A solvent mixture comprising a solvent and a polar additive and associated methods.

Deposit disintegrator compositions

The present invention relates to a multiple-bed downflow reactor comprising vertically spaced beds of solid contact material and a mixing device positioned in an inter bed space between adjacent beds. The mixing device comprises a loop of first nozzles distributed around a vertical axis and arranged for ejecting a fluid in a first ejection direction into said inter bed space, on the one hand, and a loop of second nozzles distributed around the vertical axis and arranged for ejecting a fluid in a second ejection direction into said inter bed space, on the other hand. The first ejection direction is directed inwardly with respect to the loop of first nozzles. The second ejection direction is directed outwardly with respect to the loop of second nozzles.

Multiple-bed downflow reactor comprising a mixing device, use of said reactor, as well as mixing method

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.
