Zeolite Adsorption Column: 2D Breakthrough Curve Simulator

Zeolites separate gas mixtures purely by molecular size: a crystalline lattice of uniform pores admits any molecule smaller than its aperture and sterically rejects everything larger. This 2D companion simulation solves the actual fixed-bed mass-balance equations for a real gas mixture — water, carbon dioxide, nitrogen, oxygen, methane and branched isobutane, each with its true kinetic diameter — as it flows through a packed zeolite column. Instead of watching individual molecules bounce off a membrane in 3D, you watch the mass-transfer front itself: a scrolling space-time map of bed saturation, and the live breakthrough curve every adsorption engineer actually reads off a real column. Set the pore aperture to match real industrial gradings (3A, 4A, 5A, 13X-scale), toggle which species are in the feed, and trigger bed regeneration to desorb and reset, exactly as a pressure- or temperature-swing plant does.
