ABSTRACT:
A process comprising contacting a solvent with a sulfur stream comprising sulfur and a contaminant, separating the sulfur from at least some of the contaminant and at least some of the solvent, thereby producing a decontaminated sulfur stream, contacting the decontaminated sulfur with a washing agent, and separating the sulfur from at least some of the washing agent, thereby producing a purified sulfur stream comprising elemental sulfur.
