Lieberman gives two rules of thumb for troubleshooting fractionators that could also be used as checks on a design. First, the pressure drops across a section of trays must not exceed 22% of the space between the tray decks, to avoid incipient flood. Mathematical , hold [Pg.63]

P = Pressure drop in inches of water SG = Specific gravity of the liquid on the tray at the appropriate temperature T = Number of trays T, = Tray spacing, in. [Pg.63]

For sieve trays, a spray height of 15 inches is obtained when the jetting factor is 6-7. [Pg.63]

U = Hole vapor velocity, ft/sec Pl = Liquid density pv = Vapor density [Pg.63]

For a 15-inch spray height, a tray spacing of at least 21 inches is recommended. [Pg.63]

The development of rehable uv analysis permitted the dependable detection and assay of the provitamins and vitamins. Prior to this, the Lieberman-Bouchard chemical test was used, but the color reaction gave many false positives and was relatively inaccurate. [Pg.132]

Data Acquisition As part or the understanding, the measurements that can be taken must be understood. A useful procedure to prepare for this is to develop a tag sheet for the process (Lieberman, N.P., Troubleshooting Refinery Processes, PennWell Books, Tulsa, 1981, 360 pp). An example of a simplified sheet is given in Fig. 30-5. [Pg.2553]

Packed columns are gaining ground on trayed columns. Lieberman states that based on his design and operating experience, a properly designed packed tower can have 20-40% more capacity than a trayed tower with an equal number of fractionation stages. [Pg.76]

Steam jets require a constant-pressure steam supply for best performance. Pressure below design will usually lower performance and pressure above design usually doesn t increase capacity and can even lower capacity. Lieberman has recommended an intelligent way to handle the problem of variable steam pressure, shown in Figure 1. The steam to the jet is controlled at a pressure... [Pg.197]
