Socrematic WATTRAY - Tray Scrubber for Urea Dust Removal
The WATTRAY tray scrubber, developed by SOCREMATIC, is an advanced air treatment solution specifically designed for dust removal applications in the fertilizer industry. This scrubber employs fixed valve trays that combine attributes of traditional trays with movable valves and sieve trays, ensuring robust resistance to soiling and superior separation efficiency. The WATTRAY scrubber is equipped with multiple layer WATMESH bone crimp demisters that enhance its demisting functionality. Particularly effective at removing urea dust particles, it operates as a vertical crosscurrent gas-liquid contactor. The device facilitates intimate contact between gas phases containing urea dust and an aqueous urea solution within the scrubber's multiple tray system. Gas enters from the bottom and moves upwards, while the UAS (Urea + Ammonium Sulphate) solution flows downward, enabling efficient dust removal from off-gas emissions, such as those from fluidized bed granulators.
The WATTRAY® scrubber is SOCREMATIC’s tray scrubber technology using fixed valve trays in combination with multiple layer WATMESH® bone crimp demisters and is particularly adapted for :
- Urea dust removal in exhaust of fluidized bed urea granulation plants
- Calcium ammonium nitrate fluidized bed exhaust
- Urea and ammonium nitrate prilling tower exhaust
The fixed valve tray is a combination of the characteristics of a tray with movable valves and a sieve tray. In addition to its high resistance to soiling, the SOCREMATIC WATTRAY® scrubber is characterized by its high capacity and separating efficiency
Fixed valve tray gas-liquid contactor
Dedicated to urea dust removal, the WATTRAY® scrubber will be typically installed as to reduce the urea dust particles remaining in the off-gas from the fluidized bed granulator, final cooler exhausts off gas.
This technology consists in a vertical crosscurrent gas-liquid contactor containing two Fixed Valve Tray type. The said trays provide the intimate contact between the gas phase containing urea dust particles and the aqueous urea diluted recovered solution.
The recirculated UAS (Urea + Ammonium Sulphate) solution enters the WATTRAY® scrubber at the top of the urea section and flows downward by gravity.
On its way, it flows horizontally across from top tray through a down comer to the tray below while the gas flow enters crosscurrent the scrubber at the bottom and is directed upwards through the openings provided by the valve trays.
