How to separate ammonia and nitrogen

How are ammonia and nitrogen separated? Urgently needed
Using chemical methods, acid washing followed by alkali washing, to remove ammonia gas. . . . . . . . . . . . . . . . . . . . . .
Thank you! ! ! Are there any physical methods? Like high-pressure liquefaction for ammonia recovery, something like that? Do you have technology for the recovery of ammonia from high-pressure liquefied form?
Nitrogen can be obtained by first washing with hydrochloric acid; ammonia can be obtained by adding sodium hydroxide to the acid-washed solution and heating it
This seems to be a rather specialized area; it can be detected using professional gas analyzers. I’m not really sure about the specific methods for separation
The ammonia recovery in the ammonia synthesis plant can fully meet your requirements.
Do you have more ammonia or nitrogen? What is its composition? I’ll simply provide you with the separation method: there is more ammonia and less nitrogen, so separation seems unnecessary; if separation is really required, compress and cool to recover the ammonia ； If there is more nitrogen and less ammonia, the ammonia can be removed through acid washing; the decision depends on which gas you want to obtain, with separation being determined based on overall costs. If there is the same amount of ammonia as nitrogen, if you want to recover ammonia, it’s better to do so through compression and cooling; if you don’t intend to recover it, then acid washing will suffice. It seems unnecessary to recover nitrogen, haha~
Hehe, what comes out using your method is probably not ammonia, but air with a slight ammonia smell.
Wash with water, or cool down to the condensation point of ammonia to turn it into a liquid and then separate it
