Measures to Prolong Operating Period of Atmospheric Vacuum Distillation Unit

Aimed at the problems of the crude oil having complicated properties and containing higher corrosive media, such as sulfur and acids, this paper optimized the design, e.g., selecting corrosion resistant alloy material, strengthening process anti-corrosion and improve equipment administration level, etc., to greatly prolong the operating period of the atmospheric vacuum distillation unit. The overhaul cycle of the unit was shortened from the original once a year to the present once 2 years, and the economic benefits were also improved.
