A slug mitigation system for subsea pipelines includes a riser located between a low level and an upper (above sea-) level of a pipeline, where an inline separator, e.g. an 'I-SEP', is located upstream of a first stage separator. A throttling valve or fixed restriction is located downstream or upstream in series with the inline separator. Further aspects may also include a surface jet pump upstream of the in-line separator and/or a cyclonic separator downstream of the in-line separator.

An apparatus for separating a fluid mixture includes a uniaxial cyclonic separator () having a separation chamber () for separating the fluid mixture by cyclonic action into a first fluid and a second fluid. An inlet () is located at a first end of the separation chamber () for receiving a fluid mixture, while a first outlet () for the first fluid and a second outlet () for the second fluid are located at a second end of the separation chamber. A gas injection means () is provided for injecting a gas into the fluid mixture to aid separation within the separation chamber (). The gas injection may also be through an annular chamber surrounding the separator chamber (). The gas in this case is introduced through a porous mediumvia a gas supply line

Cyclonic separation system comprising gas injection means and method for separating a fluid mixture

A separation system for separating a fluid mixture includes a uniaxial cyclonic separator () having a first inlet () for receiving a fluid mixture, a separation chamber () for separating the fluid mixture by cyclonic action into a dense first fluid and a less dense second fluid, a first outlet () for the first fluid and a second outlet () for the second fluid. The system further includes a reverse flow cyclonic separator () having a second inlet () for receiving the first fluid from the first outlet (), a separation chamber for separating the first fluid by cyclonic action into a dense third fluid and a less dense fourth fluid, a third outlet () for the third fluid and a fourth outlet () for the fourth fluid. A method for the bulk separation of water from an oil/water mixture is also provided.

A sand separation system includes a first separator () that is constructed and arranged to receive a first mixture of gas, sand and liquid, and separate gas at least partially from the first mixture to leave a second mixture of sand and liquid. A second separator () comprising a uniaxial cyclonic separator is constructed and arranged to receive the second mixture and separate liquid at least partially from the second mixture to leave a third mixture of sand and liquid. A third separator () comprising a gravity separator is constructed and arranged to receive the third mixture and separate liquid at least partially from the third mixture.

A system for pumping multiphase fluids includes a phase separator (), a gas-gas jet pump () and a liquid pump (). The phase separator () receives a LP multiphase fluid and separates a LP gas phase and a LP liquid phase from the LP multiphase fluid. The gas-gas jet pump () receives the LP gas phase from the phase separator () and a HP gas supply from a sustainable gas source, and has an outlet providing outlet gas at a pressure higher than that of the LP gas phase. The liquid pump () receives the LP liquid phase from the phase separator (), and has an outlet providing outlet liquid at a pressure higher than that of the LP liquid phase.
