SOLIDS REMOVAL USING SOLVENT BLENDS COMPRISING A DISULFIDE SOLVENT

Solids dissolution may be promoted using a solvent blend comprising a disulfide solvent, particularly additional solids present in combination with elemental sulfur deposits. The solvent blends may comprise at least one disulfide solvent, at least one amine solvent, at least one ketone solvent, at l...

Zusammenfassung:	Solids dissolution may be promoted using a solvent blend comprising a disulfide solvent, particularly additional solids present in combination with elemental sulfur deposits. The solvent blends may comprise at least one disulfide solvent, at least one amine solvent, at least one ketone solvent, at least one ester solvent, and optionally water. Solids dissolution methods may comprise: identifying one or more solids in addition to elemental sulfur to be contacted by the solvent blend; adjusting a composition of the solvent blend to afford selectivity for dissolution of at least a portion of the one or more solids; and contacting the solvent blend with elemental sulfur and the one or more solids to promote at least partial dissolution thereof.
