Advanced process control for Prime-G™

APC uses a model-based predictive control technology that drives the process towards the desired targets through the manipulation of several variables simultaneously while observing all process constraints. APC has a proven track record in delivering business objectives: reducing energy costs, increasing yields and improving operability.

Axens’ Performance Programs Business Unit provides S², our State Space APC suite, designed to efficiently implement and maintain plant-wide APC applications. The benefits of these applications have been fully demonstrated on several plants.
