Why is it necessary to remove impurities such as calcium and magnesium ions from sodium chloride solutions?
Since impurities such as calcium and magnesium ions can form calcium carbonate, magnesium hydroxide, magnesium carbonate, and other insoluble complex salts during the ammoniated carbonation process, thereby blocking equipment and pipes and affecting heat transfer and the quality of the final product, these impurities must be removed before they reach the Tasco facility.

Since impurities such as calcium ions and magnesium ions generate calcium carbonate, magnesium hydroxide, magnesium carbonate, and other insoluble complex salts during the ammoniated carbonation process, which can clog equipment and pipes and affect heat transfer as well as the quality of the final product, these impurities must be removed from the ammonium chloride solution before it enters the ammonia absorption tower.
Since impurity ions such as calcium and magnesium generate calcium carbonate, magnesium hydroxide, magnesium carbonate, and other insoluble complex salts during the ammoniated carbonation process, which can clog equipment and pipes and affect heat transfer and crystal quality, these impurities must be removed from the sodium chloride solution before it enters the ammonia absorption tower.

Answer: Impurities such as calcium and magnesium ions, during the ammoniation and carbonation processes, form calcium carbonate, magnesium hydroxide, magnesium carbonate, and other insoluble complex salts, which can clog equipment and pipes and affect heat transfer as well as the quality of the final product; therefore, these impurities must be removed before they reach the ammonia absorption tower. 1# chen3jun
Since impurities such as calcium and magnesium ions can, during the ammoniated carbonation process, form CaCO3, Mg(OH)2, MgCO3, and other insoluble complex salts that clog equipment and pipes and affect heat transfer as well as the quality of the final product, it is necessary to remove these impurities from the sodium chloride solution before it enters the ammonia absorption tower.
2. Because impurities such as calcium ions and magnesium ions can form CaCO3, Mg(OH)2, MgCO3, and other insoluble complex salts during the ammoniated acidification process, these substances can clog pipes and equipment and affect heat transfer as well as product quality; therefore, these impurities must also be removed from sodium chloride before it enters the ammonia tower
Since impurities such as Ca2+ and Mg2+ will form CaCO3, Mg(OH)2, MgCO3, and other insoluble complex salts during the ammoniated carbonation process, thereby blocking equipment and pipelines and affecting heat transfer and the quality of the final product, these impurities must be removed from the sodium chloride solution before it enters the ammonia absorption tower.
Answer: Impurities such as calcium ions and magnesium ions cause the formation of calcium carbonate, magnesium hydroxide, magnesium carbonate, and other insoluble complexes during the ammoniated carbonation process; these substances clog pipes and equipment, affecting heat transfer and the quality of the final product. Therefore, these impurities must be removed from the sodium chloride solution before it enters the ammonia absorption tower.
