Micronized sulphur powder and method of production of same

摘要

A process is provided for the production of a micronized sulphur powder product as well as a micronized sulphur cake intermediate. Production of the micronized sulphur powder using this process, which comprises preparation of a micronized sulphur emulsion from molten sulphur and a dispersant solution, from which the dispersant solution is subsequently removed, produces a product superior quality, and the method of production itself has enhanced safety and economic attributes.

主权项

1. A method for the production of micronized sulphur particles, the method comprising:
(a) producing an emulsion of liquid sulphur in an aqueous dispersant solution above a melting point of sulphur, wherein dispersant is present at between about 1 and about 100 parts per thousand of the dispersant solution; (b) cooling the sulphur emulsion to a temperature below the melting point of sulphur to solidify sulphur particles; and (c) separating the dispersant solution from the sulphur particles to leave a sulphur particle cake, wherein the dispersant aids the separation of water from the sulphur particles.
