A device for inhibiting severe slug flow in a multiphase fluid stream flowing through a pipeline and into a riser, wherein, the device is positioned immediately upstream of the riser and comprises at least one unit comprising (i) an upwardly inclined section of pipe having a lower end and an upper end and (ii) either a substantially horizontal section of pipe having a first end and a second end or a downwardly inclined section of pipe having an upper end and a lower end, wherein the lower end of the upwardly inclined section of pipe is connected either directly or indirectly with the pipeline, the upper end of the upwardly inclined section of pipe is connected either directly or indirectly with the first end of the horizontal section of pipe or with the upper end of the downwardly inclined section of pipe, and the second end of the horizontal section of pipe or the lower end of the downwardly inclined section of pipe is connected either directly or indirectly with the riser, and wherein the angle of inclination of the upwardly inclined section of pipe is in the range 5 to 90° to the horizontal, and the length of the upwardly inclined section of pipe is in the range 1 to 30 feet. |
