Modeling of technological installations of resource saving chemical-technological processes based on object-oriented approach

The possibility of using an object-oriented approach to the creation of information systems of modeling and design of complex chemical-technological processes are considered. Building information models of technological processes using the object-oriented approach involves several stages: the construction of the domain model, the creation of the model of system activity, the formation of an information model and the creation of database models of technological process. As a result of an iterative process, with incremental build-up opportunities, object-oriented design model of chemical-technological system was elaborated; it is to be subject to further code generation. The proposed scheme of designing information models of chemical and technological systems has been used in the development of computer environment for modeling and design of processes of thin organic synthesis — diazotization and azo coupling. Built in the system information models of diazotization and azo coupling allow to calculate not only the parameters of the state of chemical-engineering processes, but also to determine their quality indicators. The results of the calculation of quality indicators of azo pigment were shown as an example. Computational experiments, modeling of technological processes of synthesis of azo pigments, study their static modes, construction areas of permitted functioning modes of the reactor azo coupling system allow to come to the the conclusion about the necessity of formulating and solving problems on optimization of technological modes of process of synthesis of the azo pigments. This will not only improve the quality of the azo pigment, but also receive azo pigment with specified quality and physical and coloristic indicators.
