Thermal Oxidizer Optimization
Two Model Predictive Controllers were implemented on a Thermal Oxidizer at Ascend Performance Materials using DeltaVâs MPCPro block. These controllers allowed Ascend to optimize firing rates, combustion air usage and heat recovery while maintaining environmental compliance. This made it possible to reduce fuel consumption by more than 10% relative to baseline operation. Prior to MPC implementation, operating conditions for the WHB, including temperatures, excess O2, and combustion air preheat, were manually set by Operations personnel. This often resulted in boiler firing rates that were much higher than necessary to maintain permit limits for carbon monoxide (CO) emissions.
