Method for liquid control in multiphase fluid pipelines

A method for the control of liquid or liquid slugs in multi phase fluid pipelines, including a multiphase pipeline (1) for the transportation of a fluid, consisting of mainly gas and some liquid such as water an/or gas condensate. The gas is evacuated via a gas separation unit (4) being connected to the multiphase pipeline (1) to a second gas transport pipe (5), whereas the liquid is fed to a dedicated pipeline section acting as a buffer volume pipeline (7), preferably provided as a continued part of the multiphase pipeline (1). The separation unit (4) includes one or preferably several vertical pipes (6) connected at a distance from one another along the multiphase pipeline (1), whereby the gas is transported separately to a downstream processing facility on a platform or onshore (3) or the like, and whereby the liquid proceeds to the loop (7) which may preferably be an extension of the multiphase pipeline, or the liquid and gas may be re-combined and led in a common transport pipeline to the desired destination.
