ABSTRACT:
A method for the removal of moisture associated with sulfur and for the melting of solid sulfur. A flow of molten sulfur is circulated through a mixing device in a substantially spiral flow wherein the circulating molten sulfur forms a continuous vortex of molten sulfur. Particulate solid sulfur with or without associated moisture, either as such or in the form of an aqueous slurry or moisture-containing liquid sulfur is fed into the vortex of circulating molten sulfur. Sulfur is discharged from the mixing device and any associated moisture is evaporated and separates from the sulfur. Molten sulfur substantially free of moisture is recovered.
