The process of producing granular urea fertilizer is such that ammonia and carbon dioxide gas after compression are transferred to the urea synthesis unit and in this unit ammonia and carbon dioxide are converted to urea under certain temperature and pressure conditions and after evaporation and purification The urea is transferred to the granulation unit and the final product of urea fertilizer in this unit is solid granulated and granulated. Granular urea fertilizer is white and in the size of 2 to 4 mm, which has a larger grain size than Peril urea fertilizer. Both granule and peril urea fertilizers are almost identical in chemical properties and contain 46% nitrogen. It should be noted that the grain strength in the granule model is higher than the peril model.
Due to the similar effect of granular urea and peril fertilizer in the agricultural sector, it seems that each of these two models is more popular in different regions due to the presence of more of that sample in that market and has a somewhat psychological aspect.
Nitrogen chemical fertilizers, of which 46% urea is one of the types, has played a very important role in increasing world food production in the last half century, and according to some statistics, it accounts for about 60% of global chemical fertilizer consumption. Is . Nitrogen is one of the most important nutrients needed by crops and orchards and according to some theories after water is the most important factor limiting plant growth. Urea, which has the highest amount of nitrogen (46%) among solid nitrogen fertilizers, is produced and marketed in two samples of granules and perils.
