Conference: Galveston 2020

Crude mix within the distillation column evolved and now included more naphthenic acid. Due to this change in operating conditions, corrosion on the top and bottom of the column was anticipated. Inspection revealed this corrosion to be more severe. The available time on the critical path was optimized to clad the largest possible area, preventing future loss of integrity.
