2023 Tien PVCFC Corrosion in water seal drum of flare system
This paper focuses on the components of a typical flare system, including the knockout drum, seal drum, and flare itself. It highlights the critical role of a properly operating flare system in preventing plant disruptions from turning into disasters.
A case study of erosion-corrosion damage found in the water seal drum of a flare system after 4.5 years of operation is presented. The causes of the damage, including the corrosive element CO2/H2CO3, are analyzed, and a repair solution involving the upgrade to 304L stainless steel is proposed. The success of the repair is confirmed through five years of subsequent operation.
