An object-oriented approach to modeling chemical processes with control systems in the modeling language Omola is discussed. The basic elements in this modeling methodology are modularization, model encapsulation, hierarchical decomposition, parameterization and inheritance. Models have an internal structure of model components, like terminals, parameters and behavior descriptions. The model behavior can be described by equations or as a connected structure of submodels. Models and model components are represented as objects in single inheritance object class hierarchies. Chemical processes and control systems can be described with the same basic concepts. The object-oriented model representation is implemented in the Omola simulation environment, called OmSim. An exothermic tank reactor example is successfully modeled and simulated
