What is the role of circulating hydrogen! How to adjust the temperature of the refined reactor bed! What measures should be taken in case of a fire caused by a leak at the hydrogen flange of a reactor quench system! Need an answer quickly! Thanks! !
The hydrogenation reaction is an exothermic reaction, and recycled hydrogen can absorb a large amount of the heat generated by the reaction, thereby preventing excessive temperature rises. Additionally, it helps to maintain the hydrogen partial pressure, ensuring that the reaction can proceed properly. The bed layer in the reactor is controlled by the furnace outlet, while the others are controlled by cold hydrogen. It’s leaking fire – there must be an immediate shutdown! Reduce temperature, reduce volume, relieve pressure
Thanks! Could you explain the specific steps to take in case of a fire?
The second floor is the correct choice. To reduce temperature and pressure, it is possible to lower the pressure by a few levels first; under a relatively safe low pressure level, steam or nitrogen can be used for protection, and maintenance personnel should be contacted to tighten the flanges. Of course, if the fire gets out of control, the only option is to release pressure and shut down the operation.
