Manufacturing of synthetic soda ash
… was to study the manufacturing of synthetic soda ash (sodium carbonate, Na2CO3) on an industrial scale. Currently all Soda ash that is used in South Africa for manufacturing glass is imported at a high cost, and the company Nampak Wiegand Glass (South Africa) is investigating the possibility …

The utilization of aplite in ladle desulfurization of cast iron
The desulfurizing powers of aplite, aplite-soda ash mixtures, and aplite-dehydrated lime combinations when added to a ladle of cast iron were tested. Ladle conditions were simulated by melting cast iron in a crucible and introducing the reagent mixtures into the molten metal by means of a cast iron …

Aging and Copper Corrosion By-Product Release: Role of Common Anions, Impact of Silica and Chlorine, and Mitigating Release in New Pipe
… Chemical pretreatments using lime, caustic, soda ash or chlorine reduced copper release by as much as 84% compared to new pipes without pretreatment.

Defluoridation of typical eastern Virginia groundwater
… other methods of pH adjustment such as employing soda ash should be considered. Aluminum was detected in the unfiltered treated water, perhaps in sufficient concentrations to cause problems in the distribution system, but further testing of filtered samples is needed. Sulfates were low in the raw …

Effect of Calcium on Arsenic Release From Ferric and Alum Sludges and Lagoons
… As the pH is increased with addition of caustic soda or soda ash, soluble arsenic concentration increases dramatically. However, as the pH is increased with lime, very little arsenic is released back into the water. On the basis of previous research this phenomenon might be attributed to the …

Development of methods for the characterization of melting batches
… developed. It was found that the mass loss of soda ash detected in a vertical tube furnace started at a lower temperature and was completed at a higher temperature than suggested by the results measured by thermogravimetric analysis (TGA). These new characterization methods not only open …
