We speak about the "Solvay process" because in the 1860s, Ernest Solvay invented a new soda ash process using ammonia as processing agent - enabling CO 2 to substitute Chlorine at the Sodium atom (also called "ammonia process"). This process replaced the previous Leblanc process as Solvay process is much less impactful for the environment.

The Frasch process is a method to extract sulfur from underground deposits. It is the only industrial method of recovering sulfur from elemental deposits. Most of the world's sulfur was obtained this way until the late 20th century, when sulfur recovered from petroleum and gas sources became more commonplace (see Claus process).
