Raw materials for Glass Manufacturing:
Solvay’s Process: Practically following are the steps followed in soda ash production in the solvay’s process.

The Brine (i.e. Salt Solution) is allowed to react with ammonia to form ammoniated brine.
NaCl + H2O + NH3 — > NaCl + NH4OH
The ammoniated Brine is allowed to react with carbon […]

Raw materials for Glass Manufacturing:
Solvay’s Process: This process produces light soda ash. Soda Ash thus produced has a specific weight of 500 kg/m3. This specific weight is sufficient for using in detergent and chemical application. But for glass manufacturing higher specific weight of atleast 1000 kg/m3 is required.
The light soda ash produced in the solvay’s […]
