Urea scrubbers

The air from  the  Granulators  and  the  Coolers  contains urea dust that is entrapped in Hamon’s scrubbers. In these industrially  proven  impact  type  scrubbers,  efficiencies  are very  high  and  dust  concentrations  lower  than  20  mg/Nm3 can be achieved at the stack outlet. The total amount of urea collected by these scrubbers is recycled, for reconcentration, to the process.

The same process is used to capture NH3 from the gases at the outlet of the Fertilizer Industry.
