Cryo-DAC®

A pressure swing amine process driven by the cryogenic pumping with LNG cold

Air

(CO2 < 100ppm)

Air

CO2 (400ppm)

Absorbent

Advantages

• Low regeneration temperature
  
• Amine can accept water in air
• CO2 with high pressure & purity is product

No further compression and purification
