Abstract

PURPOSE: To prevent the lowering of SOx and NO removing rate in absorbing liquid liquid, by regulating pH of absorbing liquid between the lower part of absorbing tower and oxidizing tower and converting nitrogen compounds, generated in absorbabsorbing liquid, to amine group nitrogen compounds and moreover, decomposing to harmless nitrogen.
