The issue of reactor differential pressure
Thread Content
I read in the documentation that an excessively high differential pressure in the reactor can cause the catalyst to break down and damage the components inside the reactor. I’m not quite sure – what pressure difference causes this phenomenon? Please share your thoughts; extra points for that
There are requirements regarding the pressure difference; if it is exceeded, operations must be halted and the catalyst must be drained, for the reasons you mentioned above
When the pressure difference is high, the forces and pressures acting on the catalyst in different parts of the reactor – such as the upper and lower sections – vary. Generally, a high pressure difference is caused by catalyst coking, sintering of magnetic balls or inert support materials, an excessive amount of fine catalyst particles, or faults with the pressure differential gauge. After ruling out issues related to the instruments themselves, it is recommended to shut down the operation; the extent of the pressure difference depends on the specific circumstances.
A large pressure difference indicates that the catalyst is damaged or clogged. With alarm settings
I think that if the catalyst is broken, it will cause an increase in the differential pressure in the reactor
A high pressure difference indicates severe coking of the catalyst in the reactor. We have encountered situations where the pressure difference in the reactor exceeded 500 Kpa, resulting in the collapse of the catalyst, complete damage to the internal components, and the catalyst turning into powder.
