Producing Sodium carbonate (Na2CO3)

Na2CO3: Sodium carbonate

for Glass, paper, and detergent

React carbon dioxide to ammonia saturated solution of sodium chloride.

CO2 + NH3 + H2O + NaCl NaHCO3 + NH4Cl

Bake deposited sodium bicarbonate.

2NaHCO3 Na2CO3 + H2O + CO2

Add calcium hydroxide to produced solution.

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

Ammonia and calcium chloride is recovered again for reusing them.
