Urea - Import export

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.

Hamon Research-Cottrell provides process and equipment expertise, drawn from more than fifteen years of experience with the patented Urea to Ammonia U2A® technology, starting from bench and pilot scale, through systems for small gas turbine SCR and the largest utility scale SCR systems for coal and gas fired boilers.Hamon Research-Cottrell’s U2A® system provides several benefits:Urea as feedstock eliminates the hazards associated with the transport, transfer and storage of toxic anhydrous or aqueous ammonia.Compared with using 19% aqueous ammonia, energy use is reduced.Process control response provides ammonia on demand, easily following load conditions.Hamon Research-Cottrell offers U2A® on a worldwide basis and has installations in Europe and the Middle East in addition to a large installed base in the United States.
