Urea

It is an organic compound produced by the reaction of ammonia and carbon dioxide at high pressure to produce an intermediate compound called ammonium carbamate, which decomposes to produce urea in liquid form. The concentration of the urea solution is gradually increased inside the units by separating and recycling the unconverted reactants and evaporating the water content to reach a concentration of 96%, which is directed to the granulation unit to produce granulated urea. Ammonia and carbon dioxide are supplied from the ammonia plant, and more than 90% of the world's urea production is directed to the field of fertilizers as a source of nitrogen, as urea contains the highest nitrogen rate among all solid fertilizers, with a nitrogen percentage of 46.6.
