Abstract
An apparatus for use in radial flow reactors is presented. The apparatus includes a first partition and a second partition with support members coupled therebetween. The first partition include a first opening and a second opening to allow the passage of fluid therethrough. A baffle extends into a flow channel formed by adjacent support members to obstruct an upper or lower portion of the first opening to interrupt a portion of the fluid flow therethrough.

A method of making a partition for retaining solid particles in a radial flow reactor, the method comprising
- providing a profile wire screen having a plurality of generally parallel spaced wires supported by a plurality of generally parallel elongate support rods coupled at one edge portion to and extending generally orthogonally across and from the profile wires to define openings;
- forming baffles coupled to and depending from the support rods;
- providing a plate having a plurality of openings;
- arranging the support rods to extend between the profile wires and the plate, with the plate generally parallel to the profile wires so that adjacent support rods define a flow channel in fluid communication with a plate opening and a profile wire screen opening, with an upper support rod defining an upper surface of the flow channel and a lower support rod defining a lower surface of the flow channel;
- and
- positioning at least a portion of a baffle to obstruct an upper portion of the flow channel so that fluid flowing therethrough will be partially obstructed by the baffle portion and attaching opposite edge portions of the support rods to the plate.
A method of making a partition for retaining a solid in a radial flow reactor, the method comprising:
- arranging a plurality of elongate generally L-shaped support rods having a length and two edge portions at opposite end portions of an L-shaped cross section thereof generally parallel to one another and generally defining vertices of an imaginary polygon;
- helically winding a profile wire down the length of the L-shaped support rods with each coil spaced from the adjacent coils, contacting the wire with one of the support rod edge portions, and joining the wire thereto to form a generally cylindrical profile wire defining openings therethrough;
- cutting the profile wire between two of the support rods and opening the cylindrical profile wire screen and flattening the cylindrical profile wire to form a generally flat profile wire screen with the L-shaped support rods extending therefrom with one leg of the L-shaped cross section coupled to the profile wire and extending generally orthogonally therefrom and the other leg of the L-shaped cross section forming a baffle extending generally parallel to the profile wire;
- providing a plate having a plurality of openings therethrough with a plate opening height;
- and
- arranging the profile wire screen and the plate so that the baffles extend vertically downward and cover an upper portion of the plate opening and attaching the L-shaped support rods to the plate.
A method of making a partition for retaining a solid in a radial flow reactor, the method comprising:
- providing a plate having a height, a width, and a thickness;
- forming a first partial opening on one side of the plate through a first portion of the plate thickness having a first upper surface;
- forming a second partial opening on an opposite side of the plate through a second portion of the plate thickness having a second upper surface below the first upper surface so that the first and second openings intersect to form a complete opening through the entire plate thickness so that the portion of the plate above the second upper surface obstructs an upper portion of the first opening.
