Prevention of occupational risks of the harmful effects of sulfur dioxide on the health of workers and the development of environmental safety during the purification of industrial gases
Abstract
Purpose: prevention of occupational risks and reduction of harmful effects on the health of workers of industrial flue gases, together with improvement of environmental safety thanks to mathematical modeling regarding the optimization of technological indicators of desulfurization at metallurgical enterprises.
Approach: regression analysis was used as the main research method.
Findings: the multifactorial mathematical model of the dependence of the degree of desulfurization on the technological parameters of the flue gas filtration process at the metallurgical enterprise was built on the basis of industrial data. This makes it possible to optimize technological indicators with further regulation of the desulfurization process to increase its efficiency. Achieving a reduction in flue gas pollution with sulfur dioxide contributes to the prevention of occupational risks and the reduction of harmful effects on the health of employees, as well as to the improvement of the level of environmental safety.
Practical implications: the dependence on the basis of industrial data was determined, which allows adjusting the value of the degree of desulfurization of flue gases when changing the technological parameters of filtration with the establishment of the most rational indicators. The obtained results can be taken into account in the adjustment of the production process of both the metallurgical industry and other industrial enterprises, for example, thermal power plants.
Value: the mathematical model of the dependence of the degree of desulfurization on the technological parameters of the flue gas filtration process in industrial conditions was built. The obtained results are presented in the form of a multivariate regression equation. For greater visibility, based on the obtained dependence, three-dimensional graphs are constructed and graphically shown in accordance with some of the considered technological parameters.
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.
