The present invention relates to a device (20) located near to the point of junction of a multiphase-stream underwater flow line (5) with a stratified phase pattern, and an underwater riser (4), which introduces a pressure drop into the flow and causes a vigorous mixing effect, temporarily converting this flow into a non-stratified pattern of flow, such as an annular stream, thereby preventing the establishment of the phenomenon of severe slugging.
Cette invention concerne un dispositif (20) situé près du point de jonction d'une conduite d'écoulement multiphasique immergée (5) munie d'un diagramme de phase stratifié et d'une colonne montante immergée (4). Le dispositif inflige à l'écoulement une chute de pression provoquant un brassage énergique qui permet temporairement de transformer cet écoulement en un diagramme non stratifié, tel qu'un écoulement annulaire, ce qui empêche le phénomène de bouillonnage violent.
