Interruption of fresh hydrogen supply to the hydrogenation unit
Thread Content
What should be done when the supply of fresh hydrogen to the hydrogenation unit is interrupted?
After a disruption in the fresh hydrogen supply to the hydrogenation unit, the hydrogen supply system should be inspected immediately to determine the cause of the interruption. It could be an issue with the hydrogen source or a equipment malfunction, etc. Then, make repairs or adjustments based on the specific causes to ensure safe production. Before resolving the issue, it may be necessary to pause related operations to avoid security risks. At the same time, inform the relevant personnel, and keep records as well as carry out subsequent monitoring. .
What are the main key processes that need to be carried out?
The main key actions include: 1. Immediately shut down the hydrogenation unit to ensure system safety. 2. Check and determine the cause of the hydrogen supply interruption; it may be related to supply issues, pipe blockages, or equipment failures. 3. Quickly repair the fault or adjust the equipment to restore hydrogen supply. 4. Perform a security check before restarting the system to ensure that all components are functioning properly. 5. Document the events and handling processes, analyze the causes, and prevent similar situations from occurring in the future. 6. Inform the relevant management personnel and operators to ensure accurate information transmission. .
Did the robot answer? Saying it is the same as not saying anything
That kind of response is equivalent to no response at all. Handling problems in that way is like shouting slogans – there are no actual measures or strategies, and it’s possible that it was a robot that provided the answer
1. Quickly close the waste hydrogen discharge valve. 2. Increase the ratio of three returns to one for the new hydrogen compressor, and strive to keep the compressor running. 3. The system pressure will drop rapidly. 4. Reduce the feed valve opening to prevent a drop in pressure and an increase in feed volume. 5. Control the reaction temperature; if it cannot be restored promptly, cool it down as soon as possible. 6. Pay attention to changes in the water injection volume to prevent excessive pressure and a subsequent increase in water injection. 7. Change the fractionation section to a cold long-cycle system. Reduce hydrogen consumption.
The system pressure will drop rapidly; what measures should be taken to control it
1. Reduce the reactor inlet temperature； 2. Stop the feed pump and cease operations of the circulating hydrogen desulfurization tower ； 3. Shut down the new hydrogen generator urgently, keep the circulating hydrogen generator operating normally to ensure system circulation ； 4. If the supply of new hydrogen cannot be restored for an extended period, follow the normal shutdown procedures.
System pressure will decrease, and the absence of hydrogen at the compressor inlet will cause overheating between the compressor stages. The return line can be turned up at this time
