The alarm for the coal chemical industry remains constant

Additional information: On February 23, Shandong Huaxian Installation and Construction Co., Ltd. had two workers enter the S1504 container (an intermediate ash storage tank filter) at a height of 38 meters on the coal chemical processing plant belonging to Zhongyuan Dahuahua Group Co., Ltd. in Puyang City, Henan Province, in order to carry out internal cleaning work. One worker remained outside the container to supervise the operation. As nitrogen was introduced into the pipes connected to the container, the two workers inside suffered poisoning and suffocation. The supervisor noticed this, called for help, and went into the container along with the other two workers to try to rescue them; all of them also fainted inside the container. As a result of the rescue efforts, 3 people died and 1 was injured. It has been learned that Shandong Huaxian Installation and Construction Co., Ltd. is a collectively-owned enterprise and holds a safety production license.

Since the New Year started this year, accidents have been happening non-stop; it seems that extra vigilance is still needed when it comes to safe production!

Addition: Problems currently encountered with several large-scale air separation units used in conjunction with SHELL’s powder gasification process: 1. The Anqing air separation unit with an oxygen production capacity of 48,000 m3/h, manufactured by Hangyang Oxygen, has the main problem of low nitrogen purity in the lower column, which does not meet the design specifications. It is understood that the opening rate of the sieve plates in the lower column was designed to be too high, resulting in an excessive number of openings (the specific parameters are unknown). At present, Hangyang is replacing the lower column in Anqing Petrochemical, with all 76 sieve plates in that column being replaced. 2. The 53,000 m3/h air separation unit for Yongcheng Coal and Electricity Longyu Coal Chemical’s project with an annual methanol production capacity of 500,000 tons was manufactured by Kaikong. The unit started up successfully, but during operation an water ingress incident occurred in the turbine (from Siemens, Germany) that drives the combined air compressor unit, which may cause some damage to the equipment. 3. The 53,000 m3/h air separation unit for Zhongyuan Dahua’s project with an annual methanol production capacity of 500,000 tons was manufactured by Hangyang Oxygen. It was found that during the removal of the scaffolding inside the cold box after installation, one section of it remained connected to the process pipelines. During the trial operation, this scaffolding underwent cold deformation, which caused damage to the process pipelines and led to leaks; repairs are currently being carried out by removing the sand from the affected areas.

Today, safe production has become a priority; safety accidents are not solely due to technical issues, but also to factors such as equipment, production processes, and human error.

Safety really needs to be taken seriously; otherwise, serious problems will arise. Moreover, it’s not enough to just pay attention ideologically; it must be put into practice. Create a positive safety atmosphere and establish a system.

Responsibility is of utmost importance; safety comes first, especially in the chemical industry

Is effective isolation carried out before equipment maintenance? Should an analysis be performed? Do you need to obtain a tower entry permit? Should approval be granted? Are there any preventive measures? Stay vigilant and learn to protect yourself. Progress cannot be put first. All kinds of tickets must be complete.

With the new year arriving, there have been many accidents. Shanghai Coking’s new plant is also set to begin trial production soon; I hope everything will go smoothly.

Having complete tickets ensures procedural completeness, but it does not necessarily prevent accidents. In some organizations, there are indeed quite a few departments and supervisors who sign on the tickets, but in most cases they get the ticket in the control room (which can be considered the field site compared to the office), ask a few questions, and then sign it off without even taking the time to go to the site to verify things themselves ； Some signatories responsible for review and approval are not aware of the content of what is being reviewed or approved, and there is no way to verify it. The first-level reviewer tells the person who submitted the request that there are no issues, so they sign off. Then the second signatory says to the first one, \"If you sign, then I’ll sign as well,\" and so on. In this way, if the first person to handle the ticketing process conducts a thorough inspection and implements the necessary safety measures, then everything will be safe. If that person fails to carry out a proper inspection and is negligent, it’s lucky if nothing happens, but accidents are inevitable! Of course, this is a hypothetical scenario I’ve invented, with the aim of encouraging signatories to exercise proper scrutiny. I hope that relying on just one or two people for safety work permits like this will remain an unrealistic notion in companies, and that such false assumptions won’t come to pass; I truly wish that the warning bells would go unheard!

