Optimization of Technological Parameters of Complex Chlorinating Ash Processing Technology

Abstract

Today, the problem of ash processing is not in the absence of rational technology, but in solving the problem of complex extraction of valuable components (metals) from it. A new method has been developed for calculating and optimizing the technological parameters of key processes of magnetic separation of ash, chlorinating firing of non-magnetic fraction and leaching of the stub with hydrochloric acid (30%) to obtain pure silica. Based on new approaches and solutions using the latest achievements of IT technologies, models have been developed that allow predicting the outputs of the products of the main processes depending on the initial parameters and the consumption of the reagents used. For ease of use in practice, nomograms have been constructed using mathematical models that allow determining the final technological parameters of processes depending on various parameters (productivity, iron content, reagent consumption, etc.) without complex technological calculations. Nomograms are the necessary tools for the selection and justification of the main and auxiliary equipment of the integrated ash processing technology developed by the authors of this work.
