Sulzer’s automated welding delivers quality and cost-efficient corrosion protection for distillation columns. The efficient prevention and minimization of corrosion-induced deterioration in distillation columns is a key aspect of helping refineries to remain highly productive and competitive. Sulzer’s automated weld overlay capabilities provided an economical and efficient solution to debottleneck the different columns and extend their service lives.
The refinery complex is one of the five largest in Spain. The plant processes crude oil to obtain a broad range of chemicals, such as methyl methacrylate and polypropylene. When the refinery noticed extensive corrosion within the column shells of three main separation towers, it sought to investigate the issue and protect its plant from costly shutdowns or lengthy periods of suspended production.
Sulzer offered a third, more time-efficient, economical and long-lasting option: weld overlay. By using this in situ process, it is possible to cover large column surfaces with corrosion-resistant alloys. The company is highly experienced in this technique and has developed a state-of-the-art, fully automated weld overlay equipment to support its operations.
