Consequences of abnormal operation of the ****** device: On July 11, 2009, an abnormal situation occurred at a chemical processing plant around 5 a.m., accompanied by a strong, pungent odor and loud roaring noises. The scale of the chemical rain spray has affected several nearby enterprises, as well as a long stretch of road; wherever it reached, all plants and grass died. All 100 mu of fertile land withered, and other areas in the vicinity, including the water treatment plant, were also severely polluted. Among them, the FAW-Volkswagen 4S store and *** Auto Company were severely affected as they were located right next to this factory. All buildings and new vehicles have suffered varying degrees of corrosion, and the employees of the affected companies have endured severe physical and mental harm. We have approached **** on many occasions, but no one has paid any attention ; Reporting the issue to the Management Committee of the Backward Economic Development Zone also yielded no results ; I called the environmental protection agency, and they said they would come and deal with it right away. It’s been over a month now, but not a single person has shown up. By 8 p.m. on July 15, six employees had experienced symptoms such as dizziness and vomiting; hospital tests confirmed that they had suffered from ammonia poisoning, and two of them, whose condition was more severe, were admitted to the hospital. After the incident, the factory did not cease its production activities, nor did it provide comfort to the employees of the affected companies; it continued to spray chemical substances fearlessly, release toxic gases, and create loud noises. Ignoring the safety and health of all the people living in the economic development zone, the relevant authorities failed to take any action to address the consequences of this situation; they simply allowed things to go unchecked. The environmental protection agency was also on the side of the chemical plant, and no one paid any attention to the complaints made by phone. Over 70 employees have to work in such a terrible environment every day – it’s a complete disregard for human life. According to inspections of air quality conducted by authorized environmental monitoring agencies, the ammonia level in the offices was 21 times above the permissible limit, while the ammonia levels in the workshops and outdoors exceeded the measurement range of the instruments, estimated to be over 50 times higher. In the end, all the employees could no longer bear working in an environment filled with highly toxic gases, so they voluntarily went to the office in the development zone to request a discussion with ***** regarding how to resolve this issue. Yet, as employees are after all a vulnerable group, ****’s representative claimed that they were key enterprises at the provincial level, enterprises designated with ** status...; in the end, they simply ignored us. During this process, there were also incidents of security personnel beating people, which is absolutely unacceptable. Here, we appeal to society to help us and show us solidarity, “***to restore our physical and mental health, and to give us back a blue sky.” ”(It is 16:40 on the afternoon of July 16, 2009; 5 days have passed.) *****There is still the reckless spraying of chemical rain, the release of toxic gases that create loud noises; we still have to endure this....)

It’s likely that the gas phase from the synthesis tower is being vented; this shows just how difficult it is to get the plant up and running......

It is very likely that the liquid level in the synthesis tower is high; this is a typical case of granulation outside the tower

Driving in this way, with the device operating in this fashion, is not actually cost-effective. Regarding environmental protection issues, the local environmental protection agencies of enterprises in any place will not take care of them, nor are they able to do so. If it’s a state-owned enterprise that isn’t linked to local taxes, then even if there are no problems, they will still find ways to create trouble for you.

Poster: What are the specific reasons behind this abnormal phenomenon? Do you understand? I hope my colleagues will learn from this lesson.

Regarding the issue mentioned by the original poster, I’m not sure whether this situation occurred only once or has been going on for a long time If this situation persists over a long period, I suspect it is due to a large amount of high-pressure venting, which results in a heavy load on the low-pressure absorption tower and thus an increased amount of venting; this in turn leads to urine being discharged from the low-pressure absorption tower.

This is not allowed, whether in the long term or short term; it merely indicates a weak level of environmental protection in that area. Here, as long as residents make a call, the environmental protection agency will immediately arrive to conduct an investigation, and fines will be imposed right away if there is evidence of violations.

“The term ‘pelletization outside the tower’ is really good; someone has complained about our urea dust, and I don’t understand why.

It seems there’s a problem with the synthesis system; there is a gas vent in the synthesis tower, but I’ve never heard of such a thing before. This kind of situation has occurred when we first started up the synthesis tower here: the gasket on the large cover of the synthesis tower began to leak, and the leakage got worse over time – that’s exactly what happened. When we went to take a look the next day, it looked as though snow had fallen

In the case of CO2 stripping of urea, this phenomenon occurs presumably because when the high-pressure circuit experiences overpressure, in order to prevent further overpressure, the vent valve of that high-pressure circuit may be opened to release pressure, which thereby leads to the leakage of urea. It's just my personal guess, for reference only.
