UREA

UREA is a white dry organic compound and a crystalline substance and has minimum of 46% Nitrogen calculated in dry state, and has the melting point of 132 deg F.

UREA is made by reacting carbon dioxide (CO2) with anhydrous ammonia (NH3) under pressure of 3000 psi and temperature of around 350 deg F. water is removed during processing and the molten matter is either converted to prills  or into granules

Its generally supplied in prills or crystals/ grains. Although the color of urea is white but the crystals are larger then prills

UREA has the highest nitrogen content of all solid nitrogenous fertilizer. Urea is produced in excess of 140.000.000 tons per year world wide, of which more than 90% of world production destined for use as fertilizer

Solid Urea is marketed as prills or granules. The advantage of prills is that I general then can be produced more cheaply than granules, which, because of their narrower  particle size distribution have an advantage over prills if applied mechanically to the soil. Properties such as impact strength. Crushing strength and free- flowing behavior are particularly important in product handling, storage and bulk transportation.

Industrial Use

UREA'S commercial uses included

-          As a component of fertilizer and animal feed, providing a relatively cheap source f fixed nitrogen to promote growth

-          As a raw material for manufacture of plastic specifically, Urea- formaldehyde resin

-          As a raw material for the manufacture of various glues( Urea- formaldehyde or Urea- melamine-formaldehyde). The latter is waterproof and is used for marine plywood

-          As an alternative to rock salt in the deicing of roadways and runways, it does not promote metal corrosion to the extent that salt does

-          As an additive ingredient in cigarettes, designed to enhance flavor

-          Sometimes used as a browning agent in factory- produced pretzels

-          As an ingredient in some hair conditioners, facial cleansers, bath oils and lotions

-          Its also used as a reactant in some ready-to-use cold compresses for first-aid use, due to the endohermic  reaction it creates when mixed with water

-          Active ingredient for diesel engine exhaust treatment AdBlue and some other SCR systems

-          Used, along with salts, as a cloud seeding agent to expedite the condensation of water in clouds, producing precipitation

-          The ability of Urea to form clathrates( also called"loose compunds" host-guest complexes, inclusion compounds, and adducts) was used in the past to separate paraffin's

-          As a flame-proofing agent

-          As a clean burning fuel for motor vehicles and stationary engines

-          As a NOx-reducing reactant indiesel exhaust
