A few British and French plants operated in 1840-1860, but without success The ammonia-soda process is usually called the Solvay process because in 1865 Ernest Solvay started the first really successful plant at couillet in Belgium In 1874, the first successful ammonia-soda plant was erected in ,
The Solvay process, also referred to as the ammonia-soda process, is the major industrial process for the production of soda ash (sodium carbonate)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)
Solvay is a global leader in Soda Solvay® anhydrous sodium carbonate production, using two different processes: the traditional Solvay ammonia process and the refining of natural Trona (or sesquicarbonate)
