Abstract
Sulphur is manufactured out of sulphur dioxide containing gases by dividing the feed gas in two flows of gas having a volume ratio of 2 to 1 and reducing the greater flow of gas on a carbon containing substance like anthracite, thereby obtaining hydrogen sulfide which is mixed with the smaller flow of gas, the mixture being converted in a Claus process to sulphur.
