Are there considerations of distribution independent of trays?
Consideration must be given to the correct distribution of vapor and liquid regardless of the type of tray selected. Becker and Bolles have studied the effect of maldistribution on large diameter multipass trays and methods which could be used to offset or prevent maldistribution. One feature of the multichordal or sweptback downcomer which was not stressed is the improved distribution of liquid to the tray below. This reduces the area of stagnant liquid pools, thereby increasing efficiency and flexibility at reduced rates through decreased leakage.
