Generalized Model for Engineering and Controlling a Complex Multistage Chemical Energotechnological System for Processing Apatite-Nepheline Ore Wastes

Resumo

A comprehensive formulation for the problem of engineering applied to a multistage chemical energotechnological system for the production of phosphorus from the technogenic wastes of apatite-nepheline ores is presented. The main objective of the studies performed within the procedure of engineering is to determine the phosphorus-production technology parameters decreasing energy and resource efficiency due to the optimization of energy-consumption values for all considered multistage chemical energotechnological processes instead of individual stages. A generalized model of engineering is developed for the chemical energotechnological system of phosphorus production in compliance with the IDEF0 International Standard of Function Modeling, and parameters suitable for further use in the procedure of minimizing the energy and resource efficiency of this production are concretized for multistage chemical energotechnological processes. A conceptual foundation based on the methods of automatic control theory, i.e., the state-space description of control objects, is proposed for the creation of a universal program-optimization model for a chemical energotechnological system. Some results of a simulation experiment in the Simulink environment for the modeling of dynamic systems are presented to demonstrate the applicability of the proposed approaches to the optimization of multistage chemical energotechnological processes.
