  • Device and method for eliminating severe slugging in multiphase-stream flow lines
    Patent number: 6041803
    Abstract: The present invention relates to a device located near to the point of junction of a multiphase-stream underwater flow line with a stratified phase pattern, and an underwater riser, 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.
