FIELD: separation of mercury from gases, particularly, continuous and simultaneous collection and precipitation of mercury from mercury-containing gases. SUBSTANCE: method includes passing of mercury-containing gas through washing tower to which hydrogen sulfate is injected continuously, or periodically at moment of time coinciding with washing by solution containing complex of mercury (II), for instance, [I<SB>4</SB>Hg] or [(SCN)<SB>4</SB>Hg] , not needing of additional oxidizer. Collection and precipitation of mercury and regeneration of solution containing complex of mercury (II) are carried out simultaneously and in one stage only. EFFECT: simplified process and reduced working costs. 7 cl |
