Verfahren zur Unterdrückung der Bildung von Schwefelsäureaerosolen in Abgasreinigungsanlagen

摘要

Disclosed is a method for preventiong the formation of sulfuric acid aerosols in flue gaz cleaning plants, whereby said flue gas are preimpregnated with water before the sulfuric acid contained in the flue gas passes below the dewpoint, that preimpregnation being carried out upstream of the gas purifier, upstream of the prewasher installed in addition to the clean purifier, or upstream of a heat exchanger mounted upstream of the washer, and in such a way that the gazeous sulfuric acid is absorbed by water prior to passing below the dewpoint.
