Can liquid raw materials be used for sodium sulfite in the ion-exchange membrane caustic soda process?
Thread Content
I saw online that liquid sodium sulfite is available for sale; we use the solid version, which needs to be unloaded at the site, and mixing takes place during each shift, resulting in high labor intensity. If liquid raw material were used, it would be much simpler. Does your factory use it? What is the difference between liquids and solids? What are the impurities in liquids?
It is best not to use a liquid sodium sulfite solution. First, transportation costs will increase exponentially; second, sodium sulfite solutions tend to absorb oxygen, which reduces their reducing effect.
No problem, it can be used; compare the usage costs.
The ingredients make things easier, but doesn’t transporting the liquid volume, as well as unloading it, require manual labor? Cost issues. Unless the liquid is from the neighboring factory and is poured in directly.
