Vapor Diffuser (VDS)

Vapor Diffuser

Vapor Diffusers are another type of specialized inlet device for flashing/vapor feeds. Once the feed
enters, a multitude of vanes are used to direct the feed in either a horizontal direction
(as in the left side figure) or in a vertical direction downwards. One advantage of vapor diffuser inlet devices is that the effective blockage of the tower cross-section area is reduced.

Tangential Inlet
Vapor Horn (VDH1)

Vapor Horn

Vapor horns are vapor/flashing feed inlet devices that are commonly specified for the feed
(often two phases) inlets of large-diameter refinery fractionators. The feed enters the column either
via tangential or straight inlet and vanes within the vapor horn housing are used to direct and
distribute the vapor or flashing feed.
