A fluid distribution tray that is capable of providing for the distribution of a fluid across a surface area of a bed of contact material contained within a vessel, wherein the fluid distribution tray includes lost area due to a support element upon which the fluid distribution tray is supported within the vessel, wherein the fluid distribution tray includes a plurality of fluid flow means distributed across the fluid distribution tray in a distribution pattern providing for a high density distribution of fluid flow means within a compensation area that is adjacent and near to the lost area and a low density distribution of fluid flow means within the remaining useable area of the fluid distribution tray. Also included is a method providing for a uniform fluid distribution within a vessel.

Fluid distribution tray and method for the distribution of a highly dispersed fluid across a bed of contact material

The invention relates to a distribution device () for distributing liquid over an underlying catalyst bed comprising a horizontal collection tray () provided with at least one gas chimney () for upward or downward passage of gas and with liquid dosing nozzles () for downward passage of liquid, wherein the gas chimney(s) () and liquid doing nozzles () are separate from each other and do not have the same longitudinal axis, and wherein each liquid dosing nozzle () comprises a concentrically arranged liquid passing hole () and splash plate (), wherein the splash plate () is located below the liquid passing hole () and below the collection tray () such that there is a free fall distance for liquid of at least 100 mm between the hole () and the splash plate (). The invention further relates to a reactor for hydroprocessing comprising such distribution device (), the use of such reactor for hydroprocessing and a process for hydrocracking or hydrotreating in such reactor.

Distribution device

The invention relates to a multiple bed downflow reactor comprising vertically spaced apart reaction beds, preferably beds of catalyst particles, and, between adjacent beds, a mixing device for mixing fluids, the mixing device comprising: The invention further relates to the use of such a reactor in hydrocarbon processing.
