Abstract

Urea granulation process with scrubbing system including at least one gaseous waste stream for removal of dust and ammonia whereby this waste stream is processed through a combination of the following process steps comprising (a) washing the dust and ammonia laden stream (4) with water and/or an aqueous urea solution whereby a dust- laden liquid stream (26) and a dust- reduced stream (5) is generated ,and (b) reacting the dust -reduced stream (5) with formaldeyhde (7) to form a stream (8) comprising hexamethylenetetramine and urea- formaldehyde and clean off -gas (6) wherein the gas stream is directed first through process step (a) and then through process step (b).
