Beschreibung
Zusammenfassung:	The invention relates to a gas-liquid separation device, in particular for use in the recirculation zone of three-phase fluidised bed reactors. The gas-liquid separation device comprises a plurality of separation elements, each having an inlet duct (70) and a succession of at least two bends (71, 72), a first bend (71) located in the plane (zy), the axis of the first bend (71) forming an orientation angle a relative to the vertical axis z of between 45° and 315°, and a second bend (72) forming a second orientation angle p with the first bend (71) of between 1° and 135°. The two first successive bends (71, 72) are separated by a distance D1 of between D/2 and 4D, D being the diameter of the inlet duct (70). Each separation element comprises a liquid guidance device (73) which is positioned at the outlet end of the second bend (72), and which has an open section.
