NOVELTY - Removing (M1) urea dust from off-gas (2) of a finishing section (1) of a urea production plant, comprises: subjecting the off-gas to quenching with water (6) to lower a temperature of the gas stream by more than 50 degrees C for producing quenched off-gas having a temperature of less than 45 degrees C; and subjecting the quenched off-gas to scrubbing using at least one venturi scrubber (11).    USE - The method is useful for removing urea dust from off-gas of a finishing section of a urea production plant.    ADVANTAGE - The method: facilitates efficient removal of urea dust, and growth of urea particles, as compared to conventional methods; can be performed in a simple, cost effective and environmental friendly manner; and reduces energy consumption.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a finishing equipment for a urea plant, comprising a urea finishing device that comprises an inlet for liquid urea, an inlet for cooling gas, a collector for solid urea, an outlet for off-gas and the venturi scrubber, where the outlet for off-gas is in fluid communication with the venturi scrubber, and a quenching system is installed between the urea finishing device and the venturi scrubber;    (2) the urea plant comprising a synthesis and recovery section, where: the section is in fluid communication with an evaporation section; the evaporation section is in fluid communication with a finishing section and has a gas flow line to a condensation section; and the finishing section has a gas flow line to a dust scrubbing section, and comprises the finishing equipment; and    (3) modifying (M2) an existing urea plant comprising the synthesis and recovery section that is in fluid communication with the evaporation section (where the evaporation section is in fluid communication with the finishing section and has a gas flow line to the condensation section, the finishing section has a gas flow line to the dust scrubbing section, and the dust scrubbing section is provided with the venturi scrubber), comprising installing the quenching system between the finishing section and the venturi scrubber, where the quenching system is in fluid communication with the gas flow line between the finishing section and the dust scrubbing section.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the dust scrubbing system.    Finishing section (1)    Off-gas (2)    Duct (3)    Water (6)    Venturi scrubber (11)
