CO₂ + H₂O → H₂CO₃① CO₂ dissolves in the pellet's surface water film

H₂CO₃ + 2NaOH → Na₂CO₃ + 2H₂O + heat② fast neutralisation by NaOH (catalyst)

Na₂CO₃ + Ca(OH)₂ → CaCO₃ + 2NaOH③ slow step: lime locks CO₂ as chalk, regenerating NaOH

Radial flow: gas crosses the bed from the centre tube outwards, so the violet front grows as a ring. EN 14143 rating: 140 min at 4 °C, 40 m.
