Hydrogen compressor accident performance
1. The amount of hydrogen suddenly decreases, the pressure of hydrogen drops, and the flow of hydrogen is zero.
2. The temperature at the entrance fluctuates and rises.
3. The system pressure drops.
4. The hydrogen compressor is turned off, and the pressure at all levels is abnormal.
method
1. If the compressor fails, normal production can be restored by switching the standby machine.
2. If all hydrogen generators fail and there is no other hydrogen available, please follow the steps below.
3. The internal operation will change the temperature control of the reactor to manual operation, lower the inlet temperature of the reactor and reduce the feed volume of the device.
4. Notify the external operator to go to the field equipment to change the large cycle operation, open the product and replace the unqualified pipeline valve, and then close the valve.
5. Reduce the amount of steam stripping in the dehydrogenation stripper, stop the pump and the scale inhibitor pump.
6. The circulating hydrogen continues to circulate and maintain the system pressure as much as possible. If the pressure drops to the minimum operating pressure of the circulating hydrogen compressor, the system will be filled with hydrogen to maintain operation.
7. Change the circulating hydrogen to pass through the pipeline, keep the solvent circulating, remove the low gas before removing the gas, and then release the fuel gas from the torch to ensure the normal operation of the desulfurization system.
8. The exhaust valve of the steam generator is opened to prevent the steam from carrying water.
9. If hydrogen is not provided for a long time, please contact the production management department to stop the installation.
