Abstract:
Disclosed is a method for the removal of urea dust from the off-gas of a finishing section (1) of a urea production plant, the method comprises subjecting the off-gas to quenching with water (06) so as to produce quenched off-gas, and subjecting the quenched off-gas to scrubbing using at least one venturi scrubber (11). As a result, a lower pressure drop over the scrubber is attained, and a more efficient growth of urea particles, facilitating the removal thereof.
