the rumor that the harmful gas was produced by the explosion of Jiangxi Savi has also been clarified

the government will deal with it according to law.

at about 9 a.m. yesterday, the environmental test results showed that toluene, xylene and benzene were not detected in the air of Xinyu urban area, and the air quality reached the national class II standard, which was in good condition

yesterday afternoon, the local government said that people who had left the city had returned to the city one after another, and the people had resumed normal production and living order

the leakage occurred at about 5:00 p.m. local time on October 9. Maleic anhydride leaked from the maleic anhydride storage tank of avant-garde chemical industry. The irritating gas emitted made some citizens feel uncomfortable. After on-site emergency rescue, the leakage was stopped at about 8:00 p.m. and the innovative solutions in the field of high molecular materials were introduced comprehensively. At 10:00 p.m., avantgarde chemical was ordered to stop production in an all-round way for rectification.

harmful gas leakage incident, Xinyu City held an emergency work safety meeting and a city wide work safety meeting respectively. Avant garde chemical management personnel also reviewed the accident at the meeting

Xinyu City requires an in-depth investigation on the maleic anhydride leakage accident of avant-garde chemical industry to find out the cause of the accident, especially the repair of heavy metal pollution in a large area of farmland soil. It is not found out that the demand for light-weight and solid parts is increasing, and the production cannot be resumed until the hidden danger of the accident is rectified in place.

after preliminary investigation, the official explained that at about 5:00 p.m. on October 9, the condenser on the top of the distillation tower of the 8000 ton maleic anhydride unit of avantgarde Chemical Co., Ltd. burst, and the cooling water flowed into the maleic anhydride distillation kettle. At this time, the normal operating temperature in the kettle was 150 ℃ ~160 ℃, and the exothermic reaction between water and maleic anhydride in the kettle produced high temperature, which vaporized maleic anhydride and water, resulting in the pressure rise in the kettle, The flange pad of manhole at the upper end of the rectification tower was broken, resulting in a large amount of maleic anhydride gas leakage

after the accident, Qianwei company failed to report to relevant departments in time, resulting in the accident not being rescued in time

according to public information, avantgarde chemical is located in Xinyu high tech Industrial Park, covering an area of 150000 square meters, mainly engaged in the production of maleic anhydride, resin and paint.
