🧪 Packed-Bed CO2 Adsorption: Breakthrough Curve and Mass Balance (2D side view)

2D side view of a packed column of sorbent pellets capturing CO2 from a gas stream. Change flow, CO2 content, temperature, humidity and pellet size, watch the loading front move to the outlet and read the breakthrough curve, the pressure drop and the mass balance; switch to hot regeneration to release the gas. Same engine file as the 3D page, with five in-page numerical checks.
