Harber Process

• Haber Process Overview

  A chemical process for producing ammonia from nitrogen and hydrogen, using an iron catalyst at high temperature and pressure.
• Balanced Chemical Equation

  $N_2(g) +$$3H_2(g) \leftrightarrow 2NH_3(g)$
• Conditions for the Reaction(Harber Process)

  Optimal conditions include a temperature of approximately 450-500°C, a pressure of around 200 atm, and the presence of an iron catalyst
• Temperature Compromise

  Although lower temperatures would shift the equilibrium toward ammonia production, higher temperatures are used to increase the reaction rate. This is a compromise for efficiency.
• Ammonia Purification

  Ammonia is separated from unreacted hydrogen and nitrogen by cooling the gas mixture; ammonia liquefies and can be removed, while the gases are recycled back into the reactor. Increasing the yield of Ammonia.
