In rooms where 25% ammonia solution is used, is it necessary to have explosion protection?
Thread Content
There is a potion preparation room in a power plant where hydrazine is produced using 25% ammonia and sodium hypochlorite. The ammonia is supplied in 2.5 L bottles, while sodium hypochlorite comes in solid form in bags; the process is carried out in an open environment on a batch basis. I would like to ask the experts: is it necessary to establish an explosion-proof area in this case? According to the town gas regulations, areas with more than 8% ammonia concentration require to be designated as explosion-proof zones.
Needed! At such a high concentration, the vapor pressure of ammonia at room temperature is quite significant; in the case of an entire warehouse storing ammonia, any leakage could result in ammonia concentrations high enough to reach explosive levels. Before 2015, an explosion occurred in a company’s tank storing ammonia at a concentration of 25%; the cause was a leak, a malfunction in the ventilation system of the warehouse, and sparks generated by electrical wiring
According to the town gas codes, areas with more than 8% ammonia solution need to be designated as explosion-proof zones. Therefore, for the 25% ammonia solution used, explosion-proof measures are indeed necessary. Open intermittent operation may lead to ammonia leakage into the environment, increasing the risk of explosion. It is recommended to ensure proper ventilation in that room and to strictly adhere to relevant safety regulations in order to safeguard the safety of operators and equipment. At the same time, it is also necessary to consider installing ammonia detection and alarm systems, as well as taking other necessary safety precautions. .
Can this accident be found online? Could you give a search keyword? I’ll organize things and go fight against the client
You can try searching the internet using keywords such as “ammonia leak accident” or “chemical plant safety accident ammonia” to find relevant accident cases and analysis reports. This information may help you provide more arguments and references when negotiating with Party A. At the same time, it is also possible to refer to **or industry-related safety production regulations and standards to enhance the authority of the arguments. .
Thank you, I’ll organize the data to see if I can persuade them.
Both hydrazine and ammonia require explosion protection when used.
It’s not sure whether this can be determined, but in a warehouse dedicated to storing ammonia, or one where ammonia is stored in large quantities, damage to the packaging and resulting leaks can easily cause the ammonia concentration in the warehouse to reach an explosive level. The explosion at that warehouse I’m talking about might not be traceable; it was a minor accident. We published a special article on it at a conference in Baotou, and an expert from Baotou Iron and Steel Company discussed this incident
All outdoor ammonia tank areas require explosion protection as well as online monitors equipped with remote alarm signals. Needless to say, the same goes for indoors. I am from the using unit; three months ago, after a heavy rain, the power supply of the online monitor got flooded and was damaged. The next day, an inspection was carried out by the law enforcement team, and a fine of 10,000 was imposed; rectification was required within a set time limit (the rectification was completed before those officials even left, and no explanations were accepted).
Thank you, I’m still negotiating with the client
