What to do if a new hydrogen compressor used for hydrogenation leaks and catches fire?

Handle it according to the emergency plan for hydrogen leaks and fires; remember the safety principles – do not attempt to extinguish the fire until the source of the leak has been properly isolated. Basically, it involves shutting down the machine, closing the inlet and outlet valves, closing the return valve, and releasing pressure if possible.

The operator inside first presses the shutdown button for the new hydrogen machine in the ESD system, and takes action based on the severity of the fire. If the fire is not severe, the circulation machine is started to maintain production; the operator outside, under the supervision of the shift leader, controls the situation, and if the fire becomes too intense, an emergency shutdown is initiated.

First, shut down the system immediately; if it is possible to close the inlet and outlet valves right away, do everything possible to isolate hydrogen from the new hydrogen generator. Hydrogenation shutdown is non-negotiable. Follow the fire emergency plan and pay attention to personal safety

Bro, get out quickly! What are you waiting for? The fire department is on its way to control the fire first; only after that can they carry out isolation and other measures. Otherwise, it will be catastrophic – an explosion is likely to occur.

Shut down immediately; withdraw if the fire gets out of control

A fire in the compressor can occur; anything is possible. Procedures for dealing with this situation: 1. Since hydrogen compressors are critical units, each one is equipped with remote emergency stop controls in the control room, allowing the compressor to be stopped directly from there； 2. Isolate as much as possible from containers that can be isolated, such as hydrogenation reactors, to prevent chain reactions ； 3. Cut off the hydrogen supply, that is, close the hydrogen inlet valve ； 4. Hydrogen compressors generally have an N2 line; by introducing N2 into the compression chamber, the hydrogen content inside the machine can be reduced ； 5. Isolate surrounding equipment to prevent explosions caused by flames burning adjacent devices ； 6. Activate the emergency shutdown plan for the equipment. 7. Inform the workshop supervisors and company management ； 8. Analyze the cause of the accident

Nitrogen is introduced from the top of the inlet, the hydrogen supply is turned off, and the flammable hydrogen is displaced.

Stop the machine immediately to relieve pressure, fill it with N2, control the fire so that it does not spread to nearby critical components and pipelines, cut off the hydrogen supply as much as possible, and only after confirming that there is no more hydrogen leakage should efforts be made to completely extinguish the fire in order to prevent explosions.

In the event of a leak and fire in the new hydrogen compressor, 1) the compressor load is reduced to zero; the compression and inlet/outlet valves are quickly closed, and the unit is depressurized urgently followed by gas replacement, 2) fire-suppression steam and box-type fire hydrants are used for initial firefighting and protection, 3) the operator on duty is notified to carry out emergency cooling and reduction of flow rates, and the production scheduler is informed as well. 4. Immediately dial the emergency numbers of the fire department and the gas safety station. 5. The fire was brought under control, and the backup machine was activated to resume production.

Reply 1# zhxsh6666: I have encountered incidents where the raw gas compressor exploded and caught fire. The new hydrogen compressors are more or less the same, but hydrogen has a wide explosive range; safety must always be the top priority. Moreover, without proper isolation, it is not possible to extinguish the fire. Because it’s safer with a fire. Shut down the machine and close the inlet and outlet valves.
