FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy field, particularly to beading of blast-furnace slag and/or slag from the melting-reducing unit. Metjod includes feeding of formed during the beading mixture of granulated material and water into the tank for granulation. Then mixture is fed to the facility fir dewatering for water separation from granulated material. Escaping during the beading gas and steam, containing H2S at least partially condensed by means of water dispersion facility in condensation chamber. Residual gas, containing H2S, is discharged from chamber lower the water dispersion facility and H2S is burnt. There are proposed versions of facility for methodimplementation.
EFFECT: reliable reduction of concentration H2S in escaping during the beading gas and steam up to permissible limits.
