Multi-Vane Inlet Devices As member of the family of inlet devices that VME manufactures and provides for its customers, this device introduces the liquids and gases into a pressure vessel in a more gentle manner than the standard splash baffle or vane diffuser style of inlet device. These latter styles can be supplied by VME but are typically part of the vessel fabricator supply.

The process As the fluids (typically a mixture of oil, water and gas) pass through the inlet pipe and nozzle, the flow is split into a number of streams by vanes which are regularly spaced. These then direct the flow of fluids perpendicularly to the inlet flow direction. The fluids velocity is decreased and the bulk of gas and liquids separate. It performs well from low to modest “momentum” values. Flows of high “momentum” values tend to sheer the liquids excessively creating fine droplets.
