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 ]
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.
Besides, the business also has a production capacity of 630 tons per day of dense ash (Na 2 CO 3.H 2 O), which is an essential raw material for glass making, and 160 tons per day of Refined Sodium Bicarbonate. [9] ICI Pakistan's soda ash business caters to approximately 70% of the country's total soda ash requirement.
In November 2007, Nirma purchased American raw materials company Searles Valley Minerals Inc., making it among the top seven soda ash manufacturers in the world.

Trona (trisodium hydrogendicarbonate dihydrate, also sodium sesquicarbonate dihydrate, Na 2 CO 3 ·NaHCO 3 ·2H 2 O) is a non-marine evaporite mineral. [4] [6] It is mined as the primary source of sodium carbonate in the United States, where it has replaced the Solvay process used in most of the rest of the world for sodium carbonate production.
Knowing that American industry was importing soda ash from Europe, Cogswell envisioned utilizing the process in America. After several refusals, Cogswell eventually secured American rights to the Solvay process. He obtained capital to build a production facility from Rowland Hazard II, scion of the Hazard family. Rowland Hazard was the major ...
ICL serves primarily three markets: agriculture, food and engineered materials. [9] ICL produces approximately a third of the world's bromine, and is the world's sixth-largest potash producer. [10] It is a manufacturer of specialty fertilizers and specialty phosphates, flame retardants and water treatment solutions. [11]
