Models about chemical processes and plants contain valuable knowledge about the companies assets. Considering the costly efforts needed for their development, it must be considered a waste of resources that (in general) models are neither reused for the development of new models and often not even used for simulation studies in late activities during plant design. This is mainly caused by (i) insufficient means to distribute, maintain, and communicate models within the process design team, and (ii) a lack of integration among process modeling and simulation tools that would enable the combined use of existing models for a simulation independent of the tool they have been developed with. This contribution presents an open environment that aims at the management of chemical process models over the lifecycle of the process design activity. The environment comprises a repository for the storage of heterogeneous models in a tool independent format, a modeling tool for the development and administration of models in the repository, a model integration platform for simulation which can execute simulation experiments involving otherwise incompatible tools and a thermodynamics server ensuring consistent physical property calculations for all models involved. Results are presented along the development of a Nylon production process as a case study.
