In the hydrogen sulfide removal process, the H 2 S is initially physically absorbed into the adsorbed water undergoing the dissociation according to following reactions: H 2 S (g) + H 2 O ↔ H 2 S (aq) H 2 S (aq) ↔ H + + HS -. HS - ↔ H + + S 2-. The formation of sulphur and water occurs by means of sulfide,
