RE: Cyclone failure

Home Forums CatCracking FCC Operations Refractory Lining Damage RE: Cyclone failure



It was found that there was a crack open in the welded portions of the regenerator secondary cyclone. From the historical data it was found that there is no temperature or pressure surge. Can someone  tell the possible reason for this.

One possible answer for the above question is Sigma phase, methalographic replicas on the weld zone will be required to confirm or not sigma phase attack
