How to handle a fire caused by a leak in the temperature gauge of a hydrogenation reactor
Thread Content
There was a leakage issue with the temperature gauge in the main reactor after it started operating; a seal has been installed, and there is no leakage at present. I would like to ask what should be done in case of a leak? The reactor temperature is around 300 degrees, so it’s probably not possible to pour water directly on the equipment, right? The main concern is that the temperature of the hydrogen flame is high enough to damage the equipment. If this does happen, I would like to ask everyone for advice on how to deal with it Emergency pressure relief and nitrogen displacement – is it enough time?
Strengthen inspections and prepare accident response plans
Activate emergency pressure relief to reduce temperature and flow rate
This can only be handled by shutting down the system; working under pressure is unsafe.
In the event of a leak in high-pressure equipment, pressure relief is the only solution; putting people first and safety first
For hydrogen-handling high-pressure equipment, working under pressure is very dangerous; it is advised not to take risks – it is safer to shut down the equipment for maintenance.
Is there high-pressure steam nearby that can be used to extinguish the fire?
First, it’s necessary to relieve pressure, and then carry out cooling. I agree quite a bit with what was said above regarding the use of high-pressure steam for cooling.
If a leak leads to a fire, immediately use steam to extinguish the fire, relieve pressure in the reaction system, shut down the reaction heating furnace, stop feeding material into the reactor, and stop the circulating hydrogen compressor. Once the pressure in the reaction system drops to around 0.2–0.4 MPa, close the emergency pressure relief valve. Fill the reaction system with nitrogen to keep the pressure at the leak site from dropping too low, thereby preventing backfire, and wait for the fire department to handle the situation.
