Soda ash light, also known as anhydrous sodium carbonate is the inorganic compound and an alkali chemical with the formula Na2CO3. It is a white, odorless granular powder that is soluble in water. Soda ash light refined from the mineral trona or from naturally occurring sodium carbonate-bearing brines. Either natural or synthetic, soda ash is an important raw material for the manufacture of flat glass and fiberglass, both used in the automotive and construction industry. Also used for the manufacture of chemicals, detergents, and other major industrial products.
Naturally in the arid region sodium carbonate occurs. It is observed in areas where the lakes evaporate in the form of deposits. It is found in large natural lakes in Wyoming. Sodium carbonate deposits exist in large quantities in various parts of the world, but primarily the USA, China, Botswana, Uganda, Kenya, Mexico, Peru, India, Egypt, Southern Africa, and Turkey. It is present in sodium minerals and sodium-rich waters.
There are five types of sodium carbonate deposits, which are crystalline shoreline, surface brines, buried ore, shallow lake-bottom crusts, and surface efflorescences. Even though over 95 deposits of sodium carbonate have been found worldwide, the United States still has the largest buried trona deposit in the world in Green River, Wyoming and it is sufficient to sustain domestic soda ash demand for centuries. Soda ash is only derived from natural sources in Botswana, China, Kenya, and The United States.
In the US soda ash light ranked 10th in 2011 in the list of domestic production of all chemical products. Although soda ash accounted for about 2% of the estimated total of 74 billion U.S. dollars, it makes a substantial contribution to America’s gross domestic product in many goods. The production of soda ash appears to be increasing with population and gross domestic product. Domestic consumption of soda ash for several years has been relatively low, rise about 1 percent per year.
How To Produce Soda Ash Light?
There are two processes that can produce soda ash light and it is widely used by Soda Ash light Suppliers. The first process called Solvay Process has been found in 1861 by a Belgian Chemist named Ernest Solvay. In this process, ammonia reacts with sodium chloride with the aid of calcium carbonate. Sodium bicarbonate is produced and it is then heated and converted to soda ash light. The second process was found by Chinese chemist Hou Debang in 1930 and the process named by his name, Hou Process. Basically, sodium bicarbonate is formed using carbon dioxide and a saturated solution of sodium chloride and ammonia. Then heat the precipitated sodium bicarbonate, yielding pure soda ash light. The Hou process is a modified version of the Solvay process.
Soda ash light and dense are the two main grades for soda ash. Both have a similar molecular weight, a similar solubility, and contain the same pH when calculated by weight. The difference between density and particle size between grades. The ammonia-alkali method is usually used to produce soda ash, which involves salt and limestone as raw materials to produce soda ash light by chemical synthesis method, and soda ash dense is produced by solid-phase water method.
The several contents and grades of soda ash light usually depend on the supplier because of different processes uses. Several properties such as NaCl and Fe contents will vary from each supplier. Therefore on the industrial scale, it is very important to select reliable soda ash light suppliers.
Fun Facts on Soda Ash Light
- Natural soda ash wash used as a desiccant in the early Egyptians for the mummification process.
- In 1868 the first natural soda ash operation was in the United States, Fallon, Nev.
- The world’s largest trona deposit in Wyoming was discovered by an accident! Exploration teams were actually searching for oil and gas in that area.
- The world accounted for 76% of the soda ash production in China, Germany, Russia, and the United States.
