Presentation Sumary: The economics and energy and resource efficiency of chemical production processes can be significantly improved by employing model-based optimizing control and model-based real-time optimization. We will discuss new developments in this area, focusing on how to cope with the inevitable deficiencies of model and the optimization of large production sites by distributed optimization and coordination.

We will first discuss the real-time optimization of the operating points of processing plants using a combination of models and measured data that was obtained at previous operating points. The measured data is used to iteratively correct the optimization model by means of the so-called modifier adaptation principle. In this context, we propose a novel way of estimating the modifiers – the empirical plant gradients- which is based on ideas from derivative-free optimization: MAWQA – Modifier Adaptation with Quadratic Approximation.

Secondly, we discuss the advantage of economics optimizing model predictive control and introduce multi-stage optimizing control which is a systematic way to achieve optimal performance and robust constraint satisfaction in the presence of model uncertainties. In contrast to other approaches, the presence of feedback in the control loop which enables corrections of the predicted control moves after new information has been obtained is taken into account in the optimization by computing so-called recourse actions.

Finally, for a number of reasons in large production sites an integrated optimization of the overall site is not feasible. We propose to use distributed optimization and coordination by market-like mechanisms and explain the principle by means of a case study of a Petrochemical plant.
