1. A method for decanting oil contained in a gas stream by means of a device, the method providing for: circulating the gas stream containing oil to be separated between an inlet area and an outlet area of the device; arranging at least one intermediate area provided with at least one filter element for capturing drops of oil contained in the gas stream; and creating at least one calm area in which the oil is collected and discharged, after having been captured, the at least one calm area being subjected to a vacuum through a communication channel arranged between the at least one calm area and the outlet area, the device comprising a separation wall arranged to separate the at least one calm area from the or each intermediate area, wherein the gas stream is passed in contact with at least one porous medium, one face of which is in communication with the calm area, in such a manner that oil drops are captured by the porous medium and are suctioned through the porous medium to arrive in said calm area, and wherein the or each intermediate area defines at least one main gas stream passage configured for the flow of a main gas stream, and said at least one filter element defines at least one secondary gas stream passage configured for the flow of a secondary gas stream from the or each intermediate area towards said calm area, said at least one main gas stream passage being separate from said at least one secondary gas stream passage.
