VII. In accordance with the requirements of the \"Procedures for Supervision and Management of Environmental Protection during and after the Implementation of Construction Projects (Trial)\\", the Yulin Environmental Protection Bureau and the Jingbian County Environmental Protection Bureau are responsible for the supervision and management of this project during and after its implementation. The Provincial Environmental Protection Law Enforcement Bureau oversees and provides guidance on supervision and management during and after an incident occurs. 8. Your company shall, within 20 working days upon receiving this approval, submit the approved Environmental Impact Assessment Report to the Northern Shaanxi Environmental Protection Inspection Center, the Yulin City Environmental Protection Bureau, and the Jingbian County Environmental Protection Bureau for record-keeping, and shall also submit itself to supervision and inspection by the environmental protection administrative authorities at all relevant levels in accordance with the regulations. Shaanxi Provincial Department of Environmental Protection, June 27, 2017. Project for Completing the Infrastructure in Phase I of the Comprehensive Utilization of Coal, Oil, and Gas Resources in the Jingbian Energy and Chemical Park. Project type: Renovation and expansion. Constructor: Shaanxi Yanchang Zhongmei Yulin Energy and Chemical Co., Ltd. Location: Jingbian Energy and Chemical Comprehensive Utilization Industrial Zone, Jingbian County, Yulin, Shaanxi. Scope of construction: Construction of a facility capable of producing 1.8 million tons per year of methanol from coal and associated gas from oil fields (with a ratio of about 1:2 between methanol produced from coal gasification and that produced from the conversion of associated gas; this equates to 600,000 tons per year of methanol from coal and 1.2 million tons per year from oil field associated gas), a 600,000 tons per year DMTO facility for converting methanol into olefins, a 300,000 tons per year polypropylene (PP) facility, a 300,000 tons per year low-density polyethylene/ethylene-vinyl acetate copolymer (LDPE/EVA) facility, two 320 t/h high-temperature and high-pressure coal powder heating boilers, as well as related auxiliary facilities. This project is a renovation and expansion project, to be constructed within the existing plant area and the reserved land on the west side. Once completed, the project will fill the gap in raw materials for the polyethylene and polypropylene plants of the first-phase startup project. At the same time, the operational load of auxiliary facilities such as the coal storage and transportation system, water treatment plant, air compression station, chemical storage area, and acid-base handling station will basically reach the designed levels. Total project investment: 14.005 billion yuan, of which the investment in environmental protection amounts to approximately 868.28 million yuan, accounting for 6.20% of the total investment. Overall process flow of the project and process selection: The coal-to-syngas unit in this project utilizes a pressurized water-coal slurry gasification process. The oil field gas conversion unit employs a single-stage steam reforming process to convert oil field gas into CO+H2. Methanol synthesis is carried out using the Davy process, while the conversion of methanol into olefins uses China’s DMTO process. The LDPE/EVA units use the Basell process developed by Germany’s BASF company, and the polypropylene (PP) units employ Basell’s Spheripol polypropylene process.
