Caption: Ammonia production. Schematic diagram of the Haber Process to make ammonia (NH3) from nitrogen (N2) and hydrogen (H2) gas. Hydrogen (red) and nitrogen (blue) are first cleaned (lower left), mixed, and then compressed (centre left, 200 atmospheres). The mixture cycles through the reaction tower (right) and a catalyst (iron, on horizontal trays) and heat (450 degrees Celsius) form ammonia. A cooling loop (water, pale blue) at the base of the reaction tower condenses the ammonia into a liquid (orange) that is piped off at lower right. Ammonia is widely used in the chemical industry to produce other chemicals, particularly fertilisers, and the process seen here is an important method of fixing nitrogen from the atmosphere.
