The accident I saw on Sina just now
Thread Content
At around 9:20 a.m. on December 3, an explosion occurred at a construction site at the Fine Chemicals Plant of Baota Petrochemical Group in the Ningxia Hui Autonomous Region, causing a gas facility to collapse and resulting in 3 injuries and 1 person missing.
Safe production: strengthen supervision, put people first, consider the human-machine-environment balance; accidents are as fierce as tigers!
Explosions are so terrifying; safety comes first
Can it be determined what device it is from the photo?
At the Yinchuan Pagoda Fine Chemicals Co., Ltd. facility, located near Luhuatai in Nanliang Farm in Yinchuan City, an explosion occurred during welding work on a newly built catalytic cracking unit that was already in the final stages of construction; this led to the tilting and collapse of the settler and the regenerator tower.
I guessed it was catalytic cracking yesterday as well, but I didn’t dare to say it. But that catalyst tank is too narrow, and it’s also so tall. The reactor appears to have a very large diameter. How could a newly installed device experience a flash explosion? I want to know what’s going on.
Judging from the picture, it appears to be a coaxial catalytic cracking unit, with a capacity of less than 1 million tons per year. I personally estimate that it might have been fuel gas that entered the regenerator from the auxiliary combustion chamber, where it exploded upon encountering a spark. Such an accident caused the collapse of two structures, and its severity is truly unprecedented.
In the chemical industry, workers are essentially working with their lives at stake; the workplaces must always keep in mind that these substances are flammable, explosive, toxic, and harmful. It is essential to prioritize safety and combine preventive measures with emergency response strategies.
It’s terrifying to watch; what a great device it is, yet one mistake can lead to total failure. How much money and resources have been invested in it! What a shame
It’s the first time I’ve seen a catalytic reactor explode; even before I had heard about such things, I didn’t think it was possible. Today I really learned a lesson. They are all people working in the field of catalysis; such tragic accidents occur, and it’s really important to understand why they happen. We need to be aware of how rare such incidents are. After all, that’s the reality, so colleagues, please be even more careful.
Always keep in mind: \"Safety in production relies on prevention.\" It’s the end of the year now, so everyone must pay close attention to safety measures. . . . . . . .
