Ferric Chelate Desulfurization Unit
The Ferric Chelate Desulfurization process uses an iron-based chelating agent as the desulfurizer.
Application
Through redox reactions, it absorbs H2S and converts it into elemental sulfur.
In a typical surface processing train the sequence is: Wellhead → Separation → Treating → Metering → Pipeline.
Scope of supply
- This technology is widely applied in natural gas purification, associated gas treatment, recovery of sulfur-containing flare gas, deep desulfurization of acid gas tail gas, refinery gas desulfurization, and the development of medium- to high-sulfur gas fields.
Capacity, design conditions and scope of supply are confirmed per project.
