Abstract: The current disclosure relates to multiphase fluid separation via a multiphase separation system. The multiphase separation system is configured to feed a multiphase fluid into an inlet line within the separation system. The multiphase fluid is configured to flow through a divide and be split into separate lines of similar diameter. A control volume is also connected at the end of the separate lines, and the control volume has a diameter greater than the separate lines of similar diameter. The control volume includes outlet lines, and is configured to adjust fluid flow rate at an outlet line. Also included in the current disclosure is a sand boot connected to the separate lines that is oriented vertically with respect to the separate lines, and is configured to collect and remove sand accumulated in the multiphase separation system.

Abstract: The current disclosure relates to multiphase fluid separation via a multiphase separation system. The multiphase separation system is configured to feed a multiphase fluid into feed lines within the multiphase separation system, wherein the feed lines consist of an upper line, a middle line, and a lower line. The upper line is configured to flow a first stream substantially including oil into an oil section of a control volume. The middle line is configured to flow a second stream substantially including an oil/water emulsion into an oil/water emulsion section of the control volume. The lower line is configured to flow a third stream substantially including water into a water section of the control volume. The control volume is configured to adjust fluid flow rate at an outlet, wherein the oil section, the water section, and the oil/water emulsion section each commingle at different heights of the control volume.

Abstract: Embodiments described herein provide a system and methods for separating oil and water streams. The method includes separating a fluid stream into an oil continuous stream and a water continuous stream using a cyclonic separator, flowing the oil continuous stream to a first gravity separation vessel, and flowing the water continuous stream to a second gravity separation vessel. The method also includes separating the oil continuous stream in the first gravity separation vessel into an oil stream and a water stream and separating the water continuous stream in the second gravity separation vessel into an oil stream and a water stream.
