MDEA Acid Gas Removal Unit
In natural gas processing and purification, natural gas typically contains impurities—particularly H2S, CO2, and organic sulfur compounds, collectively referred to as acidic components.
Application
The MDEA acid gas removal unit consists primarily of an absorption section and a regeneration section.
In a typical surface processing train the sequence is: Wellhead → Separation → Treating → Metering → Pipeline.
Scope of supply
- It removes acidic components by allowing the MDEA absorbent to react chemically with the acid gases, achieving efficient acid gas removal.
- This is a widely adopted process for acid gas treatment in natural gas purification.
Capacity, design conditions and scope of supply are confirmed per project.
