Figure 7.10 Some factors affecting sieve tray efficiency. FRI data, total reflux, Dr = 4 ft, S = 24 in, hw = 2 in, dH = 0.5 in. Both parts show a small efficiency rise with pressure. Both parts show little effect of vapor and liquid loads above about 40 percent of flood, (a) Showing efficiency reduction when fractional hole area is increased from 8 to 14 percent of the bubbling area; (b) emphasizing little effect of vapor and liquid loads, and an efficiency increase with pressure. Af = 0.14 (Both parts reprinted with permission from T. Yanagi and M. Sakaia, Ind. Eng. Chem. Proc. Des. Dev. 21, p. 712, copyright 1982, American Chemical Society.}
