    Abstract: A process for improving the smell of a stream of elemental sulphur comprising an organic polysulphide and/or a thiol, the process comprising the following step: (a) heating the stream of liquid elemental sulphur comprising an organic polysulphide and/or a thiol at a heating temperature in the range of from 360 to 700° C., at a pressure that is sufficient to maintain a liquid elemental sulphur phase to obtain heat-treated elemental sulphur.

    Abstract translation: 一种用于改善包含有机多硫化物和/或硫醇的元素硫气流的方法,该方法包括以下步骤:(a)在下列步骤中加热包含有机多硫化物和/或硫醇的液体元素硫流: 加热温度在360-700℃的范围内,在足以保持液态元素硫相以获得热处理的元素硫的压力下。
