Should the material released after a hydrogenation reaction explosion be sent to an explosion venting tank, and how should safety hazards be eliminated once it is in that tank?

Colleagues: Should the materials released as a result of a hydrogenation reaction explosion be sent to an explosion venting tank, and how can safety hazards be eliminated once they are in such a tank? Recently, some experts have suggested that the material released as a result of a hydrogenation reaction explosion should not be sent into an accident tank; there should be no such tanks. They argue that hydrogen enters the explosion containment tank along with the material, and since the tank also contains hydrogen, the risk of explosion caused by hydrogen is not eliminated. How should this be understood? Is this expert’s view correct? I would appreciate it if colleagues could share their insights and opinions. Thank you!

Based on your description, it is an important question whether the material released as a result of the hydrogenation reaction explosion should be sent to the explosion venting tank. According to general safety procedures, materials released as a result of explosion venting should usually not be directly introduced into the venting tank. This is because flammable gases (such as hydrogen) may be released during the explosion venting process; if these flammable gases are directly introduced into the venting tank, it is possible for the gas concentration inside the tank to reach the explosive limit, thereby triggering a new explosion. To eliminate safety hazards, a common practice is to first treat the materials that have undergone deflagration in an appropriate manner to stabilize or degrade them. Cooling, dilution, or other measures can be employed to reduce the temperature and pressure of the material, in order to minimize potential hazards. As for the views put forward by experts, we are unable to determine whether they are correct or not. However, it is very important to respect experts' opinions and engage in brainstorming. It is recommended that you have in-depth discussions with experts in the relevant field to determine the best approach and to ensure that the appropriate safety measures are taken to address the issue of explosions during hydrogenation reactions. .

Generally speaking, the material after explosion venting should not directly enter the explosion venting tank. This is because flammable gases (such as hydrogen) may be released during the explosion venting process; if these flammable gases are directly introduced into the venting tank, it is possible for the gas concentration inside the tank to reach the explosive limit, thereby triggering a new explosion. Therefore, to eliminate safety hazards, a common practice is to first treat the materials that have undergone deflagration in an appropriate manner to stabilize or degrade them. Cooling, dilution, or other measures can be employed to reduce the temperature and pressure of the material, in order to minimize potential hazards. Some experts also suggest that the material released as a result of a hydrogenation reaction explosion should be directed into an accident tank in order to isolate and monitor it. This is because the hydrogenation reaction itself is a process that takes place under high temperature and pressure; in the event of a leak or explosion, the material may contain large amounts of unreacted or partially reacted raw materials, intermediates, and by-products, which can be highly reactive, toxic, or corrosive. If these substances are released directly into the environment, they may cause severe environmental pollution and harm to people. Therefore, to protect the environment and human safety, a viable approach is to transfer the material released as a result of an explosion into an accident tank, so that it can be isolated and monitored, and necessary control measures can be taken. In summary, whether the material released after a hydrogenation reaction explosion should be sent to the explosion venting tank is an issue that requires comprehensive consideration of various factors. It is recommended that you have in-depth discussions with experts in the relevant field to determine the best approach and to ensure that the appropriate safety measures are taken to address the issue of explosions during hydrogenation reactions.
