Emissions of industrial enterprises in their structure are mostly aerodisperse systems, in which the dispersed phase is organic and inorganic dust or fine droplets, and the dispersion phase is a gas-air mixture. This mixture may comprise several contaminating gaseous components. In many cases, the components of the exhaust gases have an additive effect or are capable of transforming into more dangerous compounds, which in the conditions of background concentrations characteristic of most industrialized areas makes them dangerous even at relatively low concentrations in emissions.

The sources of organochlorine waste formation, its toxicity, and environmental impact are analyzed, and methods of its disposal are considered. The composition of insoluble compounds in the stillage residues of the dichloroethane rectification stage before incineration is determined, and the method of their extraction is proposed.

The actual problem of acid sludge utilization which is the wasted products of oil-refining industry is examined. The neutralization method of acid sludge in order to neutralize sulfonic acids and excess of sulphuric acid is studied. The results of the oxidation process study of neutralized acid sludge and its joint oxidation with oil tar are given. The possibility of acid sludge application for the bitumen production is established.  Розглянуто актуальну проблему утилізації кислих гудронів, які є відходами нафтопереробної промисловості.
