Solvay Process of Producing Commercial Grade Minerals


We’re going to take a look at the Solvay process of producing commercial grade sodium carbonate from salt water, limestone, coal, and ammonia. To start out, the Solvay process is a series of chemical reactions that produce sodium carbonate, or soda ash. Here, we have sodium carbonate, which we can also call soda ash. That’s what we’re working toward.


Right here you see that the Solvay process is a series of chemical reactions that produce sodium carbonate. We’re producing sodium carbonate. Here is our series of chemical reactions that have to occur for that to happen. This whole process here is fueled by burning coal. Coal gets converted to coke, gas, coal, tar, and ammonia. Here are the steps: You start out right here with the thermal decomposition of limestone.


Here, we have limestone that’s being decomposed. Then, we have sodium chloride getting saturated with ammonia and carbon dioxide. Here, we have carbon dioxide and ammonia. There’s that saturation process. We have sodium ions in the solution combining with the bicarbonate. You see that process playing out right there. Then, the sodium bicarbonate precipitates, is collected, and thermally decomposes to sodium carbonate.


That’s this final process right there. As you can see, this is the Solvay process, because we have a series of chemical reactions producing soda ash. Soda ash is used in making glass, paper, chemicals, and detergents, so you can see why it’s important to go through a process to make it.
