Environmental Disclosure Information Form of Shouguang Weidong Chemical Co., Ltd

1、 Basic information of the unit
Shouguang Weidong Chemical Co., Ltd. (referred to as Weidong Chemical) was founded in 1956. It was originally a national large-scale backbone salinization enterprise - Shouguang Weidong Salt Factory. It was restructured and renamed on December 27, 2003, and registered on February 2, 2004 with a registered capital of 50 million yuan. It is located in the west of Yangkou Town, Shouguang City. The company currently has a production capacity of 3000 tons/year of bromine, 1700 tons/year of decabromodiphenyl ether, 2000 tons/year of N, N '- ethylenebis (tetrabromo) phthalimide, 5000 tons/year of decabromodiphenylethane, and 5000 tons/year of bromopropane.
VOCS exhaust gas monitoring scheme
The enterprise has formulated a monitoring plan for 2020 and entrusts Shandong Yida Environmental Testing Co., Ltd. to conduct testing once a quarter. The VOCS exhaust gas detection points and project plan are as follows:

Pollution generating facilities
Decabromodiphenylethane production unit 2. Bromopropane production unit 3. Bromine production unit 4. N, N '- ethylenebis (tetrabromo) phthalimide production unit 5. Decabromodiphenylether production unit
Construction and operation of pollution treatment facilities
Decabromodiphenylethane tail gas absorption system with spray absorption for high-altitude emissions; 2. Bromopropane tail gas absorption system includes liquid alkali spraying and ozone oxidation for high-altitude emissions; 3. Decabromodiphenylethane drying tail gas is discharged at high altitude after being treated with bag dust removal. 4. Bromine waste gas is absorbed and discharged up to standard through alkaline spray absorption; 5. Decabromodiphenyl ether exhaust gas is discharged after being sprayed with alkaline solution in the tail gas absorption tower to meet the standard; 6. After the dust is treated with a bag filter and meets the standard, it is discharged into the tail gas of 7, N, N '- ethylenebis (tetrabromo) phthalimide. There is a spray absorption system for high-altitude emissions.
Pollutant emission methods and destinations
Discharged at a height of 15 meters through an exhaust pipe.
