РЕКУПЕРАЦИЯ НЕФТЕСОДЕРЖАЩИХ ПРОМЫШЛЕННЫХ ОТХОДОВ КАК ФАКТОР СНИЖЕНИЯ УГРОЗ ТЕХНОСФЕРНОЙ ОПАСНОСТИ

Abstract

The relevance of the study is predetermined by the unresolved problems of disposal of oil-containing waste in the Yaroslavl region. The purpose of the study was to analyze the system for preventing technospheric hazards caused by the formation of industrial waste and their negative impact on the environment. The object of the study was industrial waste, highly hazardous to the environment, characteristic of a number of enterprises in the region: acid tar. The subject of the study was the process of optimizing the composition of a bitumen binder based on acid tar in terms of the content of galvanic sludge, captax and sulfur for subsequent use in a modified form as a secondary oil-containing raw material for the production of bitumen emulsions, pastes, and lubricants. Such raw materials, technologically brought to a low-hazard level, can be successfully and effectively used in various production operations of construction, reconstruction, operation, and repair of facilities. The optimization process was carried out using statistical research methods using, during modeling, the obtained dependence of the withdrawal properties on the factors of a second-degree polynomial with two unknowns. Calculations were performed using an Excel spreadsheet package with built-in mathematical local calculation programs. The research results in the technological part have been patented and implemented in the practical activities of enterprises in the region. The value of scientific and practical developments lies in reducing the volume of formation and storage of hazardous oil-containing acid tar waste and, as a consequence, preventing and reducing the level of technospheric danger and potential man-made emergency situations.
