Liquid Load Definitions

Tray liquid load definitions. For tray (as distinct from downcomer) design the liquid load is usually defined as... 

Downcomer liquid load definitions. For downcomer design, the liquid... 

Definitions of tray area, vapor load, and liquid load... 

In concept, this definition describes the flux of liquid across the tray. An alternative definition sometimes used for describing liquid load is the flow parameter, Fw... 

From the definition of the capacity factors and the F factor (see Example 11.1), alternative expressions for the gas and liquid loadings are... 

For definition of the different characteristic resonance frequencies, the locus of impedance Z = R+jX (a) and admittance Y = l/Z = G + jB (h) of a bare quartz crystal are shown in Fig. 12 (for better distinction Rs has been set to 160 12 here, a typical value for single-side liquid load). The definilions are summarized in Table 2 [34]. 

Structured packing is nowadays largely used in industry because of lower pressure drop and higher mass transfer efficiency. There are numerous types. Following Kister (1992), stmctured packing has a definite advantage over modem random packing only at low liquid loads (< 20 gpm/ft2). 

Definition Vertical vane-t separator with inlet baffle for hi liquid loads with liquid removal effldency of 100 percent for particles of 10 microns and larger. See Fig. F-31. 

At total reflux (L/V) = 1) Capps found several points in the FRI data that corresponded with this [241] definition of ultimate capacity, i.e., the liquid and vapor load at which any increase in either liquid or vapor would induce flooding by at least one of the following mechanisms ... 

Equations (3.89) and (3.90) equate the tray active area vapor loading VN to the maximum VM for determining the gas in liquid entrainment flooding of the tray. The early work of Souders and Brown [12], based on a force balance on an average suspended droplet of liquid, led to the definition of a capacity parameter VM- Both VN and Where refer to the active area of the tray. This active area is simply the net tower cross-section internal area less the downcomer areas. The downcomer areas include both the downcomer inlets and outlets.
