Questions regarding equipment layout
Thread Content
In accordance with Article 2.2 of HG20546.2-92 \"Engineering Specifications for the Layout Design of Chemical Plant Equipment\", the power distribution room should be located upwind of areas where ammonia gas may escape. I’ve never understood this rule. If the goal is to prevent flammable and explosive gases from entering the switchroom, then many more gases would need to be specified; moreover, ammonia does not qualify as a true flammable or explosive gas, and the equipment in the switchroom should also be explosion-proof.
I’m not in this field, so my answer may not be accurate. Is ammonia highly corrosive to electrical equipment, or does it have other effects on such equipment? I don’t have that information here either; please check earlier to confirm that he isn’t referring to the ammonia production workshop.
Could it be that ammonia combined with water creates a weakly alkaline environment, which has a corrosive effect on electrical devices?
Hehe, LZ, why don’t you try smelling ammonia or staring at it for a few minutes?
Ammonia is classified as a Category B explosive substance; therefore, the distribution room:victory: should be located upwind of areas where ammonia gas may leak.
Agree with the 4th floor! Ammonia is a highly irritating gas; if it leaks, the people working in the electrical room won’t be able to keep their eyes open, let alone carry out their tasks. In the event that they accidentally press a switch or get an electric shock, it could lead to serious accidents.
