We focus on development of new methodology and tools for process control in order to obtain high product quality and yield, combined with well controlled operation in regard of the health, safety and environmental requirements. The benefits from optimal control will show up directly at the bottom line.
The relation between process design parameters and plant operability are not generally known for new emerging process technologies, thus analysis of the dynamic and operational properties are important.
More compact process designs tighten the operational margins and require higher attention on process control for disturbance rejection and handling of interactions. We contribute in the development of good and practical solutions. It spans from basic regulatory control for single units and small dedicated plants, even micro systems, up to complex integrated plants like oil and gas processing systems that operates in a dynamic market. The solutions involve man, technology and organisation issues.
