[Haichuan Accident Information] Gas release from Dezhou Chemical Plant in Shandong Province filled the sky with yellow smoke

If you catch illegal emissions or accidental emissions, you will be punished: lol

They rely only on their noses and eyes. This is also the main factor that makes environmental law enforcement difficult.

Yes. In fact, there is no technical problem in collecting evidence now, but the investment is relatively large. Of course, there are also very few issues of localism.

I once went on a business trip somewhere for more than a month and passed a factory every day, and found that it was emitting emissions at regular intervals. Beautiful environment, naked emissions https://bbs.hcbbs.com/thread-1771829-1-1.html (Source: Haichuan Chemical Forum Network)

November 10, 2018 at 16 pm: 35. During the operation of Hualu Hengsheng’s 500,000-ton ethylene glycol production unit, a safety device operated to relieve pressure in the auxiliary equipment of the fourth coupled reactor. The main component was a mixed gas of carbon monoxide, nitrogen oxides, and nitrogen. After emergency processing, 16: 46 The discharge stopped and the production equipment returned to normal. After the accident, the company immediately launched a contingency plan for environmental emergencies and reported it to the local area. * * After reporting to the environmental protection department, the Dezhou Environmental Protection Bureau immediately launched an emergency plan for environmental emergencies, and environmental supervision and monitoring personnel immediately rushed to the scene for disposal. There is an automatic air monitoring station (Hualu Hengsheng small station) set up by the Dezhou Municipal Environmental Protection Bureau about 2km downwind of the discharge point. The online monitoring data shows: 16:00 shows NO2 is 14 micrograms/m3 ； CO is 0.25mg/m3 ； 17:00 NO2 rises to 198 micrograms/m3 (NO2 secondary standard is 200 micrograms/m3) does not exceed the standard ； CO is 0.87mg/m3 (CO secondary standard is 10mg/m3), not exceeding the standard ； 18:00 shows NO2 is 153 micrograms/m3 ； CO is 0.41mg/m3 and has begun to decrease. ； 19:00 shows that NO2 has dropped to 42 micrograms/m3 and has returned to normal. ； Emergency termination at 19:30.

Judging from the reports, it seems that the discharge was caused by the tripping of the safety valve or the rupture disc. It is probably caused by unstable pressure control (the reaction control in the coupling reactor part is more likely to be poor), and the processing was completed in 11 minutes, indicating that the operation was quite skillful, but the Environmental Protection Agency will definitely impose penalties.

I just want to know if it is Hualu Hengsheng.
