Product & Technical Features

MDEA Chemical Absorption
- Selectively removes H₂S and CO₂ with solvent regeneration; suitable for high acid gas content and large-scale processing
Dry Desulfurization
- Iron oxide-based solid adsorbents in multi-stage configuration; suitable for low H₂S content or polish removal
Acid Gas Utilization
- Recovered acid gas can be routed to Claus sulfur recovery units to produce elemental sulfur, reducing direct emissions
Flexible Process
- Acid gas removal depth customized based on H₂S/CO₂ ratio and sales gas specifications to meet GB 17820 and other standards
