The process is based on desorption — the transfer of dissolved CO₂ from water into the gas phase.
Water enters the top of the unit and flows over packing material as a thin film. Air is supplied from below and strips the carbon dioxide.
Higher contact surface area increases removal efficiency.
The decarbonator is a vertical column filled with packing (Pall or Raschig rings) to enhance mass transfer.
Main components: • column vessel
• packing media
• water distribution system
• air supply system
• drainage and outlet
Applications: • hydrogen-cation exchange systems
• combined ion exchange processes
• chemical demineralization systems
Equipment is manufactured from corrosion-resistant materials:
• carbon steel with anti-corrosion coating
• stainless steel
• polymer materials
Packing is made of ceramic or polymer materials.
Main parameters:
• capacity — up to 300 m³/h
• air flow rate — proportional to water flow
• operating temperature — up to 40 °C
• CO₂ removal efficiency — up to 99%+
