Sulzer Agitator Case Study for Ferric Chloride Production

This case study outlines the challenges faced by a leading Spanish chemical manufacturer in the production of ferric chloride due to persistent agitator failures. The document details the previous attempts to resolve these issues through various agitator configurations, which ultimately failed to provide the necessary reliability against the corrosive nature of the ferric chloride solution. Sulzer's engineered solution involved the implementation of a SALOMIX™ vertical agitator, designed with all wetted parts made from grade 2 titanium, known for its exceptional corrosion resistance. The case study presents the specifications of the new agitator, including its motor, gearbox, and impeller design, which collectively enhance operational efficiency and reliability. Since the installation of the Sulzer agitator, the customer has experienced continuous operation without failures, demonstrating the effectiveness of the tailored solution in addressing the demanding conditions of ferric chloride production.
