Abstract

Abstract: This article introduces the main types and mechanisms of corrosion in atmospheric and vacuum distillation units as well as the design intention and operation requirements of anti-corrosion measures such as ‘one removal and four injections’ in the No.4 atmospheric and vacuum distillation unit in Zhenhai Refinery. The analysis of the main properties of raw materials during the initial operation of unit, the actual operating conditions and the corrosion monitoring results show that various process anti-corrosion measures are implemented smoothly and effectively, and the corrosion indicators are normal in general, meeting the production requirements.
