Packing data

Generalizations are not as easy for structured packings as for random packings. See the following subsection, Comparison to Trays, for study type structured packing data.

Estimation of ligand thickness. The simplest method consists in measuring the thickness s of the ligand layer on space-filling molecular models. When X-ray structures are available, the thickness may be obtained from crystal packing data. However, ligands often have regions of different thicknesses and contain crevasses in which solvent molecules may or may not penetrate.

Compared to experimental data, the above rules of thumb are slightly conservative. Since packing data are usually measured with perfect distribution, a slight conservative bias is necessary to extend... 

Figure 3 Plot of AU and the area ratio R = AVBc/AVBb as a function of the Pt-Pt coordination number N, as obtained from the EXAFS analysis. Also shown is the estimated dispersion, cluster diameter and number of atoms/particle as estimated assuming spherical clusters and FCC packing. Data are shown for the acidic supports (LTL[K/A1=0.63] zeolite and CI-AI2O3, SiOi) and for the basic supports (LTL [K/A1=1.25] zeolite and K-AI2O3, K-Si02).

Kister and Gill (316) modified the Eckert chart curves empirically to fit structured packing data. For structured packings, this modified chart (Fig. 8.19c) was shown (316) to give much better predictions than the Eckert chart. For flow parameters between 0.02 and 0.2 far nonaqueous systems or 0.01 and 1 for air-water, and for packing factors between 6 and 30, Fig. 8.19c was shown (316) to work well for all... 

Values of 0, d, e, and C6, where available, and the range of data used for deriving the correlation, are listed in Table 8.1. For the Sulzer BX packing, data from several systems were used in the correlation deviation, but for corrugated-sheet packings, only air-wator data were used. 

A prerequisite to any interpolation of packing data is thorough familiarity with the factors that affect HETP. These factors are listed in Sec. 9.1.3, and elaborated on in various other sections (which are re-...
