The Solvay process or ammonia–soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3). The ammonia–soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. [ 1 ]
The Solvay process recycles its ammonia. It consumes only brine and limestone, and calcium chloride is its only waste product. The process is substantially more economical than the Leblanc process, which generates two waste products, calcium sulfide and hydrogen chloride. The Solvay process quickly came to dominate sodium carbonate production ...
Solvay, New York and Rosignano Solvay, the locations of the first Solvay process plants in the United States and in Italy, are also named after him. Solvay died at Ixelles at the age of 84 and is buried in the Ixelles Cemetery. The portrait of participants to the first Solvay Conference in 1911. Ernest Solvay is the third seated from the left.
The Solvay process was developed by the Belgian industrial chemist Ernest Solvay in 1861. In 1864, Solvay and his brother Alfred constructed a plant in Charleroi Belgium. In 1874, they expanded into a larger plant in Nancy, France. The new process proved more economical and less polluting than the Leblanc method, and its use spread.
Forgive me if this is just a stupid mistake of mine, but on the wiki page for Sodium Carbonate, under the Hou process is: "Hou's Process is the most common current process in the world to produce sodium carbonate.", which goes against the claim in the introduction of this page that 3/4ths of the world's supply is made via the Solvay process.
Solvay Process Company office building around 1889. The Solvay Process Company was a joint venture between Belgian chemists Ernest and Alfred Solvay, who owned the patent rights to the Solvay process, and Americans William B. Cogswell and Rowland Hazard II.

It is a product of the Solvay process used to produce sodium carbonate: [3] CO 2 + 2 NH 3 + 2 NaCl + H 2 O → 2 NH 4 Cl + Na 2 CO 3 Not only is that method the principal one for the manufacture of ammonium chloride, but also it is used to minimize ammonia release in some industrial operations.
