Advanced Amine Technology Carbon Capture Plants - AAT

Pentair Advanced Amine CO₂ Capture Plant relies on absorption technology, which employs concentrated monoethanolamine (MEA) to react with the carbon dioxide (CO₂) and extract it from the gas stream.

After capturing the CO₂ in the MEA solution, it is transferred to the stripping (de absorber) unit. In this unit, the solution’s temperature is raised to reverse the chemical reaction that occurred during absorption, thereby releasing the CO₂ from the MEA solution. The gas being released from the stripper is a highly concentrated stream containing roughly 99% pure CO₂.

This concentrated stream can be used in its gaseous form or further purified and liquefied to meet the standards for food and beverage-grade CO₂ specified by regulators. Purification is the final step, consisting of a compression, drying, and liquefaction process, increasing the purity to food-grade and Northern Lights specification2 (99.999% (v/v)).

• Pentair patented component, NOxFlash, and highly concentrated amine (monoethanolamine - MEA) allow for high oxygen, O₂, concentrations in the flue gas.
  
  
• Patented design Pentair flue gas heated reboiler efficiently utilizes heat from flue gas, eliminating the need for steam.
  
  
• NOxFlash efficiently removes nitrogen dioxide, NO₂, resulting in a high purity CO₂ and reducing degradation of amine.
  
  
• Pentair Amine Systems are designed to produce food-grade quality CO₂, as per ISBT and EIGA specifications.
  
  
• Plant traditional sizes (measured as liquid food-grade CO₂ produced): 500 - 4500 kg/h. Other capacities are available upon request.
