Haber process

The process was invented by Fritz Haber and Carl Bosch. It is used to produce fertilizer by fixing atmospheric nitrogen. The catalyzed reaction converts nitrogen (N2) and hydrogen (H2) into ammonia (NH3) under high temperature/pressure conditions.

The set up of ammonia production. Two gases - nitrogen and hydrogen flow into the reaction chamber with the catalyst, where they are turned into ammonia. The product of the reaction, together with residual reactants flow into the condenser with the cooling system, where ammonia is liquified and removed from the system, whereas residual nitrogen and hydrogen are recirculated back to the system.
