The presentation will give an overview of how process modeling and simulation is applied at Bayer. The Bayer group with its three core businesses Materials Science, Crop Science and Health Care has a large variety of plant operations. There are plants with capacities larger than 200 000 t/year producing commodity type of products. Other plants based on biological processes produce very small amounts of high value products under GMP conditions. Sewage treatment plants clean large amounts of a combination of municipal and industrial waste waters. Obviously, these plants operate in different environments and are driven by different business and technical factors. This determines the kind of problems where process modeling is applied and also how it is applied. In particular the level of detail in a process model strongly depends on the nature of the problem to be solved. Some models require details like particle size distributions or fermentation kinetics e.g. for the development and optimization of feeding strategies. The generation of consistent mass and energy balances as a basis for the workflow of plant and equipment design requires the coverage of all process and utility streams in a single model. It is a challenge to integrate such different scales of modeling and ensure information consistency in the models. This challenge can be approached with the idea of Lifecycle Modeling, where a common modeling approach is applied to support process development, plant engineering, optimization of plant operation and debottlenecking projects. The tools and methods as well as the workflow that are used in industry will be described in the presentation. We will also give an assessment from our perspective on current issues. The focus of the presentation will be on examples and applications to illustrate the different approaches and scales of modeling that are applied.
