Advanced Process Control - Cooling System at Brewery

Customer: AMBEV

Location: Several factories around Brazil.

Challenge: Stabilize the temperature of the coolant that will be used by cold consumers in the manufacturing process, as well as avoid the persistent accelerations and decelerations observed in the compressors.

Solution: The OptProcess© software has been deployed together with a Model Predictive Control (MPC) controller. In this type of control, the future trajectory for the (controlled) process outputs is predicted using a process model and the past variations of the process inputs (manipulated and disturbances). This prediction calculates the best combination of control actions in the manipulated so that the subsidiaries follow a reference value.

Result: Reduction of 3% to 5% in energy consumption and up to 40% reduction in temperature variability from the coolant to the process.
