| Abstract: | This paper analyzed the causes of pipeline corrosion at the injection point of the slurry antifoulant in catalytic cracking(FCC)units and modified its injection point location.Four years operation after transformation,the corrosion reduction and thinning of pipeline near the injection point of slurry antifoulant was less than 1 mm,the remaining thickness was more than 7 mm,which effectively solved the pipeline corrosion around the slurry injection point and ensured the safe and long lead operation of the unit. |

| Keywords: | catalytic cracking slurry antifoulant corrosion reduction and thinning long lead operation |
