Abstract
MODELING OF THERMODYNAMIC PROCESS IN SILICATE TECHNOLOGIES Solodka N.O., Sigunov O.O., Aleksyeyev D.A. Abstract The study of new processes of chemical technology is impossible without a prior thermodynamic analysis and calculation. Timeliness is that the experimental definition of thermodynamic characteristics is complicated and the accumulate of reference data on the thermodynamic properties of substances lags behind consumer inquiries. The possibility of calculating thermodynamic functions using empirical methods is of interest. It is advisable to carry out the above-mentioned tasks with the use of computer technology, because it will allow thermodynamic calculation without the high costs of time and resources. The aim of the work is to improve the quality and automation of the thermodynamic study, to calculate the dependence of Gibbs energy on the temperature. It is achieved due to the program design and implementation of the mathematical model of thermodynamic calculation in silicate technology. To achieve this goal, the following tasks have been completed: designing an information subsystem for modeling the thermodynamic process in silicate technology; implementation of the algorithm for calculating the dependence of Gibbs energy on the temperature series; development of software for calculating the dependence of Gibbs energy on temperature; development of an easy-to-use and intuitive interface for the user; creation and filling of data base of chemical substances and their thermodynamic properties; enforcement of the decision in numerical and graphical form. In the proposed information subsystem, simulation of the thermodynamic process in silicate technology was carried out by the algorithm for calculating the depend of the Gibbs energy change on the temperature indicator. In the future, further research is a refinement of the subsystem on the side of supplementing the classes of chemical reactions by increasing the number of input and output agent that take part in the reaction. It is necessary to offer the possibility of editing the database of chemical elements and their thermodynamic properties, given the constant increase in the number of chemicals in the technology of silicates. The obtained results can be used for carrying out thermodynamic calculations, as well as in the educational process during laboratory lessons from disciplines where thermodynamic studies are used.
