Layout of chemical processing equipment and fire separation distances
Thread Content
The design fire protection codes for petrochemical enterprises provide a classification of combustible gases, such as H2 and CO, and specify the layout requirements for facilities using these gases. However, regarding other gases like ClO2, although they do not appear to be combustible gases, they are considered explosive gases with an explosion limit of 10%. May I ask whether such gases can be classified in accordance with the design fire protection codes for petrochemical enterprises? What determines the fire separation distances for equipment using such gases? Thank you!
How can something that’s non-flammable be explosive? I don’t quite understand. An explosion is defined as a violent chemical reaction involving intense burning in a confined space. As I understand it, explosive gases are definitely flammable; I’m not sure if this is correct. I would appreciate it if experts could confirm this for me.
But after checking the properties of ClO2, I found that it is indeed an explosive gas, with a lower explosion limit in air of 10%. However, I couldn’t find any information indicating that ClO2 is flammable; it seems to not react with oxygen
If the situation described by the original poster is indeed the case, then I think it can be classified in accordance with the design fire protection codes for petrochemical enterprises.
We generally follow the petrochemical design fire protection codes, so there should be no major issues
