  • Patent number: 9878298
    Abstract: 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.
