I need advice on what to do in the event of a leak and fire at the flange connecting high-pressure reactors
Thread Content
In a hydrogen-rich and hot oil environment, if a leak leads to a fire, should fire suppression be carried out directly using steam? Just control the fire; extinguish it after pressure is released later? If pressure is released, can the circulator be turned on for a while to lower the temperature before shutting it down? Furthermore, if pressure is released, to what level should it be reduced before introducing nitrogen? Fires always need to be extinguished. When is the right time to put out a fire? If reaction products leak outside, how can we maximize efforts to prevent their spread and protect surrounding equipment?
Cut off the source of leakage and cool down the surrounding containers! Just burn it all down
\"Burn out\" refers to the small flames that leak out, or should one let them die on their own? . .
Our high-pressure reactor developed a leak and caught fire; we first reduced the pressure and introduced steam, then sealed it up right away
This is a good topic; it’s like an accident drill.
Pressure relief, fire extinguishing. Tighten after extinguishing the fire; generally, as pressure decreases the fire weakens, and tightening is carried out once it has been completely extinguished. The circulator does not need to be stopped; it can remain operational until the temperature of the reactor bed drops and becomes controllable, thereby protecting the catalyst.
Release pressure, use fire steam to extinguish the fire, and then tighten it up
The exact procedure is unclear, but the fire cannot be extinguished until the source of the leak is stopped; if the leak continues after the fire is extinguished, it will create an explosive gas environment, which is even more dangerous. Just burn it after it stops breathing
How low should the pressure be? Steam it? Steam cover again?
It’s mainly the reaction products and hydrogen that leak together; so do we have to wait until all the oil is gone?
