Highlights of UFT fluid bed granulation process

The key features of the UFT fluid bed granulation process are:

• Technology proven over more than 25 years
• Excellent product quality; word-wide distributed and honored
• Single-stream capacities matching with largest urea synthesis units developed to date
• Flexibility in end product size, ranging from 2 to 7 mm average diameter
• Highest on-stream factor
• 96% urea solution feedstock results in:
  • low biuret in final product
  • low investment cost, only single stage evaporation unit required
  • less cooling air required in granulation process due to utilization of water evaporation for cooling during crystallization of 96% urea melt
• Low operating cost
  • less steam and cooling water consumption for concentration of urea to 96% only
  • less power required for air handling in granulation due to utilization of water evaporation for removing of heat of crystallisation
• High operating flexibility, even down to 10 % of the nominal capacity
• Efficient control of the atmospheric emissions, compatible with the most stringent environmental laws
  • Urea dust abatement through standard, commercially available, wet scrubbing systems
  • Mild ammonia abatement by means of formaldehyde injection into granulator exhaust air
  • Deep ammonia abatement by means of acidic scrubbing
• Maximum use of gravity flow as inside battery limit means of transport
