Paranyak N. Improvement of methods to reduce the technogenic impact on the environment of dust emissions in cement production.

The object of the research is the process of environmental pollution caused by dust emissions while cement production. The subject of the study is the reduction of anthropogenic impact on the environment because of dust emissions. Research methods are based on the methods of mathematical analysis and modelling, as well as the fundamentals of aerodynamics and theoretical mechanics. The following techniques were used to define the morphometric and physicochemical properties of the aerosol: the hydrodynamic technique (to determine the air flow, velocity, and pressure changes), the weight technique (to determine the purification efficiency), sedimentation (to determine the disperse composition of the dust), and the methods for determining the aerosol density, viscosity and specific surface. Theoretical calculations and experimental data processing were performed using the computer program Microsoft Excel, EOL 2000, SolidWorks, and FlowVision. The basic methods of mathematical statistics and mathematical calculations of error deviation were used to process the results of experimental studies. EOL+ programme was used to calculate the dispersion of harmful components in the environment. Statistical analysis of the research results is carried out with the regression analysis using software packages. The degree of implementation: Tests have been conducted for the introduction at Ivano-Frankivskcement JSC. The research results are to be applied to cement industry enterprises.
