In the manufacture of sulphur from hydrogen sulphide by burning a portion thereof to sulphur dioxide and reacting this with the remainder, the reaction is carried out in the presence of a catalyst at a temperature not exceeding 400 DEG C., this being effected by cooling the dioxide prior to the catalytic reaction. In the apparatus shown, hydrogen sulphide is forced by a pump 1 through a three way cock 2 adjusted to supply the required amount to a burner 3 to which air is supplied by a blower 5, the heat of combustion being used to produce steam in a boiler 6. Sulphur dioxide so produced is mixed in a vessel 4 with the remainder of the hydrogen sulphide and passed through a chamber 7 filled, e.g. with bauxite, the sulphur formed being collected in a vessel 8. The waste gases, which may contain some residual sulphur vapour and some of the reacting gases pass through settling chambers 10 or through a second catalytic chamber; removal may be effected by active carbon. Specification 9768/84, [Class 90], is referred to.
通过燃烧硫化氢的部分产生二氧化硫,然后将其与剩余部分反应制备硫磺的制造过程中,反应在催化剂存在下进行,温度不超过400摄氏度,通过在催化反应之前冷却二氧化硫来实现。在所示装置中,硫化氢通过泵1被迫通过三通阀2,该阀被调整以向燃烧器3提供所需量的硫化氢,空气由鼓风机5供应,燃烧产生的热量用于在锅炉6中产生蒸汽。产生的二氧化硫与剩余的硫化氢在容器4中混合,通过填充了例如铝土矿的室7,并在容器8中收集形成的硫磺。废气,其中可能含有一些残留的硫蒸气和一些反应气体,通过沉降室10或通过第二催化室流过;可以通过活性炭进行去除。参考规范9768/84,[90类]。
