Abstract
In the production of ammonium sulphate by passing into a saturator gases which are liable to contain cyanogen compounds, the cyanogen compounds are prevented from reaching the saturator by adding to the ammoniacal liquor to be distilled a polysulphide, or forming a polysulphide in the liquor, for instance by adding sulphur or blowing in air, so as to fix the cyanogen compounds in the liquor as sulphocyanides; or the vapour from the still may be passed over spent oxide on its way to the saturator. In the case of the direct process, the ammoniacal gas is passed through a washer containing a polysulphide solution. Specifications 845/71, 16172/12, and 29047/13 are referred to.
