| Abstract: | Corrosion of regenerator flue gas from FCC unit to flue gas equipment,it will result in high temperature catalyst and flue gas leakage,which will seriously affect the daily production of the unit and cause bad consequences to the environment.The corrosion leakage occurred at the sampling port of the regeneration flue analyzer and the expansion joint behind the butterfly valve in a FCCU for 2 years.The corrosion causes,treatment measures and suggestions are analyzed according to the characteristics of the unit and its daily operation. |
