The main purpose of primary refining of brine is to control the content of suspended solids (SS) and various impurity ions within the required range to prepare for secondary refining of brine. The most important part of the secondary refining of brine is the chelating resin tower, which removes divalent cations from the crude brine after passing through the resin tower.
1. Improve the quality of soda ash products and reduce the incompatible substances CaCO3 and MgCO3 in soda ash products.； 2. Reduce scarring on towers and pipes during the ammonia absorption process ； 3. Reduce the loss of ammonia, salt and carbon dioxide during the production process.
