The hydrocyanic acid gas, together with the nitric oxide, is passed through alkali, whereby all the HCN is absorbed as alkaline cyanide, and is recovered by evaporating. The nitric oxide passes forward, mixed with air, through towers... 

Practically all the ferrocyanide of to-day is recovered from coal gas. 100 kg. of coal yield on destructive distillation some 30-40 g. of hydrocyanic acid gas, HCN. In 100 volumes of unpurified coal gas there are o.1-0.2 per cent, by volume of HCN gas. In general, of the 1-2 per cent. N found in coal, some 15 per cent, is converted into NH3, 2J per cent, as HCN, and 48 per cent, remains behind in the coke. The rest of the N escapes as such. The exact amount of HCN produced depends upon many factors, such as the moisture in the coal (which acts unfavourably), the rapidity and length of heating, etc. Rapid heating and a high temperature favours the formation of HCN,...
