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 ]
Sodium carbonate (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na 2 CO 3 and its various hydrates.All forms are white, odourless, water-soluble salts that yield alkaline solutions in water.
Solvay Chemical continued soda ash production through the 20th century. By 1980, the demand for soda ash plummeted. By 1985, the company had lost $55 million over the previous three years, forcing Allied Chemical (AlliedSignal at the time) to close and demolish the plant, dismissing 1,400 employees.

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.
Demand for soda ash increased, and the supply of sodium sulfate had to increase in line. Therefore, in the 19th century, the large-scale Leblanc process , producing synthetic sodium sulfate as a key intermediate, became the principal method of soda-ash production.
If all the production were exported to Europe, it would increase the key glass raw material by around 25%. [6] Around 1,000 people are employed by the company. [2] The trona ore reserve of Kazan Soda Elektrik is the world's second largest. [2] The plant is the biggest soda ash production facility in Europe. [2]
Soda ash is used as a raw material in a variety of industrial products and consumer goods, [4] including glass (47%), chemicals (30%), soap (7%), and paper. [ 2 ] [ 3 ] Other products are sodium percarbonate (2 Na 2 CO 3 · 3 H 2 O 2 ), hydrogen peroxide (H 2 O 2 ), and other chemicals to soap and detergent production.
