Dry Desulfurization Unit
In natural gas purification, hydrated iron oxide is commonly used as the desulfurizing agent.
Application
Through an oxidation reaction, it removes H2S from natural gas.
In a typical surface processing train the sequence is: Wellhead → Separation → Treating → Metering → Pipeline.
Scope of supply
- This method is particularly suitable for applications with low gas processing capacity and low H2S content, such as single-well desulfurization, ultra-low sulfur removal, and fuel gas desulfurization within stations, etc.
Capacity, design conditions and scope of supply are confirmed per project.
