[0116] use Figure 3A , 3B and the particle dispersion assembly shown in 3C and the particle flow control assembly shown in Figure 8 to make a figure 2 A similar particle dispersion system is shown. The loading arm system consisted of two inner tubes (similar to inner tube 801 of FIG. 8 ) made of 2.5 inch diameter pipe gauge 10 304 stainless steel 38 inches long from the outer end to the bent end near the axis of the vessel. One inner tube has 9 holes 15 / 32 inches in diameter and the other has 10 holes 15 / 32 inches in diameter, both at the bottom of the arm and along the arm so that the spacing of the holes varies with the distance from the container axis. The radius distance decreases, as shown in Figure 8.
[0117] according to Figure 4 with 5 Template shown, a single deflector was cut from 0.060 inch thick steel plate and bent to form as Figure 3A , 3B , 3C and 7 show the particle dispersion assembly. These assemblies are specifically designed to fit on the distr...

Apparatus for dispersing particles flowing from an orifice comprising a deflecting surface disposed relative to the orifice, wherein the deflecting surface is fixed relative to the orifice, whereby particles flowing from the orifice can impinge upon and can be dispersed by the deflecting surface. The invention also includes an apparatus for loading particles into a vessel comprising particle hopper storage means; at least one rotary loading arm comprising a conduit having a first end and a second end, wherein the first end is in particle flow communication with the particle hopper storage means, and wherein a portion of the conduit has a plurality of orifices disposed between the first and the second end; and a plurality of particle dispersal assemblies, each particle dispersal assembly being disposed adjacent to an orifice, wherein each particle dispersal assembly comprises a deflecting surface which is fixed relative to the orifice such that particles flowing from the orifice can impinge upon and can be dispersed by the deflecting surface. This apparatus includes drive means for rotating the at least one rotary loading arm.
Description
Background technique [0001] Uniform flow of fluid through a packed bed of particulate material is important to the efficient operation of pressure or temperature swing adsorption systems and fixed bed chemical reaction systems. Any significant radial change in fluid axial velocity reduces the effective fluid and solids contact, thereby reducing product purity and recovery in the adsorption system, and reducing overall conversion rates in the chemical reactor. Uniform flow of fluid through a packed bed of particulate material can be achieved by carefully loading the vessel with the particulate material to form a packed uniform bed with continuous and minimal bed pores. [0002] In the art, different types of particle loading methods have been applied to form particle beds of containers. The first and earliest of these methods was the pour charge, in which the granular material was simply poured into a container and leveled by hand. In this method, there is no control over bed...
