Claims (1)

  1. Изобретение относится к способу получения двуокиси хлора, при котором снабжают реактор водной кислой реакционной средой, содержащей хлорат и сульфат щелочного металла, причем концентрация сульфата превышает примерно 3 моль/л, но меньше, чем насыщение; восстанавливают ионы хлора в реакционной среде для образования двуокиси хлора; удаляют газ - двуокись хлора - из реакционной среды; удаляют реакционную среду из реактора и передают ее в электролизер; электролизуют реакционную среду для увеличения кислотности и уменьшают содержание ионов щелочного металла; подкисленную рециркуляционную среду рециклизуют в реактор; добавляют подпитывающий хлорат щелочного металла в реакционную среду до или после электролизера; причем способ осуществляют по существу без кристаллизации сульфата или хлората.
