Abstract
The present invention relates to multi-bed catalytic reactor with a cylindrical shape comprising a distribution device further comprising a feed distributor which is separate from a recycle fluid distributor and thus protects the feed against the higher recycle fluid temperatures.
Claims21
A multi-bed catalytic reactor with a cylindrical shape comprising at least one distribution device, said distribution device comprises at least one recycle fluid inlet and distribution tray adapted to distribute recycle fluid, wherein said distribution device further comprises a separate feed distributor comprising at least one feed inlet and a plurality of feed outlets and adapted to distribute a feed fluid from said at least one feed inlet to said plurality of feed outlets, wherein said feed distributor is separated from fluid connection to said recycle fluid within the distribution device.
A method of distributing a process fluid comprising a gas phase and a liquid phase and possibly a vapor phase, and a feed fluid inside a multi-bed catalytic reactor with a cylindrical shape between an upper catalyst bed and a lower catalyst bed thereof, said method is performed in a distribution device comprising a collection tray comprising at least one recycle fluid inlet;
- a distribution tray adapted to distribute recycle fluid and located below said collection tray;
- a separate feed distributor comprising at least one feed inlet and a plurality of feed outlets, wherein said feed distributor is separated from fluid connection to said recycle fluid within the distribution device, the method comprising the steps of,
- constricting the cross-sectional area of the flow of recycle fluid from the upper catalyst bed to the at least one recycle fluid inlet by means of the collection tray
- flowing the recycle fluid within or partly by-passing the distribution device,
- distributing at least a part of the recycle fluid on to the distribution tray and evenly distributing at least a part of the recycle fluid from the distribution tray over the catalytic bed located below the distribution device,
- providing a feed fluid from a feed inlet to the feed distributor separated from fluid connection to the recycle fluid within the distribution device,
- distributing the feed fluid from the feed inlet to a plurality of feed outlets while keeping the feed fluid separated from fluid connection to the recycle fluid.
