Problem of disposal of organochlorine waste of vinyl chloride production

Abstract

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. It is established that the use of oxalic and hydrochloric acids as extractants significantly reduces the iron content in the stillage residues of the rectification column, which allows increasing the duration of operation of the organochlorine waste incineration equipment.
