Synthetic Ammonia Process Technology Exchange Area [Daily Question 2009-02-26] What is the acceptable range for the total alkali level in the double dehydration unit? What is the stable temperature range of the lean liquid in the double-dehydration unit? This post was last edited by jindin312 on 2009-2-27 19:56.]
Generally, the ammonia concentration is kept between 180 and 210 titers. Generally, the temperature of the lean liquid is controlled between 60 and 70 degrees Celsius.
Alkalinity: 0.4–0.6 mol/l; temperature of the lean solution: 38–42 degrees.

Total alkalinity after first desalination: 0.4–0.5; after second desalination: 0.6–0.7. Temperature of the depleted liquid: 38–45°C, and not less than 35°C in winter ℃
First desalination: total alkalinity of 0.5–0.6; second desalination: 0.6–0.7. Temperature of the depleted liquid: 35–45°C.
Total alkalinity: 0.4–0.6; Temperature of lean solution: 35–45℃
