Technical Positioning

MDEA is positioned around gas treatment duty and process compatibility, explaining how it supports gas sweetening, acid gas removal, CO₂ / H₂S treatment, and amine-system reliability.

Technical Role

Amine solvent for selective acid gas removal in refinery and gas-plant treating systems.

Performance Focus

Selective H₂S absorption, CO₂ management, solvent stability, and regeneration behavior.

Control Parameters

Acid gas loading, solvent concentration, foaming tendency, corrosion risk, and heat-stable salts.

Process Flow

Sour gas feed → amine absorption → lean/rich amine exchange → regeneration → solvent recirculation.
