Abstract
1. Способ извлечения хлора из отходов производства хлора и винилхлорида, включающий процессы сжигания хлорорганических отходов и получения хлора методом электролиза, отличающийся тем, что соляная кислота от установки сжигания отходов без дополнительной очистки от хлора и других примесей смешивается в реакционном сосуде с потоком или частью потока анолита от установки электролиза, содержащим отход электролиза - хлорат натрия в количестве 0.5-10 г/дм, при температуре 92-106°С и поддержании концентрации соляной кислоты в реакционной массе 10-20 г/дм, обеспечивающим исключение образования диоксида хлора и уменьшение времени разрушения хлората натрия с образованием хлорида натрия и молекулярного хлора, который возвращается в производственный процесс на стадию синтеза 1,2-дихлорэтана, промежуточного продукта в производстве винилхлорида.2. Способ по п.1, отличающийся тем, что время пребывания реакционной массы в реакционном сосуде составляет 25-30 мин.1. A method of extracting chlorine from waste products of chlorine and vinyl chloride production, including the processes of burning organochlorine waste and producing chlorine by electrolysis, characterized in that hydrochloric acid from the waste incinerator without additional purification from chlorine and other impurities is mixed in the reaction vessel with a stream or part of a stream anolyte from an electrolysis unit containing electrolysis waste - sodium chlorate in an amount of 0.5-10 g / dm, at a temperature of 92-106 ° C and maintaining the concentration of hydrochloric acid in the reaction mass of 10-20 g / dm, ensuring the exclusion of the formation of chlorine dioxide and a decrease in the time of destruction of sodium chlorate with the formation of sodium chloride and molecular chlorine, which is returned to the production process at the stage of synthesis of 1,2-dichloroethane, an intermediate in the production of vinyl chloride. 2. The method according to claim 1, characterized in that the residence time of the reaction mass in the reaction vessel is 25-30 minutes
