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 company was founded as Nihon Soda Kogyo Co., Ltd., a producer of soda ash in 1918 by Katsujiro Iwai. It changed name in 1936 to Tokuyama Soda Co., Ltd. and in 1994 to its present name. [4] It is listed on the Tokyo Stock Exchange and is a component of the Nikkei 225 stock index. [5]
American Natural Soda Ash Corporation (ANSAC) operates as the international distribution arm for three US manufacturers of natural soda ash produced from trona [1] deposits in Green River, Wyoming, the trade name for sodium carbonate Na 2 CO 3, is an essential raw material used in the manufacture of glass, detergents, and several sodium-based chemicals.
Trona is a common source of soda ash, which is a significant economic commodity because of its applications in manufacturing glass, chemicals, paper, detergents, and textiles. It is used to condition water. It is used to remove sulfur from both flue gases and lignite coals. [19] [20] It is a product of carbon sequestration of flue gases. [21]
Soda ash was used since ancient times in the production of glass, textile, soap, and paper, and the source of the potash had traditionally been wood ashes in Western Europe. By the 18th century, this source was becoming uneconomical due to deforestation, and the French Academy of Sciences offered a prize of 2400 livres for a method to produce ...
The ammonia-soda process was first patented on 30 June 1838 by Harrison Gray Dyar and John Hemming, [3] [4] who carried it out on an experimental scale in Whitechapel. Many attempts were soon after made in the same direction, both in England and on the continent of Europe, the most remarkable of which was the ingenious combination of apparatus ...
