UREA – Defined
Urea is a white dry organic compound and a crystalline substance and has minimum of 46% Nitrogen calculated in dry state. This has the melting point of 132 deg F.
CHEMICAL FORMULA FOR UREA:
CO(NH2)2 or NH2CONH2
HOW IS UREA MADE?
Urea is made by reacting carbon dioxide (CO2) with anhydrous ammonia (NH3) under pressure of 3000 psi and temperatures of around 350 deg F. Water is removed during processing and the molten matter is either converted to prills or into granules.
SHAPE OF UREA:
It is generally supplied in prills or crystals/grains. Although the colour of urea is white but the crystals are larger than prills.
