The application of the process modelling tool ProMoT to large-scale chemical engineering processes is presented. Particular emphasis is on the flexibility of the tool in terms of creating flowsheet alternatives-a prerequisite for efficient plant design and control structure selection. The main concepts in this respect are the bottom-up development of an object-oriented knowledge base for the simplified implementation of submodels on the level of process units, the efficient aggregation on the flowsheet level and the flexibility to effectively perform topdown refinements for problem-specific applications. All concepts are illustrated on the basis of an industrial scale process.

Computer tools can support and accelerate the development and implementation of first-principle models for chemical and biological processes significantly. Several application examples illustrate this in the contribution. Models of a biochemical reaction network, of a catalytic fixed bed reactor, and of two chemical production processes are considered. The models are implemented in a structured way in the process modeling tool PROMOT, whose key features are discussed. The structuring of the models is based on a uniform structuring methodology whose main ideas are presented as well.
