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
