Abstract
A method of producing micronized sulphur wherein elemental sulphur is dissolved in a solvent for sulphur to produce a sulphur-solvent solution and precipitation of the dissolved sulphur is effected or controlled by manipulation of at least one of pressure, temperature or water content in the solvent to produce the micronized sulphur.
Claims10
A method of producing micronized sulphur comprising:
- dissolving elemental sulphur in a solvent for sulphur to produce a sulphur-solvent solution, said solvent being selected from the group consisting of anhydrous ammonia, hydrous ammonia, liquid sulphur dioxide, liquid carbon dioxide, supercritical carbon dioxide, carbon disulphide, dimethyldisulphide and mixtures thereof;
- controlling precipitation of said dissolved sulphur in said sulphur-solvent solution by manipulation of at least one of pressure, temperature or water content to produce micronized sulphur;
- and
- recovering micronized sulphur.
