Abstract

Cyanogen compounds are removed from coal gas as calcium ferrocyanide by treating the gas in a lime purifier to remove sulphuretted hydrogen and carbonic acid, and then in the same purifier treating with slaked lime impregnated with a solution of a salt of iron such as ferrous sulphate. The ferrous sulphate may be added to the lime in a tier of the lime purifier near the exit, and when the purifier is spent the material from this tier is leached or agitated with a dilute alkali to obtain alkali ferrocyanide.
