Question

How is ammonia separated from unreacted nitrogen and hydrogen?

Answer 1

Hello mate,

Here is your answer,

------------------------------------------------------------------------------------------------

The reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen.

The mixture is cooled and compressed, causing the ammonia gas to condense into a liquid.

The liquefied ammonia is separated and removed. The unreacted nitrogen and hydrogen are then recycled back into the reactor .

------------------------------------------------------------------------------------------------------

HOPE THIS HELPS UU :)

AND STAY BLESSED.

Answer 2

Ammonia separation from unreacted nitrogen and hydrogen

• The NH3 is a condensable gas. when it is cooled the vapours get added to the liquid. And the non-condensable gas does not get condensed when they are cooled.

• Ammonia is produced by the Haber process which is an exothermic reaction; meaning heat leaves the system; Ammonia is a heavy gas which is made up of heavier molecules so it will get condensed while cooling.

• When Ammonia gets condensed nitrogen and hydrogen are in liquid form so it is easy to separate them. Then the unreacted gases are recycled back.

• So the easiest process to get unreacted hydrogen and nitrogen is to get the ammonia cooled
