    • According to this method, exhaust fumes from an engine of a marine vessel enter the lower part of a scrubber (100) and flow upward inside the scrubber. The fumes flowing in the scrubber are distributed substantially homogeneously over the cross-section of the scrubber (100) by a distributing device (400), which is arranged inside the scrubber and which includes a body (401) provided with perforations (402) connecting an upper face (401A) of the body, which is inclined relative to the horizontal, and a lower face (401B) of the body, which is reached by the fumes rising in the scrubber from the lower part of the scrubber. Water is spread inside the scrubber (100) in the form of a rain (P), which falls toward the bottom of the scrubber onto the upper face (401A) of the body (401) and which, once it has fallen in the upper face of the body, streams there while forming a water film (F) covering the upper face of the body, including at least partially the upper mouth of the perforations (402) of the body. The fumes flowing in the scrubber (100) flow in the perforations (402) of the body (401) with a velocity of between 5 and 25 m/s when the average velocity of these fumes upstream and downstream from the body is between 3 and 7 m/s, such that the flow of the fumes in the perforations prevents the water of the water film (F) from flowing in the perforations and the meeting between the flow of the fumes leaving the perforations and the water of the water film streaming over the upper face (401A) of the body from generating jets (J) sprayed above the body from the upper face of the body.
