Processing procedure for main air interruption
Thread Content
During normal production, when the main air supply is interrupted and then restored, how are the regenerator pressure and the air reintroduction process controlled to prevent catalyst loss?
What is the size of your catalytic unit? Based on our experience, we keep the pressure in the regenerator at around 100 Kpa; after introducing the main air flow and ensuring normal fluidization in the regenerator, we increase the pressure when it’s time to change the catalyst
What I mean is, during the wind merging process, should the pressure be increased quickly or slowly? How fast can the main air volume be increased?
