Some highly-unconventional ways of producing this compound include the nepheline syenite route and the new Asahi process.
Some highly-unconventional ways of producing this compound include the nepheline syenite route and the new Asahi process. A modified version of the standard method for producing it is referred to as Hou's process or the dual process. The most cost-effective way to produce it is often through the purification of trona ore, particularly in areas like the rich Green River Basin of Wyoming. The standard industrial method allows for the recycling of ammonia, which led it to replace the older Leblanc process. That ammonia is dissolved ►in brine and subjected to a bubbling up of carbon dioxide. FTP, name this compound produced by the Solvay process, which is sometimes referred to as soda ash.
