Dissolvine chelates are used in liquid redox sulfur recovery processes

Dissolvine chelates are used in liquid redox sulfur recovery processes for removal of H2S.

In commercially available processes, ferric ions oxidize H2S to elemental sulfur. Dissolvine chelating agents activate the ferric ions and prevent them from precipitating.