Nitrogen asphyxiation has occurred in many companies; the key is for everyone to pay sufficient attention to nitrogen. At the same time, appropriate protective measures must be in place. While supervisors fulfill their duties, preventive equipment such as respirators and long-face masks must be readily available. Safety is not the responsibility of just one person; everyone who enters the production area must be accountable for it. There are many companies that do well in this area; you can search for them online, and I hope there will be an opportunity to learn from them or visit their sites. It’s rare to find companies where employees are prevented from entering while the general manager is showing guests around without wearing the required protective equipment; I believe few companies can do such a thing.

It can be said that every time an accident occurs, it serves as a warning to us in the chemical industry. From such incidents, we can learn and identify the causes behind them as well as the appropriate measures to take, and develop contingency plans to prevent such accidents from happening again.

Therefore, no matter what kind of enterprise it is, whether it’s a construction company or the project owner, it is essential to strengthen HSE management – not just going through the motions on the surface, but ensuring that these practices are truly ingrained in everyone’s mindset!

An explosion occurred at a fertilizer factory in Qixia District, Nanjing, causing a 100-meter-long wall to collapse. February 29, 2008, 08:47. Source: Xinhua News Agency Website – Nanjing Morning Post. An explosion at a fertilizer factory in Qixia led to the collapse of a 100-meter-long wall; no injuries were reported. The factory refused to disclose the cause of the explosion. Yesterday afternoon, an explosion took place within the premises of Jinling Petrochemical Fertilizer Factory, located in Ganjiaxiang, Qixia District, Nanjing. Firefighters and factory staff rushed to the scene to control the situation. The residents in the vicinity were only frightened; there were no injuries. During the explosion, a building in the factory complex and a 100-meter-long wall collapsed, and the roofs of several nearby residential homes were damaged. 　　Residents outside the factory area were in shock. “It exploded!” It exploded! ”At around 4:10 p.m. yesterday, a loud explosion disrupted the tranquility in the area surrounding the Jinling Petrochemical Fertilizer Plant located in Ganjiaxiang. Aunt Zhu, who was playing poker, quickly looked in the direction from where the noise came. She saw wisps of white smoke rising from the factory area not far away, and then an explosion was heard from a manhole nearby, sounding like firecrackers going off. 　　When the reporter arrived, the onlookers were discussing loudly among themselves. At this time, police had set up barriers on a road leading into the factory area, and firefighters were discussing strategies with the workers inside the factory. A pungent stench emanated from the site of the explosion; the smell was very strong and caused significant irritation to the eyes and nose. 　　People in the vicinity said, “I was on the second floor at the time; suddenly I heard a very loud noise. I thought it must have been an explosion, and I was very scared. When I looked down, I saw thick white smoke rising from the fertilizer factory area behind us.” ” 　　“On Ganjia Alley, adjacent to the fertilizer factory, a manhole also exploded suddenly; it’s not clear what caused it, and it was really scary. ” 　　A 100-meter-long wall around the factory complex was brought down by the explosion. “We were terrified; we thought a fertilizer factory had been attacked by artillery.” ”A section of the wall in the factory area, which was over a hundred meters long and adjacent to the residential district, was completely destroyed by the powerful wind shock waves. Looking west from the upper floor of a resident’s house, a pile of ruins remained at the scene. 　　Resident Yu Guirong said that at the time of the incident he was chatting with his colleagues when they were stunned by the loud explosion. Their two-story house shook, and then the glass in the windows and doors on the upper floor started to fall down with a clattering sound, which scared the two of them so much that they rushed to escape from the building. 　　The shockwave damaged more than a dozen residential houses. “I thought the houses had collapsed.” ”On the first floor of Gong Fugui’s home, which is located near the entrance of the fertilizer factory, there is a restaurant. Mr. Gong said that at the time of the incident, a dozen people were eating in a private room in the restaurant; suddenly, there were two loud explosions, the glass in the doors and windows was shattered, objects kept falling from the roof, and the building was shaking. The dozen or so guests immediately dropped their dishes and utensils and rushed outside. 　　During the interview, the reporter learned that there are a dozen or so residential houses not far from the fertilizer factory; in some of these houses, the roof tiles were blown off by the shock waves generated by the explosion, some doors and windows were damaged, and the walls of other houses cracked. At resident Liu’s home, the walls of the house were severely cracked. “The ground was vibrating, as if an earthquake were occurring, and the child cried out in fear. ”Liu said that after the incident, a dozen or so citizens asked the fertilizer factory to explain what had happened, but no one gave them any information. 　　There was suspicion of flammable gases in the waste discharge channel. Subsequently, reporters attempted to enter the fertilizer factory to find out the cause of the explosion, but security personnel stopped the reporters’ vehicles, stating that no people or vehicles were allowed to enter the factory premises. The security staff gave no answer regarding the explosion that occurred within the factory premises. 　　Mr. Gao opened a department store on Ganjiaxiang Street, which is right in front of the entrance to the fertilizer factory. “That was close! ”Based on his many years of experience, Mr. Gao suggested that it might have been flammable gases released from the sewage wells in the fertilizer factory that caused the explosion, but it is not possible to determine at this point what type of gas was involved. Some workers on the factory premises also said that an equipment unit in the fertilizer plant exploded, and the gas leak subsequently caused an explosion in a sewage manhole. 　　At 5:38 p.m., many repair workers on the factory premises quickly put on their work uniforms, grabbed their tools, and began working inside the factory, seemingly to clear out the unknown gases in the sewage manholes. By 6 p.m., thanks to emergency efforts, the danger was eliminated. The specific cause of the accident is still under further investigation. 　　Author: Lu Bin/Source: Nanjing Morning Post. The above is a news article reposted by Sohu today; I wonder if it’s true? The Jinling Petrochemical Fertilizer Plant produces hydrogen using Texaco’s water-coal slurry process; if this is true, those in the know are asked to inform us of the cause of the accident, so that similar plants can learn from it!

