Soda Ash (Sodium Carbonate) is produced by two main methods, both of which produce chemically identical Soda Ash. Sodium Carbonate is a basic salt. Its aqueous solution is clear and colorless, and its chemical formula is Na2CO3.
The Production of Soda Ash
Natural Soda Ash production is the first way of supplying soda ash. Which is produced by extracting naturally occurring Trona ore and then processing this via a simple process of filtering, concentration, crystallization, and drying into Soda Ash which can be sold. Today, this accounts for around 30% of global production, and natural Soda Ash is only produced in Wyoming, the USA, and Turkey.
The second one is Synthetic Soda Ash production, which is produced using a chemical production process, in which salt (sodium chloride) is reacted with limestone (calcium carbonate) and coking coal in the presence of ammonia to produce synthetic Soda Ash. Synthetic Soda Ash accounts for about 70% of global production and is costlier and far more energy and water-intensive production process than natural production methods. As of 2021, the global production of Soda Ash is estimated to reach 62.2 million MT per year.
Grade of Soda Ash
How it is used;
Soda Ash is used in thousands of everyday products worldwide and ingredient in many products which we all use every day.
Over half of all Soda Ash production is used in glass manufacturing, but it is also used in a wide range of other products, such as powdered detergents and soaps and rechargeable batteries, as well as being used extensively in metallurgical processes, and across the food, cosmetic and pharmaceutical industries. Importantly, Soda Ash is increasingly being used to improve our environment and reduce polluting emissions by removing Sulphur dioxide and other harmful chemicals from exhaust fumes in shipping and other industrial flue gas emissions.
Grades of Soda Ash;
Soda Ash can vary in density, size, and shape. Mostly can find in two grades; Soda Ash Dense (SAD) and Soda Ash Light (SAL). This flexibility allows it to be used in a variety of everyday products
Soda ash light: Soda Ash Light is used for the production of detergents, chemicals, soaps, textile, paper, food, and other sodium compounds and for the casting industry, and oil refineries.
Soda ash dense: Soda Ash Dense is preferred for all kinds of glass manufacture like flat glass, float glass, container glass, etc.
