Abstract
Apparatus for the treatment of a multiphase fluid, comprises a pretreatment stage (60) upstream of a treatment stage, the pretreatment stage being arranged to cause an incoming flow of multiphase fluid to concentrate fluids of greater and lesser specific gravity into respective flow paths for subsequent treatment in the treatment stage and the pretreatment stage comprising a cyclonic separator device (60) concentrating fluid or fluids of greater specific gravity into an outer annular flow path around an inner flow path for fluid or fluids of lesser specific gravity. The treatment stage comprises a centrifuge having a separator drum (65) rotatable about the axis (66) thereof with an inlet end portion next to the cyclonic separator device (60) comprising concentric inner and outer walls (76, 70) and helical vanes (75) between the walls. The cyclonic separator device (60) comprises radially spaced concentric sleeves with at least one helical fin disposed between the sleeves, the sleeves confining the inner and outer flow paths between them.
