An inlet device 10, for use with a fluid separation vessel, comprises: a hollow body 11 provided with a plurality of inlets 12 and a plurality of corresponding outlets 13. Each inlet and its corresponding outlet is connected by a channel (14, Fig 5) through which a single-phase or multi-phase fluid may flow. Each channel has an inlet portion (15, Fig 5) and an outlet portion (16, Fig 5), the inlet portion extending in a first direction through the body and the outlet portion extending in a second direction through the body. The plurality of inlets is configured as a series of concentric apertures 17 centred about an axis which extends in the first direction and subdivided by at least one radial vane 18. The plurality of outlets is configured as a series of adjacent, at least partially annular apertures 19 centred about said axis and subdivided by the said at least one radial vane 18. The outermost inlet apertures 17b lead to the outlet apertures 19a closest to the plurality of inlets (the uppermost outlet apertures), and the innermost inlet apertures 17a lead to the outlet apertures 19b farthest from the plurality of inlets (the lowermost outlet apertures). Advantageously the device may be used with a vapour-liquid separation vessel and provides initial separation and de-foaming of bulk liquids from vapour from a multi-phase input fluid. |
