Development of a model system for the technological complex of benzene production

   Mathematical models of aggregates of complex technological complexes and problems of constructing a system model of a complex, i.e. a structured model, are studied, an approach to constructing a system of models of a technological complex based on various information based on the methodology of system analysis is formulated. A clear production system
has been built – mathematical models of rectification and benzene columns of the main units of the benzene complex. In the work it is established that according to the proposed approach it is advisable to build composite models on these aggregates, i.e. the number of products at their output (benzene, raffinate, heavy aromatics) is determined by constructing aggregate regression models, and product quality indicators are fuzzy. The influence of aromatic hydrocarbons contained in the reformate on the average octane number of benzene is the main indicator of product quality, constructed in the form of a linguistic model based on a logical rule of conditional generalization and a knowledge base.
