Specialized system designed to capture carbon dioxide (CO₂) emissions from industrial flue gases. Employs methods such as chemical absorption, adsorption, membrane separation, and cryogenic distillation to separate CO₂ from other gases. Specifically optimized for treatment of flue gases from high-temperature, low-pressure processes such as rotary kilns (lime kilns), which have low CO₂ concentrations and contain impurities like NOx and SO₂.
