I. Basic Situation of Project Construction
(1) Construction site, scale and main construction content
The Relocation and Expansion Project (Phase I) of Jiangxi Silinco Co., Ltd.is located in the Baishui Lake Industrial Park, Nanchang Economic and Technological Development Zone, Jiangxi Province. This project is a relocation project, with a productionscaleof 1,500 tons/year of MMT, 5,000 tons/year of high-purity manganese chloride (of which 1,200 tons is used as raw material for MMT production), 20,000 tons/year of cetane number improver, and 600 tons/year of carbon monoxide (as raw material for MMT production). To the east of the plant is Huaqiao Road, to the west is Jichang (Airport) Road, to the south is Yingxiong Avenue, and to the north is Yingxiong North First Road.
The company covers an area of 280.2 mu, equivalent to 186,800 m2, with a total building area of 129,917 m2 and a building footprint of 51,178 m2. The main construction contents of the project include one office building (including the R&D building, comprehensive service building, shift building, and central control and analysis building), four production workshops (MMT production workshop, high-purity manganese chloride production workshop, carbon monoxide production workshop, and cetane number improver production workshop), oneboiler house, three warehouses, one machine repair workshop and three tank farms, etc.
(2) Construction process and environmental approval situation
The environmental impact assessment report of the Relocation and Expansion Project of Jiangxi Silinco Co., Ltd. was completed by the Jiangxi Provincial Research Institute of Environmental Protection Science. In September 2013, the Nanchang Municipal Environmental Protection Bureau approved the environmental impact assessment report of the Relocation and Expansion Project of Jiangxi Silinco Co., Ltd. through the document Honghuan Approval [2013] No. 242. The project started in 2013, was completed in June 2016 and put into trial operation.During the construction of the project,the company commissioned the Jiangxi Provincial Research Institute of Environmental Protection Science to carry out environmental supervision of the construction project.After the completion of the project, the MMT production process changed compared with the environmental impact assessment. According to the change analysis made by Nanda Ronghui, these changes do not constitute major changes.
(3) Investment situation
The actual total investment of the project is RMB 220 million, of which the environmental protection investment isRMB 10 million, accounting for4.5% of the total investment.
(4) Acceptance scope
This acceptance is limited to the Phase I project only, including 5,000 tons/year of high-purity manganese chloride; 1,500 tons of methylcyclopentadienyl manganese tricarbonyl, 600 tons of carbon monoxide (MMT)raw materials; and 20,000 tons of cetane number improver.
In the environmental impact assessment approval, the 3,000 tons/yearMCPD (with 1,600 tons/year self-use), 40,000 tons of diesel fuel anti-wear agent, 50,000 tons/year of sec-butyl acetate, 2,000 tons/year of ultra-high-purity nickel nitrate, and 5,000 tons/year of refining catalyst are not within the scope of this acceptance.
II. Construction Situation of Environmental Protection Facilities
(1) Wastewater
This project has implemented the separation of rain and sewage. Rainwater is discharged into the municipal rainwater pipe network through the rainwater pipe network. The sewage mainly consists of process wastewater, floor washing water, vacuum pump wastewater and domestic sewage. After collection, the production wastewater and domestic sewage enter the plant wastewater treatment station(oil separation + neutralization and regulation + air flotation + anaerobic + biological contact oxidation + membrane filtration process)for treatment, and are then dischargedinto the park sewage pipe network, and connected to the Baishui Lake Wastewater Treatment Plant through the municipal sewage pipeline.
(2) Waste gas
The flue gas of the boiler and the heat transfer oil furnace is treated by a cyclone dust collector + water-film desulfurization and dedusting device, and then discharged jointly through one 50 m high chimney. The waste gas generated by the reaction kettles in the manganese chloride workshop is treated by absorption with sodium hydroxide + potassium permanganate solution. The spray drying tail gas is discharged through a 25 m high exhaust stack after cyclone dust collection + spray tower treatment.The tail gas of the MMT continuous distillation section is discharged through a 15 m high exhaust stack after condensation treatment. The tail gas during the concentration and reuse of sulfuric acid in the cetane number improver workshop is discharged through a 15 m high exhaust stack after being absorbed by an absorption tower containing urea solution.The odor gas of the wastewater treatment station is discharged through a 25 m high exhaust stack after alkaline spray + photocatalytic + activated carbon adsorption treatment.
(3) Noise
The enterprise selects low-noise mechanical equipment,rationally arranges high-noise equipment,and at the same time adopts measures such as vibration reduction,sound insulation,and sound absorption,and plants trees in the plant area to form a noise control isolation belt, and strengthens management to reduce the impact of noise on the surrounding environment.
(4) Solid waste
All kinds of solid waste are temporarily stored in correspondingtemporary storageplaces, with corresponding treatment facilities adopted, and are all properly disposed of. Among them, the hazardous wastehas been handed over to Jiangxi Dongjiang Environmental Protection Technology Co., Ltd. for disposal; the domestic waste is collected and disposed of uniformly by the sanitation department.
(5) Other environmental protection facilities
1.Environmental risk prevention facilities
Bermsare set around the storage tanks of the project. Beside the wastewater treatment station, an accident emergency pool with a capacity of 1,250 m3and an initial rainwater collection pool with a capacity of 1,250 m3(also used as a fire-fighting wastewater collection pool) are built.
2.Online monitoring devices
The boiler chimney is equipped with waste gas (monitoring factors: flue gas discharge volume, soot,sulfur dioxide, nitrogen oxides, etc.) online monitoring devices and video monitoring devices. The general outlet of the wastewater treatment station is equipped with wastewater (monitoring factors: discharge volume, COD, ammonia nitrogen,pH value) online monitoring devices and video monitoring devices. The wastewateronline monitoring and monitoring devices have been networked with the pollution source online monitoring system of the Nanchang Municipal Environmental Protection Bureau.
