Dry Tray Pressure Drop Of Sieve Trays

摘要

The sieve tray has been in the distillation market place for many decades. This article presents a new correlation for sieve tray pressure drop that incorporates tray thickness, hole diameter and open area, and is compared to data. Dry tray pressure drop is an extremely important hydraulic parameter that aids the tray designer in many different ways. Obviously, it is one of the major contributing parameters in the overall tray pressure drop. But more importantly, its magnitude can tell an experienced designer whether he or she is near flood, is at turndown, has a stable tray or may be approaching spray fluidization. Finally, it can be used to understand the overall behavior and performance of a tray. The Kolodzie and Van Winkle relationship was used as a basis to establish a new correlation. Kolodzie and Van Winkle used a term K to represent the effect of open area, namely hole diameter over hole pitch.
