In the carbonation process of the ammonia-soda method, ( ) and ( ) are two important process parameters. 7. As the temperature increases, the sodium utilization rate ( ). 8. As the temperature for carbonation removal increases, the NH3 and NaCl concentrations of the ammonium salts required to reach point P1 are ( ). 9. When the concentration of the ammonia salt solution remains constant, the higher the temperature at the carbonation outlet, the greater the resulting value; therefore, when the carbonation mother liquor is not cooled sufficiently, it will lead to (). 10. The sodium chloride solution used in the ammonia-alkali process can be ( ), or it can be ( ).
6. Sodium utilization rate, ammonia utilization rate 7. Increase 8. Increase regularly 9. The lower the sodium utilization rate; a decrease in the sodium utilization rate 10. Brine obtained directly from salt wells, with solid table salt dissolved to create it
6. During the carbonation process in the ammonia-alkali method, (sodium utilization rate) and (ammonia utilization rate) are two important process parameters. 7. As the temperature increases, sodium utilization improves. 8. As the temperature for carbonation removal increases, the NH3 and NaCl concentrations of the ammonium salt required to reach point P1 increase (in a regular manner). 9. When the concentration of the ammonia salt solution remains constant, the higher the temperature at the carbonation outlet, the lower the sodium utilization rate. Therefore, insufficient cooling of the carbonation mother liquor leads to a decrease in sodium utilization rate. 10. The sodium chloride solution used in the ammonia-alkali process can be (brine obtained directly from salt wells), or it can be (prepared by dissolving solid table salt).
6. Sodium utilization rate, ammonia utilization rate； 7. Improve ； 8. Regular increase ； 9. The lower the sodium utilization rate, the greater the decrease in this rate ； 10. Brine obtained directly from seawater, made by dissolving solid table salt.
