Souders-Brown correlation

The Souders-Brown correlation considers entrainment as the controlling factor. For high liquid loading situations and final design, complete tray hydraulic calculations are required.

Fair has published a refinement of the Souders-Brown correlation for bubble cap tray capacity, while Glitsch has provided a vapor flooding relationship for valve trays, which also seems to represent bubble cap tray capacity for 3 or 4 in. bubble caps at low pressure.f In the latter, originally developed for valve trays and called equation (13) by Glitsch, the effect of hydraulic liquid head gradient is expressed as an equivalent added vapor load ...

Typically, the separator is a vertical cylindrical vessel equipped with vanes and/or mesh to remove fine droplets of liquid from the gas. Tables for estimating the required diameter of separators for various gas flow rates and conditions are given in several publications, including The API Specification for Glycol Type Gas Dehydration Units (1990) and a paper by Pearce and Si vails (1993). The tables are based on the Souders-Brown correlation, which is quite simple to use directly, i.e..
