for Glass, paper, and detergent

React carbon dioxide to ammonia saturated solution of sodium chloride.

CO2 + NH3 + H2O + NaCl right NaHCO3 + NH4Cl


Bake deposited sodium bicarbonate.

2NaHCO3 right Na2CO3 + H2O right + CO2 right


Add calcium hydroxide to produced solution.

2NH4Cl + Ca(OH)2 right 2NH3 + CaCl2 + H2O
