Soda ash production and sulfate ions
Thread Content
In soda ash production, are there any requirements for sulfate in the brine? What are the specifications?
The sulfate content is generally controlled at 5–7 g/L.

High sulfate concentration leads to rapid scaling in the distillation column and a shortened operating cycle.
