Is explosion protection necessary in the ammonia solution area?
Thread Content
Is it necessary to consider explosion protection in the ammonia solution area? I’ve seen many people asking this question; could everyone help me analyze it?
It's needed. . . . . . . . . . . . . . . . . . .
Take a look at the explosion-proof zone classification diagram; it seems that explosion protection is required
I have been pondering this issue for many years. No evidence has been found that ammonia requires explosion protection. But everyone knows that ammonia can explode. Generally, those who insist on explosion prevention can be divided into three categories: one is that \"in our facility, all systems dealing with ammonia are designed in accordance with explosion prevention principles.\"” ； One is “It’s better to execute by mistake than to let one escape.”” ； Another option is that \"explosion-proof equipment can prevent ammonia corrosion – why not use it?\" ”
However, ammonia is still included in Appendix C, classified as IIA level
I hope some experts can explain the intention behind the standards
Has no one answered the questions about floors 7-8? I have the same doubts. Can the revision notes for version 2.0.26 be used as standard provisions?
All those I’ve seen are designed to be explosion-proof.
