Urea is one of the oldest industrial products. The anhydrous ammonia manufacturing process used by different companies, including IFFCO, has been around for close to a century. The different production technologies are all variants of the process developed in the 1900s.
Proven, well-known process
The primary raw materials used in the process are natural gas, electricity, water and air.
The commercial production of urea requires the use of pressurized ammonia and carbon dioxide in a multistage process in two separate production facilities, an ammonia unit and a urea unit.
Ammonia is produced when nitrogen present in the air reacts with the hydrogen present in natural gas. This stage generates carbon dioxide which is used in its entirety for urea production in the second unit. The urea is then dried in the granular form or mixed with water to form liquid urea or diesel exhaust fluid (DEF).
