The invention relates to a device and method for distributing a liquid and gas in a multiple-bed downflow reactor, such as a hydrocarbon processing reactor, like a hydrocracker. The device comprises respectively the method uses a distributor device comprising a substantially horizontal collecting tray provided with a central gas passage. Gas passing in downward direction through the central gas passage is forced into a swirling motion by a swirler. This swirling motion has a swirl direction around a vertical swirl axis so that the gas leaves the central gas passage as a swirl. At a location above the collecting tray, a quench fluid is ejected into gas in an ejection direction, which is, viewed in a horizontal plane, at least partly opposite to the swirl direction.

Distributor device for a multiple-bed downflow reactor

An apparatus for classifying a mixture of fine and coarse particles in a fluid stream by size or density comprises a housing, a boundary layer momentum transfer device, and an inlet flow control mechanism. The housing comprises an inlet, an interior chamber, and a fine particle outlet. The boundary layer momentum transfer device comprises a plurality of disks stacked in spaced, parallel relation in the interior chamber. The disks are rotatable about a disk axis. The disks have respective central openings cooperatively defining a plenum having a closed axial end and an opposing open axial end. The plenum communicates with spaces defined between each adjacent disk to cooperatively define a fine particle flow path from the interior chamber, through the spaces, through the plenum and the open axial end thereof, and to the fine particle outlet. The inlet flow control mechanism communicates with the interior chamber and provides an adjustable inlet flow path into the interior chamber. The housing can include a cylindrical, conical, and/or scroll-shaped profile.
