What to do if the turbine hydrogen circulation pump stops?
Thread Content
Exactly how should it be done, indoors or outdoors?
The device is shut down. The operator pays close attention to the reaction and distillation systems, as well as the bed temperature and the liquid level and pressure in various tanks, in order to prevent overheating, overpressure, and pressure surges; the reaction system is depressurized completely, while the distillation system switches to hot oil circulation ； For outdoor operations, it is necessary to confirm the interlock actions that occur after the cycle hydrogen compressor is shut down; this includes devices such as the new hydrogen compressor, feed pumps, heating furnaces, and key isolation valves
Check the operating procedures for accident handling; different devices require different approaches
Find out what caused the shutdown; if it’s a gauge malfunction or some other issue that can be resolved promptly, the turbine can be started up while still hot, allowing the plant to resume production； If issues such as process problems cannot be resolved promptly and shutdown is necessary, emergency pressure relief and shutdown must be carried out.
It’s possible to cut off the two circulation paths of feed reaction and fractionation, right?
Reaction pressure relief, fractional distillation cycle – that’s the process for hydrogenation
If the reaction is not intense, it may be possible to avoid pressure relief; in that case, the excess hydrogen can be controlled, while cracking requires pressure relief
Once the circulation machine stops, the entire system shuts down in a cascade: feed supply is halted, the furnace is stopped, the new hydrogen generator ceases operation, and emergency pressure relief is triggered.
