Abstract

A catalytic reactor comprises a particle separator which extracts particles from the fluid flow stream above the reactor internals by means which makes the fluid flow stream perform a radial outwards and upwards S-curve flow path, which enables the particles to be extracted and settle in a collection section with low flow activity and turbulence.

First claim

The invention claimed is:

1. Particle separating catalytic reactor for chemical reactions, comprising a particle separator for separating particles from the inlet fluid stream to the reactor, said particle separator comprises a base plate, at least one inlet channel comprising an inlet channel exit, at least one fluid stream diverter, at least one collection section, at least one transfer chimney comprising a transfer chimney inlet located above the base plate and a transfer chimney outlet located below the base plate, wherein each of the at least one inlet channel exits faces one of the at least one fluid stream diverters and the at least one fluid stream diverters is positioned in a level below the transfer chimney inlet of the at least one transfer chimney, and wherein the at least one fluid stream diverter has a concave shape.

2. Particle separating catalytic reactor according to claim 1 , comprising one inlet channel, one inlet channel exit, one fluid stream diverter and a plurality of transfer chimneys.

3. Particle separating catalytic reactor according to claim 1 , wherein the base plate is adapted to act also as fluid stream diverter.

4. Particle separating catalytic reactor according to claim 1 , wherein the at least one inlet channel has a circular cross section.

5. Particle separating catalytic reactor according to claim 1 , wherein the base plate has a circular shape and the at least one inlet channel exit is located above the centre of the base plate, the at least one fluid stream diverter is located in fixed connection to and in the centre of the on the upper side of the base plate and the at least one transfer chimneys are located in fixed connection to, and in the periphery of the base plate.

6. Particle separating catalytic reactor according to claim 5 , wherein the at least one transfer chimneys are mounted at an inwards angle relative to vertical on the base plate.

7. Particle separating catalytic reactor according to claim 1 , wherein the at least one transfer chimney inlets are facing away from the at least one inlet channel exit and the at least one fluid stream diverter.

8. Particle separating catalytic reactor according to claim 1 , wherein the at least one fluid stream diverter has a circular shape.

9. Particle separating catalytic reactor according to claim 1 , wherein said catalytic reactor is a hydroprocessing reactor.

10. Particle separating catalytic reactor according to claim 1 , wherein the reactor has a dome shaped upper part, the base plate is located beneath or within the lower part of the dome, the particle separator is located within the dome, the at least one inlet channel exit is located near the bottom of the dome relative to the at least one transfer chimney inlet and the at least one transfer chimney inlet is located near the top of the dome relative to the at least one inlet channel exit.

11. Particle separating catalytic reactor according to claim 1 , further comprising a flow conditioner arranged within the inlet channel to ensure plug flow of the inlet fluid stream.

12. Particle separating catalytic reactor according to claim 11 , wherein the flow conditioner is cone shaped and arranged concentric with the inlet channel with the pointed end of the cone upwards, against the inlet fluid stream.

13. Particle separating catalytic reactor according to claim 1 , further comprising at least one inlet channel exit flow divider, dividing the exit flow in a plurality of outlet channels to ensure low flow velocity of the fluid flow exiting the inlet channel.

14. Particle separating catalytic reactor according to claim 13 , wherein the inlet channel exit flow dividers are conical shaped and said plurality of outlet channels have equal inlet areas.
