Abstract:
1. A method for the production of micronized sulphur particles, the method comprising: heating solid sulphur stock to a temperature above a melting point of sulphur such that the sulphur stock melts and forms liquid sulphur; preparing a dispersant solution by mixing a dispersant agent with solvent in selected proportions; containing the dispersant solution under pressure and raising a temperature of the dispersant solution to a temperature about equal to the temperature of the liquid sulphur; blending the liquid sulphur and dispersant solution together to produce an emulsified sulphur suspension; cooling the emulsified sulphur suspension to a temperature below the melting point of sulphur; removing the dispersant solution from the emulsified sulphur suspension to leave sulphur particles; and drying the sulphur particles.
