Urea Quality and Properties
Urea is created from synthetic ammonia and carbon dioxide when subjected to high heat and pressure and can be produced as a liquid or solid. The chemical formula for urea is NH2CONH2. Ninety percent of urea is used as fertilizer with other applications including NOx reduction, plastics, animal feed, cleaning agents, and pharmaceutical applications.The concentrations or strengths we supply are 70%, 50%, 40% and 32.5% with or without Fuel Tech NOxOUT Urea Solution, as well as dry granular and prilled Urea.
The typical properties are:
|Urea Strength (+/- 1%)||32.5||40||50|
|Free Ammonia (at loading)||<0.3%||<0.3%||<0.5%|
|Biuret (at loading)||<0.5%||<0.5%||<0.5%|
|Magnesium (Mg)||<.08 ppm||<.08 ppm||<.08 ppm|
|Calcium (Ca)||<.08 ppm||<.08 ppm||<.08 ppm|

Storage and Delivery
Urea Storage Tanks
Vertical, atmospheric tanks are appropriate for storing urea solution and are typically sized from 6,000 gallons to 30,000 gallons. Tank heating and insulation are required to maintain the urea solution above the salt-out temperature. The tank should provide temperature and level indications. Colonial can furnish a telemetry system which provides an effective, low cost means of monitoring the urea inventory and ensuring deliveries are made at the right time with minimal customer effort.
Recommended Materials of Construction: Stainless Steel, Polyethylene, Polypropylene, PFA, PFE, PVDF, PTFE (free of additives)
Bulk deliveries of Colonial urea solution are made in dedicated stainless steel insulated tank trucks. The urea is discharged through the mid or rear tank bottom and a flexible hose usually 20 to 40 feet long. Our trucks vary in dimensions but typically a tractor and trailer are 65 feet long, 8 feet wide with a turning radius of 200 feet.
Capacity: 5,000 gallons / 23 to 24 tons
Gross weight: 40 tons
