Method for the simulated moving bed (SMB) separation of a feedstock (F), in which: at least one zone (1, 2, 3, 4) contains fewer than three beds, if the stream (D, E, F, R) delimiting said zone and situated upstream of said zone is injected or withdrawn at the plate Pvia the bypass line L, then the stream delimiting said zone and situated downstream of said zone is injected/withdrawn at the plate Pvia the bypass line L, and if the stream delimiting said zone and situated downstream of said zone is injected or withdrawn at the plate Pvia the bypass line L, then the stream delimiting said zone and situated upstream of said zone is injected/withdrawn at the plate Pvia the bypass line L.

Simulated moving bed separation method and device with reduced number of beds and bypass fluid flow

A radial flow distribution system, a radial flow reactor, and components thereof, including one or more of a scallop, center pipe, and/or outer basket. Each of the scallop, the center pipe, and the outer basket has openings formed therein. wherein the sizes or the shapes of the openings vary along the length or the width of the reactor components such that the openings define a pattern in configured to manipulate and optimize the distribution of flow of feedstock out of the components and through the reactor to maximize the efficiency of the catalyst reaction thereof.

Systems and methods for improving flow in radial flow reactor

The present invention concerns reactors with a radial flow of process stream to be treated comprising improved internals which can be used to minimize the catalytic zones which do not receive any of the process stream which is to be treated. The invention also concerns the use of these radial flow reactors in refining or petrochemical processes.

Fixed bed or moving bed reactors with a radial flow of process stream to be treated, comprising improved internals

Method for the simulated moving bed separation of a feedstock (F), in which when a fluid/effluent (feedstock F, desorbent D, extract E, raffinate R) is injected/withdrawn into/from a chosen plate (P) using an external bypass line (L, L) connected to said chosen plate (P), the flow rate within the said external bypass line (L, L) is controlled in such a way that: a major proportion of the fluid/effluent (F, D, E, R) is injected/withdrawn into/from the chosen plate (P); and a minor proportion of the fluid/effluent (F, D, E, R) is injected/withdrawn into/from the adjacent plate (P, P) connected to the said external bypass line (L, L).

Catalytic reactor () with radial flow of a hydrocarbon feedstock to be treated comprising:

Low-capacity compartmentalized reactor

The present invention describes a type of inclined bed reactor which permits a small quantity of catalyst to be employed. Application of the reactor to a regenerative reforming process.

Inclined bed reactor permitting a small quantity of catalyst to be employed

This invention describes a moving-bed catalyst reactor having radial flow of the feedstock called moving-bed radial reactor, consisting of 3 zones called upper hemispheric body (III), lateral zone (II), and lower hemispheric body (I), the three zones being connected together by means of flanges.

Reduced-capacity moving-bed reactor with radial flow of the feedstock

A scallop, center pipe, and outer basket for use in a radial flow reactor are provided. Each of the scallop, the center pipe, and the outer basket is formed of an elongated conduit having a top end and an opposing bottom end, and a plurality of openings formed in the elongated conduit through a thickness thereof. A diameter of the plurality of openings progressively increases or decreases from the top end to the opposing bottom end of the elongated conduit so as to allow a feedstock to flow radially out through the plurality of openings on the scallop or outer basket, or to allow a feedstock to flow uniformly into the center pipe through the plurality of openings. A system utilizing the center pipe together with either the scallop or the outer basket is also provided.

A device that firstly allows temporary storage of a certain quantity of catalyst and, secondly, allows putting back into circulation of this quantity of catalyst in regenerative reforming installations following an interruption in the circulation of the catalyst.

Device allowing the temporary storage and putting back into circulation of a certain quantity of catalyst in catalytic reforming installations

The present invention describes a catalytic reactor operating as a moving bed to manage interruptions in the circulation of catalyst while at the same time avoiding mechanical damage to the contact means containing the catalyst. The invention also concerns a refining or petrochemicals process using the reactor in accordance with the invention.
