Formulas and procedures for calculation of detailed tray specifications are presented, for example, by Glitsch Inc. (Bulletin 4900, Ballast Tray Design Manual, Dallas, TX, 1974), and illustrated with a completely solved numerical problem. 

A correlation for valve tray entrainment flooding that has gained respect and popularity throughout the industry is the Glitsch Equation 13 (Glitsch, Inc., Ballast Tray Design Manual, 6th ed., 1993 ...

Manufacturers of valve trays, such as Koch-Glitsch, Inc., of Wichita, Kansas (Ballast trays and Flexitrays), and Sulzer-Chemtech (formerly Nutter Engineering Co.), of Tulsa, Oklahoma (Float Valve Trays), have prepared proprietary design manuals. Hence, only limited discussion will be given here. As for bubble-cap trays, design methods follow those for sieve trays. The vapor capacity chart (Figure 12.29) covers valve trays, as does the alternate method of Kister and Haas. Information on liquid entrainment is proprietary, but measurements have been made by Fractionation Research, Inc. Because of the vapor flow reversal, one would not expect entrainment from valve trays to be greater than that from sieve trays. Liquid capacity considerations follow exactly those for sieve trays. 

To compute the costs of the empty column (or the shell), the diameter of the column is needed. Consider the case where the column is to be operated at 80 percent of vapor flood, and two-pass ballast trays with 24-inch tray spacings are to be used. The column diameter may be estimated by use of the following relationship given by Glitsch.6...
