12% ammonia solution concentrated to 20%
Thread Content
Has anyone considered concentrating ammonia solution with a concentration of around 12% to 20%? Currently, low-concentration ammonia solutions are hard to sell, while ammonia solutions with a concentration of over 18% have a good market demand. The synthetic purge gas has a pressure of 10 MPA; existing membrane recovery units are in use, and the ammonia concentration in the high-pressure ammonia washing tower is around 12%. How to concentrate?
Ammonia vapor is extracted through an ammonia distillation tower, which allows for concentration as well as the production of liquid ammonia.
It is still necessary to choose an appropriate use based on the ammonia concentration; evaporating ammonia to concentrate it is not economical.
Build your own ammonia absorber; if you sell ammonia solution, you don’t need to use it, but you can operate an ammonia vaporization system.

The steam consumption for concentrating 12% ammonia solution is approximately 145 kg per ton of wastewater; you can calculate the economic aspects. It is more economical if used as ammonia water for desulfurization and denitration.
Using a high-position ammonia absorber to absorb gaseous ammonia for concentration is the simplest method
Producing 20% ammonia solution by mixing ammonia and ammonia water might be more economical
