  • Solvay process — Wikipedia Republished // WIKI 2

    The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash). The ammonia-soda process was developed into its modern form by Ernest Solvay during the 1860s. The ingredients for this process are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from mines).
