Chemical Technology, Control and Management


Considers a systematic approach to mathematical modeling of a complex, multistage carbonization process, which allows for taking into account the stoichiometric dependencies of the ongoing reactions. A kinetic model of the carbonization process based on chemical reactions in the carbonation column is proposed, which is the basis for obtaining the functional dependence in the form of a mathematical model of the main indicator of process quality-the degree of sodium utilization from the outlet streams of the carbonation column. The proposed systematic approach to the development of mathematical models based on stoichiometric ratios and the coefficients of reversibility of the ongoing reactions makes it possible to develop control systems for quality indicators for chemical processes and to justify the rationality of the model structure for the purposes of operational control of objects of chemical processes with reversible reactions.
