Abstract: Disulfide solvents may be particularly effective for dissolving deposits comprising elemental sulfur, but the extreme odor of these solvent may make their use rather problematic. Solvent blends comprising at least one disulfide solvent, amine solvent, ketone solvent, and ester solvent may afford a less obnoxious odor and not appreciably compromise the sulfur dissolution capabilities.

Excessive odor resulting from a solvent residue upon a surface may be alleviated by contacting the surface with at least one oxidant. Odor balance may also be restored to at least partially spent solvent blends by introducing additional ester solvent, which may convert a biphasic mixture into an emulsion comprising the disulfide solvent.
