Abstract (en)
[origin: WO2005031008A1] Disclosed is a method for granulating slag, especially from a blast furnace and/or a smelting reduction system. According to said method, a mixture of granulate and water obtained during the granulation process is delivered to a granulating container (4) and then to a dehydration system in which the granular slag is dehydrated while the vapors and gases that are created during the granulation process and contain H2S are at least partly condensed in a condensing chamber which is fluidically connected to the granulating container (4) by spraying water thereinto. Residual gases containing H2S are withdrawn from the condensing chamber below the point where water is sprayed in, and H2S is burned.
