Abstract
A system and process are disclosed for selective removal and recovery of HS from a gaseous volume, e.g., from natural gas. Anhydrous organic, sorbents chemically capture HS gas to form hydrosulfide salts. Regeneration of the capture solvent involves addition of an anti-solvent that releases the captured HS gas from the capture sorbent. The capture sorbent and anti-solvent are reactivated for reuse, e.g., by simple distillation.
