Acid tars: environmental problem or secondary resources?

The study analyzes the most important areas of processing acid tars, a specific type of non-permanent composition waste, the main source of which are the processes of oil refining and storage. Among the complex of substances included in the composition of acid tars are very aggressive components of high hazard classes, which creates risks of secondary pollution of natural environments when the storage tank is overflowing or loses its integrity. Despite more than 100 years of development history, sufficiently effective technologies for their processing have not been proposed to date. For Russia, the problem is very relevant: several storage facilities for this type of waste are included in the register of objects of accumulated environmental damage and are subject to prompt environmental rehabilitation. As a solution to the problem, it is proposed to apply an approach consistent with the principles of green economy: neutralization of acid tars using waste from other industries, such as the food industry or agriculture. The result of neutralization is a decrease in the degree of hazard of waste for the environment, “mutual neutralization” of waste of various origins and the prospect of obtaining material suitable for economic use. In addition to the actual technological solution for waste neutralization, it is proposed to systematize information on existing technologies in this area - to create an information and reference system. Which will allow organizing information on developments and will facilitate the selection of optimal solutions for each storage facility, taking into account the individual characteristics of the stored waste and the availability of technological solutions from the standpoint of the best available technologies (economic, environmental, technological availability and efficiency).