Thank you to the original poster for providing safety information! Is the frequent occurrence of safety accidents due to rapid economic development? Let’s step outside the usual framework of analyzing security technologies and the causes of accidents, and consider whether the various accidents that have become increasingly frequent in recent years are all due to technical factors Sense of responsibility? Is there bureaucracy? Wait. I don’t think so! The root is at the top. It is closely related to the fact that **’s individual policies are not reasonable enough. . The common people are poor and forced to work in coal mines ； The mine owner has no choice but to give a red envelope to ** ； **It’s frustrating too; one has to report achievements to higher authorities. . . . Think about it, how on earth was such a secure situation created? Thought-provoking.

Another accident caused by inadequate compliance with procedures – it’s tragic!

It is recommended to create a “Disaster Alarm” section to warn everyone using lessons from past disasters!

Leaders at all levels cannot claim to not prioritize safety, but driven by the pursuit of maximum profits, they still take risky actions. The workshop must be profitable; production comes first ； Supply and marketing need to achieve results; everything should serve supply and marketing ； Customer feedback: quality is the most important thing ； Safety first, prevention foremost; those in charge of production must also be responsible for safety. Everyone is accountable for safe production, and there should be a veto power in matters related to safe production Who is Kō? What is the eye? How can safety hazards be addressed when the structure is unclear?

The key is that human life isn’t valued; if it were like in Europe and America, where losing one person costs millions, the situation would be completely different. Of course, it’s best if nothing goes wrong.

It seems that coal chemical enterprises are particularly vulnerable to the hazards of gas poisoning!

Could the causes of the accident be analyzed from a technical perspective, and explained what actions should be taken to prevent such accidents from occurring?
