Abstract

Purpose: prevention of complications in compliance with the occupational hygiene of workers of industrial enterprises and reduction of the harmful effects of industrial flue gases on the inhabitants of the adjacent territories thanks to the graphic presentation, systematization and analysis of the influence of technological parameters on the indicators of desulfurization of gaseous emissions.

Approach: analytical method and mathematical modeling were used as the main research methods.

Findings: thanks to industrial data, double dependences of the degree of desulfurization of flue gases on the temperature conditions of the process, the volume of gas entering for cleaning, and the volume of gas entering for recirculation are graphically expressed. Corresponding linear mathematical models were built. This makes it possible to optimize technological indicators with further regulation of the desulfurization process to increase its efficiency. Achieving a reduction in the pollution of flue gases by sulfur dioxide contributes to the prevention of complications in the observance of occupational hygiene of workers of metallurgical enterprises, to the reduction of harmful effects on the health of the population of the regions close to the production area.

Practical implications: on the basis of industrial data, double dependences are determined, which allows to achieve certain values of the degree of desulfurization of flue gases when adjusting the technological parameters of desulfurization with the establishment of the most rational indicators. The obtained results can be used in the optimization of the production process of industrial enterprises, the activity of which is accompanied by gaseous emissions with sulfur content.

Value: mathematical models of double dependences of the degree of desulfurization on the technological parameters of the flue gas filtration process in industrial conditions were built. The obtained results are presented in the form of equations. For greater visibility, double graphs were constructed with the plotting of points of industrial indicators and the line of the obtained model.

Future research: the development of future research is possible in the direction of optimization of the constructed mathematical model.

Paper type: calculation-practical and analytical.

Keywords: desulfurization, mathematical modeling, safety, work.
