DISTRIBUTOR DEVICE FOR A MULTIPLE-BED DOWNFLOW REACTOR

摘要

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 (20) provided with a central gas passage (30). Gas passing in downward direction through the central gas passage is forced into a swirling motion by a swirler (100). This swirling motion has a swirl direction (107) around a vertical swirl axis (106) so that the gas leaves the central gas passage as a swirl (108). At a location below the collecting tray (20), liquid collected on the collecting tray (20) is injected into the swirl (108) in an injection direction, which is, viewed in a horizontal plane, at least partly opposite to the swirl direction (107).
