Gas absorption

Absorption is a primary method for removing gaseous components from a stream using a solvent. This unit separates a CO2/air mixture using water in a packed bed column with continuous solvent regeneration.

• separation of CO2/air mixture by absorption in counterflow with water
• production of gas mixture using CO2 from compressed gas cylinder and ambient air
• adjustment of mixing ratio using valves
• compressor for delivering the gas mixture into the absorption column
• DURAN glass absorption column (packed bed) and desorption column
• continuous solvent regeneration in circuit with desorption column under vacuum
• 1 pump for desorption column and 1 pump for returning solvent to absorption column
• water temperature control with heater and refrigeration system
• refrigerant R513A, GWP: 631
