How to reduce moisture in liquid ammonia
Thread Content
The original moisture content in liquid ammonia was around 1%, and it needs to be reduced to below 0.5%. Are there any good process methods for this?
If the production volume is high, distillation with a tower can be used for dehydration; if the amount is small, metal salts can be used for dehydration.
Could you elaborate on which metal salts to use? Is it necessary to use a tower for such concentrations, and what are the costs involved?
