The only available test data [44] indicate that the plain flat plate (26-45% free area) has a decided detrimental effect on the allowable flooding conditions of the tower whereas the wire screen, weir-type, and fused Raschig ring designs have very little effect when using Intalox saddles for packing.

The pilot scale experiments were carried out in a CD column 23 ft (7 m) tall with a total packing height of 16 ft (4.9 m) and a 1 (2.54 cm) nominal I.D. The column is made of 316 SS and consists of 5 sections that are connected by flanges. Two 2 ft (0.6 m) sections located above a 9 ft (2.7 m) stripping section and below a 3 ft (0.9 m) rectification section, were used as the reaction zones, which contained the catalyst. The non-reactive sections were filled with i inch (0.64 cm) Intalox saddles. In the first experiment for which mesityl oxide was synthesized from acetone, the two sections were filled with 130 mL of Amberlyst-15, that had been swelled in 2-propanol for 24 hours, in wire mesh bundles. In the second experiment in which MIBK was synthesized from acetone, the top section and the top half of the bottom section contained 135.0 mL of Amberlyst-15 in wire mesh bundles that had been swelled in acetone for over 24 hours. The bottom half of the bottom section, immediately below the Amberlyst 15, was filled with 50.1 g of a commercial Pd/AlzOs catalyst (Aldrich 20,574-5). The hydrogenation catalyst was reduced ex situ in hydrogen at 350°C for 3 hours and was transferred to the CD column under a nitrogen blanket.

The amount of liquid holdup in the packing is of interest when the liquid is unstable or when a desirable reaction is to be carried out in the vessel. A correlation for Raschig rings, Berl saddles, and intalox saddles is due to Leva (Tower Packings and Packed Tower Design, U.S. Stoneware Co., Akron, OH, (1953) ... 

Intalox saddles and pall rings of 1-1.5-in. size are the most commonly used packings. Smaller sizes tend to be less effective since their voids are of the same order of magnitude as drop...

Table II shows that, as packing size increases, packing capacity rises while packing efficiency decreases. It also shows that both capacity and efficiency are greater for Pall rings and Intalox saddles than for Raschig rings and Berl saddles.

Intalox saddles are available in ceramic only from the Norton Company. Packings that are normally considered equivalent to the Intalox saddles are marketed under the trade names of Flexisaddle by Koch Engineering Company, Inc. and Novalox saddles by Jaeger... 

Figure 7 illustrates in schematic fashion the three column DBBP solvent extraction system. All three columns are made of 304L stainless steel columns and are packed with 1-inch Kynar (Pennwalt Corp.) Intalox saddles. Aqueous and organic phases are mixed by means of air pulses supplied to each column. Important column dimensions are shown in Figure 7. 

Saddle-shaped packings, such as Intalox saddles and Berl saddles, are available in sizes from j to 2 in. These packings are formed from chemical stoneware, plastics, or any other material that can be shaped by punch dies. They form an interlocking structure which gives less side thrust and more active surface area per unit volume than Raschig rings.
