| Abstract: | Through the investigation on the corrosion situation at the dead and cold zone of the debu- tanizer tower, flash -steaming tank, T-103 tower and piping system in the post-processing of poly-isobutyl- ene unit, we find the main corrosion reason of these parts is A1C13 hydrolysis, chlorinated polyisobutylene py- rolysis and sulfur corrosion. So we put forward the suggestion about the protective measures in the current process and improvement on the process conditions and equipment material. |
