Object-oriented modelling of large-scale chemical engineering processes with ProMoT

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 top-down refinements for problem-specific applications. All concepts are illustrated on the basis of an industrial scale process.
