About the sodium chloride content in soda ash
Thread Content
I would like to ask the experts in the forum, which domestic manufacturer produces soda ash with a sodium chloride content lower than 0.3%? Don't you know it can be so low?
This can definitely be done, and some manufacturers have already done it. In my opinion, there is absolutely no problem with liquid-phase hydrated heavy ash!
Is there any light gray that can meet this indicator?
It can be achieved with the current technology, but it is not very stable and very uneconomical.
It is uneconomical to reduce the salt content of light ash to less than 0.3. No one is willing to do it, especially the joint-alkali enterprises. They will definitely not do it.
A salt content of less than 0.3% is a requirement for heavy ash, and the lowest can be reduced to less than 0.1%.
