Configurations, systems, and methods for recovery of elemental sulfur using a solvent

摘要

Elemental sulfur carrying capacity of a hydrocarbonaceous solvent is improved by first loading the solvent with sulfur and subsequent hydrotreatment under conditions that convert at least some of the elemental sulfur in the sulfur loaded solvent to hydrogen sulfide while preserving at least 95% of the monoaromatic and polyaromatic components in the solvent.
