BEGG COUSLAND ENVIROTEC LTD. Ammonium Nitrate Granulator Dryer Emission Control The Becoflex system comprises a fan type volute containing a rotating brush, a brush spraying system and this is then connected to a discharge vessel, where the liquid / slurry is collected in the sump and drained or recirculated, while the cleaned air exits through the top section. The key features of the Becoflex technology are : ¾ Highly effective gas scrubbing by means of dynamic contact between gas and liquid resulting from the rotating brush fibres ¾ Solids removal and self-cleaning by the liquid scrubbing action and centrifugal slurry discharge ¾ Air movement by suction generated by the rotating brush, more than needed for the system resistance, making it free of pressure loss. ¾ Minimisation of scrubbing liquid volume due to the intensive contact within the fan volute ; liquids can also be recirculated ¾ Minimisation of the scrubber size and footprint ¾ Mimimum maintenance requirement Becoflex Rotary Brush Scrubber Case Study www.beggcousland.

BEGG COUSLAND ENVITOTEC LTD. Pilot units tests were done in Europe on the exit air flow of an Ammonium Nitrate Granulator Dryer to achieve emissions of less than 10mg/Nm3. The results were less than 10mg/Nm3 and a first order was placed for a full scale installation handling up to 65,000 Nm3/hr. Design : Combined Total Air Flow : 64,000 m³/Hr (maximum) using : A flow of 17,000 to 25,000 m³/Hr per each of 2 x Becoflex BF130 Rotary Brush units A flow of 7,000 to 15,000 m³/Hr per each of 2 x Becoflex BF114 Rotary Brush units All 4 Becoflex Brush sections discharge into the same collector duct leading...
