Abstract (en)
[origin: WO8701759A1] A device for gathering liquid slugs in a pipeline transporting gas (slug-catcher), particularly in the context of the recovery of offshore oil and gas deposits. The pipeline leads along the seabed to an intake unit above the water usually a platform. The pipeline also is linked to a secondary riser (14) which has a smaller cross-section than the cross-section of the main pipeline (12). The main pipeline (12) leads to a loop (15) along the seabed from the junction so that the length is sufficient to accommodate a slug and retard it. The riser (14) is equipped with a regulatory throttle (22) which can provide counter-pressure to empty liquid into the main pipeline.
