Spartan’s solutions are tailored to meet challenges in this demanding environment and allow effective operation of the recausticizing. Highly accurate Rosemount instruments are used to measure key process variables including flow, temperature, density, and conductivity. Fisher control valves are used to control flow while minimizing the effect of scaling and erosion. The predictive modeling and advanced tuning functionalities in DeltaV allow operators to control and optimize the process by maximizing causticizing efficiency while maintaining consistent white liquor quality.
