Ernest Solvay

Died 26 May 1922 at age 84 (born 16 Apr 1838).Belgian industrial chemist who invented the Solvay Process (1863), a commercially viable ammonia-soda process for producing soda ash (sodium carbonate), widely used in the manufacture of such products as glass and soap. Although a half-century before, A.J. Fresnel had shown (1811) that sodium bicarbonate could be precipitated from a salt solution containing ammonium bicarbonate, many engineering obstacles had to be overcome. Solvay's successful design used an 80 foot tall high-efficiency carbonating tower in which ammoniated brine trickled down from above and carbon dioxide rose from the bottom. Plates and bubble caps helped create a larger surface over which the two could react forming sodium bicarbonate.
