For nitrogen-based fertilizers, the largest product group, the process starts bymixing nitrogen from the air with hydrogen from natural gas at high temperature and pressure to create ammonia. Approximately 60% of the natural gas is used as raw material, with the remainder employed to power the synthesis process.

How is nitrogen fertilizer made?
In a modern plant, nitrogen fertilizer is produced from natural gas. In several transformation steps, natural gas, essentially methane, is upgraded by combination with nitrogen from the air to form nitrogen fertilizer. 80% of the gas is used as feedstock for fertilizer while 20% is used for heating the process and producing electricity.
What is natural gas used for in fertilizer production?
Approximately 60% of the natural gas is used as raw material, with the remainder employed to power the synthesis process. The ammonia is used to make nitric acid, with which it is then mixed to produce nitrate fertilizers such as ammonium nitrate (AN).
What are the raw materials of fertilizers?
Primary fertilizers include substances derived from nitrogen, phosphorus, and potassium. Various raw materials are used to produce these compounds. … When ammonia is used as the nitrogen source in a fertilizer, one method of synthetic production requires the use of natural gas and air.
