Abstract
The results of the study on the development of a system of models of interconnected reactors of the sulfur production unit of the Atyrau Refinery are presented. The development of models of complex technological systems such as the sulfur production unit is complicated by their complexity and uncertainty associated with the shortage and ambiguity of the initial information. In this regard, the goal of the study was defined as the creation of a package of models of interconnected units of complex technological systems with a deficit and ambiguity of initial information based on available information of various natures. The main results of the study are: a method for creating a system of models of interconnected units of complex chemical-technological systems characterized by a deficit and fuzzy initial information; system analysis, expert assessment of various types of models and selection of an effective model of the main units of the studied sulfur production unit; hybrid models of a thermal reactor, Claus reactors and Cold Bed Absorption were developed based on available statistical data obtained by passive, active experiments and fuzzy information received from the decision maker and experts; a scheme for combining models of reactors and condensers of the sulfur production unit into a single package of models was proposed, according to which a package for system modeling and optimization of the operating modes of this unit was created. The scientific importance of the obtained results lies in the development of methods for developing mathematical models and system modeling of complex technological systems under uncertainty. The practical significance of the work is that the proposed method can be used to develop a package of models of various technological systems and systematically model their operating modes to optimize their parameters.
