Vane Type Inlet Devices are (VID) designed in such a way to ensure that the feed is entering the vessel in an ideal manner.That is used to introduce gas/liquid mixtures into a vessel or column. This device is an advanced vane feed inlet device with significantly improved separation efficiency.
The fluids are “sliced” off to either side while flowing through the inlet device. The spacing between the blades typically has been designed using computational fluid dynamics (CFD) to achieve uniform flow.Because the area of the vane inlet is several times larger than the inlet nozzle, the fluid velocities are much smaller, allowing for good gas/liquid separation as well as smooth entry into the vessel.
The purpose of a VID is to decrease the momentum of the feed, perform a first stage separation of solids and liquid from the vapor, and achieve an even vapor distribution across the vessel cross section. This is obtained by splitting the feed mixture into a series of flat jets.
The VID inlet devices achieve a considerable reduction of the vessel height and inlet nozzle sizes compared to conventional inlet devices, and are suitable for installation in horizontal or vertical separators.
We simulated VID to reach a better vane length and number of vane for a specific fluid velocity. Simulation is done within a horizontal three phase separator with inlet piping.
Path lines helped us to see exact path of fluid and distribution pattern within vanes and vessel.
