What issues should be considered when using pre-filter bag dust collectors or electrostatic precipitators for the desulfurization of flue gas from catalytic cracking units?
Electrostatic dust removal poses a risk of explosion. Try not to use it; if you must, safety interlocks are very important. A survey report from around the year 2000 stated that out of 40, 12 were blown up. Bag filters are very good. Filter materials are very important; it is necessary to choose an experienced technical provider. Several points to note: 1. The flow field should be uniform; there should be no undercooled zones ； 2. Flue gas temperature should not be too high nor too low. It would be ideal to couple it with a feedwater preheater or GGH, so that the flue gas temperature can be adjusted (this is just my guess; it may not make any sense).
