Abstract
The present invention concerns a fluid distributor in a multistage column, each plate P of the column being divided into a certain number of panels Pa, and each panel Pa being equipped with a distributor of the invention, said distributor comprising: a) a solid jet breaker located substantially in the axis of the outlet opening of the collecting baffle of the panel Pa; b) an intermediate perforated plate extending laterally beyond the jet breaker, with a degree of opening in the range 10% to 40%; c) a distribution plate extending over the entire panel Pa, and with a degree of opening in the range 5% to 20%.

1-8. (canceled)
A process for simulated moving bed separation comprising:
- providing a device for distributing a fluid to at least one granular bed of a multistage column having a succession of plates, each plate (P) supporting a bed of granular solid and being divided into panels denoted (Pa), said device being applied to each panel (Pa) of a plate (P) equipped with a collecting baffle (5) located immediately upstream of the device, said device comprising the following three elements disposed from top to bottom in the direction of fluid flow:
- a) a solid jet breaker (9) located approximately in the axis of the outlet opening of the collecting baffle of the panel (Pa) and centered on the axis of said collecting baffle;
- b) an intermediate perforated plate (8) extending laterally beyond the jet breaker over a width in the range from the width of said jet breaker to a higher value equal to half the width of the panel plus or minus 5 cm, and with a degree of opening in the range 15% to 30%;
- a distribution plate (7) extending over the entire section of the panel (P), and with a degree of opening in the range 7% to 15% and separating a feed mixture of aromatic compounds containing 7 to 9 carbon atoms.
A process for simulated moving bed separation comprising:
- providing a device comprising:
- A. at least one granular bed of a multistage column having a succession of support plates, each support plate (P) supporting a bed of granular solid and being divided into panels (Pa) with a collecting baffle with an outlet opening, and
- B. a fluid distribution device comprising the following three elements disposed from top to bottom in the direction of fluid flow:
- c) ca solid jet breaker (9) located approximately in the axis of the outlet opening of a collecting baffle of the panel (Pa) and centered on the axis of said collecting baffle;
- d) an intermediate perforated plate (8) extending laterally beyond the jet breaker over a width in the range from the width of said jet breaker to a higher value equal to half the width of the panel plus or minus 5 cm, and extending over less than the entire section of the panel (Pa), and with a degree of opening in the range 15% to 30%;
- e) a distribution plate (7) extending over the entire section of the panel (Pa), and with a degree of opening in the range 7% to 15%, and
- wherein said fluid distribution device is applied to each panel (Pa) of a support plate (P) equipped with the collecting baffle (5) located immediately upstream of the fluid distribution device and separating a feed mixture of aromatic compounds containing 7 to 9 carbon atoms.
