Solvay is a global leader with over 7 Mt of Soda Solvay® anhydrous sodium carbonate produced every year using two different processes: the traditional Solvay ammonia process and the refining of a primary source of sodium carbonate, the Trona. Today, it is shipped to more than 90 countries, using every form of transport imaginable.
Soda Solvay® is available in 2 different grades – dense and light – to meet its customers’ specifications in accordance with all applicable safety, health and environmental standards.
As well as being present in many major consumer markets, Solvay's global supply chain capability benefits from multiple sourcing opportunities and a wide network of local warehouses to give an even better service to its customers, both across Europe, the USA, and, even more importantly, in many export destinations.
It also addresses a strong demand of global glass and detergent companies to reduce its carbon footprint by developing excellence manufacturing programs which reduce emissions and energy consumption. Moreover, Solvay is studying new applications of sodium carbonate in close collaboration with its customers.
The dense grade has a bulk density of ~1 t per m3 and a Particle-Median-Diameter (D50) of 300 to 500 microns.
Soda Ash Dense is the grade preferred for glass manufacture because its granular properties make it widely dust-free and reduce the risks of segregation during transport and handling.
The light grade has a bulk density of ~0,5 t per m3. The D50 of approximately 100 microns is very well suited for detergent and chemical applications.
A pharmaceutical grade of sodium carbonate anhydrous is also available. It is produced in a dedicated production facility in Dombasle (France).
