Solvay Process for the Production of Sodium Carbonate
- Sodium carbonate, Na2CO3, has a number of uses but its most common use is in the production of glass.
- Since the 1860's, sodium carbonate has been produced using the Solvay Process.
- The Solvay Process is a continuous process using limestone (CaCO3) to produce carbon dioxide (CO2) which reacts with ammonia (NH3) dissolved in brine (concentrated NaCl(aq)) to produce sodium carbonate.
- The steps in the Solvay Process are:
- Brine Purification
- Sodium Hydrogen Carbonate Formation
- Sodium Carbonate Formation
- Ammonia Recovery
