ANORDNUNG VON PIPELINES, UM WENIGSTENS EIN ZWEIPHASIGES FLUIDGEMISCH ZU TRENNEN

An integrated system for separation of gas, from a two-phase flow of oil and gas, in a secondary riser. The oil and gas is transported in a pipeline (1), e.g. from an oil well, at the seabed and by risers (2, 3) onto the platform. The main riser (2) for transporting oil is connected to an oil storin...

Zusammenfassung:	An integrated system for separation of gas, from a two-phase flow of oil and gas, in a secondary riser. The oil and gas is transported in a pipeline (1), e.g. from an oil well, at the seabed and by risers (2, 3) onto the platform. The main riser (2) for transporting oil is connected to an oil storing tank (4) situated on the platform. The secondary riser is connected via a T-junction (5) to the pipeline (1) at a distance (X) from the main riser and leads to a gas scrubber (6) on the platform. The secondary riser contains a regulating valve which is operated by controlled means in such a way as to keep the interface between the gas and the oil at a relatively constant location in the pipeline between the T-junction and the main riser. The section of the pipeline (1) between the T-junction (5) and the main riser (2) incorporates sensors for detecting the proximity of the interface.
