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

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 system for the production or handling of heavy oil comprises means () for introducing an immiscible viscosity-reducing fluid into the heavy oil at an upstream end of a flow line () to create a dispersion of oil and viscosity-reducing fluid, and means () for separating the viscosity-reducing fluid at least partially from the oil at a downstream end of the flow line. The separating means comprises a cyclonic fluid conditioning unit () connected receive the dispersion of oil and viscosity-reducing fluid from the downstream end of the flow line (), said cyclonic fluid conditioning unit being constructed and arranged to subject the dispersion to a cyclonic conditioning process; and a gravity separator unit () connected to receive the conditioned dispersion from the cyclonic fluid conditioning unit. The gravity separator unit () is constructed and arranged to allow at least partial separation of the viscosity-reducing fluid from the oil and has a first outlet for the separated viscosity-reducing fluid and a second outlet for the separated oil.

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 cyclonic separator for separating fluids comprises an inlet chamber () having means for inducing fluids flowing through the chamber to swirl around an axis, a cyclonic separation chamber () connected to receive fluids from the inlet chamber, and an outlet chamber () connected to receive fluids from the cyclonic separation chamber. The outlet chamber () has a tangential outlet () for relatively dense fluids and an axial outlet () for less dense fluids. The separation chamber is elongate and has a length L and an inlet diameter D, where L/D is in the range 1 to 10.
