During organochlorine wastes thermal utilization formed at direct chlorination of ethylene to 1,2-dichloroethane in the production of vinyl chloride at Karpatnaftohim LLC, the ash is formed, which clogs gas pipelines and heat exchange elements of the steam generator, causes disruption of normal technological process and leads to emergency shutdowns.The composition of this ash was determined by chemical methods of quantitative analysis and flame photometry for such macrocomponents as Fe2O3 (28%) and FeCl3 (5%), as well as magnesium chlorides (30%) and sodium (4%), the rest (about 32% ) probably resinous highly chlorinated unburned components of VAT residues, carbon particles and nitric acid-insoluble iron compounds. Utilization methods and possible ways to reduce the amount of ash from the organochlorine waste combustion formed at the production of vinyl chloride are briefly considered.
