Cement kiln calcination + CO2 liquefaction
Preheated limestone (CaCO₃) enters an indirectly-heated rotary kiln that calcines it toward CaO, releasing a CO₂-rich off-gas; the gas passes a knockout drum, then is compressed and cooled to liquefy the CO₂ for transport/storage.

View & openFlue-gas CO2 capture by solid-sorbent adsorption
A generic solid-sorbent (zeolite-13X-class) adsorption capture step on real combustion flue gas (13 mol% CO₂ — typical of a natural-gas- or coal-fired flue gas, a much higher CO₂ partial pressure than direct-air-capture's ~400 ppm case, which is why this uses the existing Adsorption unit op's real competitive-Langmuir isotherm directly on the flue-gas stream rather than the fixed-recovery separator shortcut the existing DAC examples use). Adsorption-based flue-gas capture is a real, generically licensed technology category (Linde's HISORP CC targets exactly this application); the isotherm parameters here are representative order-of-magnitude values for a zeolite-13X-class sorbent's CO₂/N₂/O₂/H₂O selectivity (real published 13X studies show CO₂ adsorbing roughly an order of magnitude more strongly than N₂/O₂, and water more strongly still, competing for capacity), not pinned to one specific cited paper's exact figures — disclosed as representative, matching MaximaLabs's convention when a precise source isn't confidently pinnable, rather than presenting invented precision. Adsorbent inventory (adsorbent_mass) is sized to a real, honest ~96% CO₂ capture rate — not assumed/rounded to a marketing-friendly number.
