Urea
PT. Iskandar Muda fertilizer produces two types of urea, namely Prilled Urea and Granular Urea.
The technical specification of those two kinds of urea is relatively the same, only different in terms of grain size where the urea granules are larger and contain more anti cacking.
| Technical Specification | Prilled Urea | Urea Granule |
|---|---|---|
| Nitrogen content | 46 % (Minimal) | 46 % (Minimal) |
| Water content | 0,5 % (Maximal) | 0,5 % (Maximal) |
| Biuret | 1,0 % (Maximal) | 1,0 % (Maximal) |
| Color | White (coated and uncoated) | White with anti cacking treatment |
| Packaging | In 50-kg sacks and bulk | In 50-kg sacks and bulk |
Apart from its use as fertilizer, urea can also be used as raw materials for Melamine, Urea Formaldehyde and Acrylate Plastic productions.
Urea Process
Urea is formed from chemical reaction between ammonia (NH3) and carbon dioxide (CO2). Pure urea solution is crystallized in a vacuum, and then melted back into melter by using steam as the heater. From the upper prilling tower, molten urea is then applied dropwise and will be condensed after cooled with air.
