METHOD OF PRODUCING GRANULAR SULPHUR Russian patent published in 2015 - IPC C01B17/02 B01J2/06 

FIELD: chemistry.

SUBSTANCE: disclosed is a method of producing granular sulphur by adding liquid sulphur to water. Liquid sulphur under pressure of 900 Pa to 9000 Pa flows from an opening with a diameter of 0.5 mm to 2.5 mm in form of a vertical solid jet and falls into water. The distance between the exit point of the jet of sulphur and the water surface is not more than 80 mm. The obtained spherical sulphur granules are the best geometric shape of solid sulphur, which is characterised by the best mass to volume ratio and the best mechanical strength. The uniformity of the grain-size composition and the spherical shape of the particles improve the accuracy of feeding granular sulphur with any type of feeder.

EFFECT: obtaining granular sulphur in the form of spherical particles of a given diameter.
