Abstract
Методът намира приложение във всички области на промишлеността, където се използват топилни пещи, отделящи отпадъчни газове, съдържащи sо2 и sо3, по-специално топилни пещи за производство на стъкло, например натриево-калциево. С него се повишава степента на очистване на отделяните газове от серни съединения. По време на охлаждането на отпадъчните газове се създават условия за окисляване на sо2 и sо3 чрез използване на охлаждащо средство, съдържащо натриев хидроокис, натриев сулфат или калциев хидроокис. При филтрирането sо3 се абсорбира от слоя натриев сулфат върху филтъра. 11 претенции
