Investigation of industrial contamination of protective clothing at oil industry sector

The article presents the research results of the interaction of the protective clothes surface with polluting components of production facilities of the oil and oil refining industry. The development direction of an oil-resistant clothing segment is proved. The aggressive components of the production environment of the oil sector are substantiated with respect to the protective functions of special clothes. Oil and petroleum products lead to a change in the properties of textile materials. This depends on the concentration of aggressive components in the structure of textile materials. The research results of the interaction of petroleum products with a textile composition of a woven structure with protective properties are presented. Based on the study of 50 suits that have passed the operational cycle of one season, restrictions are established on the areas of the clothing surface of uneven protection. Clothing zones risk-affected loss of protective effect is established. The results of experimental studies of the concentration of petroleum products in textile materials after chemical purification based on the method of gas capillary chromatography are presented. It was found that the main component with a high concentration of pollutants is hydrocarbons from C14H30 Tetradecane to C36H74 Hexatriacontane. The average values of the concentration of hydrocarbons on the purified samples for the main parts of the clothing surface were established. Using the methods of acoustic emission, the experimental level of contact activity of the permeability of the liquid phase of crude oil in the structure of woven textiles at the boundary of media is established. The effect of the saturation of protective clothing by the petroleum fractions on its strength has been experimentally evaluated. The chemical compositions of the active phases were identified on the basis of experimental data. This is the contact materials of industrial pollution at oil refining facilities. Recommendations have been developed to improve the system of individual protection of man during interaction with a polluting environment taking into account chemically aggressive components.
