Approval for the environmental impact assessment of Shaanxi’s 150,000-ton per year methanol-to-polydimethyl ether project / Author/Source: Date: 2016-07-20 Clicks: 47 Recently, the environmental impact report for Shaanxi Industrial Development Group Energy Technology Co., Ltd.’s project to produce 150,000 tons per year of polydimethyl ether from methanol was officially approved. The project is located in the Changqing Industrial Park in Fengxiang, Baoji City, Shaanxi Province. The land acquired for the project covers an area of 120 mu, and the first phase of the project will have an annual production capacity of 50,000 tons of polymethoxymethane. The project covers an area of 42,933.55 m2, with a total construction area of 27,048 m2. The main construction components of the project include a production plant (Phase 1), a tank farm, an office building, along with the corresponding auxiliary facilities, utility systems, and environmental protection measures. Environmental impacts and countermeasures include the use of low-nitrogen burners in the exhaust gas incinerators, ensuring that the flue gas emissions meet the secondary standards specified in the \"Comprehensive Emission Standards for Air Pollutants\" (GB16297-1996). After treatment, the emission concentrations of dust, SO2, and NOX from coal-fired boiler flue gas meet the requirements specified in the \"Emission Limits for Air Pollutants from Key Industries in the Guanzhong Region\" (DB61/941-2014). The production wastewater and domestic sewage are treated at the plant’s wastewater treatment station to meet the secondary standards set out in the \"Comprehensive Wastewater Discharge Standards for the Yellow River Basin (Shaanxi Section)\」(DB61/224-2011) as well as the tertiary standards of the \"Comprehensive Wastewater Discharge Standards\"(GB8978-1996); thereafter, they are sent to the park’s wastewater treatment plant for further treatment. The noise contribution at the factory boundary meets the requirements of the standards for Class 3 sound function areas as specified in the \"Standards for Environmental Noise Emissions at the Boundaries of Industrial Enterprises\" (GB12348-2008) ； The resulting solid waste is classified and disposed of as condoms.
