Abstract

Изобретение относится к способу получения тиосульфата калия, сульфита калия или бисульфита калия, включающему следующие стадии. Стадия (1a): получение раствора гидроксида калия или карбоната калия для нейтрализации кислотообразующих компонентов, таких как растворенный SOили HS; стадия (1b): получение раствора, контактирующего с SO, содержащего по меньшей мере некоторое количество сульфита калия, или бисульфита калия, или тиосульфата калия; стадия (2): получение газообразной двуокиси серы; стадия (3): осуществление взаимодействия этих веществ для абсорбирования газообразной SOи образования промежуточной реакционной смеси, включающей сульфит калия, или бисульфит калия, или их смесь, и, при необходимости, извлечение сульфита калия, или бисульфита калия, или их смеси, и/или, возможно, с использованием стадий 4 и 5; стадия (4): добавление в реакционную смесь серы или сульфидсодержащего соединения, содержащего серу, имеющую степень окисления 0, -2 или между 0 и -2, и, возможно, гидроксида калия или карбоната калия, и осуществление взаимодействия этой смеси в подходящих условиях с образованием тиосульфата калия; и стадия (5): извлечение тиосульфата калия и, возможно, концентрирование тиосульфата калия.
