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 ...
Trona (trisodium hydrogendicarbonate dihydrate, also sodium sesquicarbonate dihydrate, Na 2 CO 3 ·NaHCO 3 ·2H 2 O) is a non-marine evaporite mineral. [4] [6] It is mined as the primary source of sodium carbonate in the United States, where it has replaced the Solvay process used in most of the rest of the world for sodium carbonate production.
Born in Rebecq, he was prevented by his acute pleurisy from going to university. He worked in his uncle's chemical factory from the age of 21. In 1861, he, along with his brother Alfred Solvay, developed the ammonia-soda process (also known as the Solvay process) for the manufacturing of soda ash (anhydrous sodium carbonate) from brine (as a source of sodium chloride) and limestone (as a ...
The Solvay Process Company was an American chemical manufacturer that specialized in the manufacture of soda ash. A major employer in Central New York , the company was key in the origin of the village of Solvay, New York , where it was headquartered.
