Abstract

A particle separating catalytic reactor comprising a kinetic particle separator.

First claim

The invention claimed is:

1. An initial kinetic particle separator for separating particles from an inlet fluid stream of a catalytic reactor comprising a perforated inlet differ having outward perforations, a particle settling chamber, a kinetic particle separator, a collection chamber, and a gas exit channel, the kinetic particle separator comprising an acceleration channel, a flow splitting chamber shaped to subject the inlet fluid stream to multiple changes in direction, and a particle deceleration chamber comprising an angled impingement wall for guiding separated particles from the deceleration chamber to the collection chamber,
wherein the particle settling chamber is located downstream of the perforated inlet diffuser and upstream of the kinetic particle separator, and wherein the particle settling chamber comprises a transfer chimney for transition of the fluid stream from the particle settling chamber to the kinetic particle separator, the transfer chimney arranged in the particle settling chamber and configured to direct the fluid stream from the outward perforations of the perforated inlet diffuser to the acceleration channel of the kinetic particle separator.

2. The initial kinetic particle separator according to claim 1 , wherein the perforated inlet diffuser is in fluid communication with the inlet fluid stream and is in fluid communication with the kinetic particle separator, the kinetic particle separator arranged and configured to change the direction of the fluid stream and separate at least a portion of the particles contained in the fluid stream from the fluid stream at the flow splitting chamber, the kinetic particle separator in fluid communication with the collection chamber via the particle deceleration chamber and in fluid communication with the gas exit channel via the flow splitting chamber, and wherein the particle settling chamber is in fluid communication with the outward perforations of the perforated inlet diffuser and the acceleration channel of the kinetic particle separator.

3. The initial kinetic particle separator according to claim 1 , wherein said transfer chimney is arc shaped.

4. The initial kinetic particle separator according to claim 1 , wherein said kinetic particle separator comprises a plurality of kinetic particle separators arranged in a cluster.

5. The initial kinetic particle separator according to claim 1 , wherein said kinetic particle separator further comprises a screening surface located between the acceleration channel and the particle deceleration chamber, the screening surface comprising supports arranged and configured to allow for passage of particles contained in the fluid stream to the particle deceleration chamber.

6. The initial kinetic particle separator according to claim 1 , wherein said acceleration channel has a variable cross section area.

7. The initial kinetic particle separator according to claim 6 , wherein the variable cross section area is provided by shutting of a part of the cross section by a guide.

8. The initial kinetic particle separator according to claim 1 , further comprising a common serviceable outlet from the collection chamber for removing collected particles.

9. A system comprising a catalytic reactor and the initial kinetic particle separator according to claim 1 , wherein the catalytic reactor comprises a cylindrical body in fluid communication with the gas exit channel of the initial kinetic particle separator.

10. The system of claim 9 , wherein said kinetic particle separator comprises said acceleration channel, flow splitting chamber, particle deceleration chamber, collection chamber and gas exit channel.

11. The system according to claim 10 , wherein said kinetic particle separator comprises a plurality of particle separator units arranged in a cluster.

12. The system according to claim 10 , wherein said acceleration channel has a variable cross section area.

13. The system according to claim 12 , wherein the variable cross section area is provided by shutting of a part of the cross section by a guide.

14. The system according to claim 10 , wherein the kinetic particle separator comprises a common serviceable outlet from the at least one collection chamber for removing collected particles during service.
