Predict Distillation Tray Efficiency - AIChE
An empirical technique — the O’Connell correlation — is widely used to estimate the efficiency of cross-flow trays. This article proposes a modification and clarifies the relationship between the empirical and theoretical approaches.
MONTZ-Cross Flow Tray KSG | Montz
The MONTZ-Cross Flow Tray Type KSG is designed as a mass transfer tray with performance characteristics of a valve tray but without moving parts. This design makes is particularly suited for retrofits of existing columns and for multi-purpose distillations.
Consider Moving to Fixed Valves - AIChE
In a conventional cross-flow distillation tray, liquid moves down as vapor moves up. This article discusses moving valves and fixed valves, explains their advantages and disadvantages, and offers guidance on selecting the appropriate valves for distillation trays.

Gas and liquid flow across the tray can either be by cross-flow or counter-flow manner (Figure 7.4). The cross-flow plates are most widely practiced and the three main types of cross flow plates are: bubble cap, valve and sieve trays with downcomer. Figure 7.4. Classification of plate types based on flow mode- side view shown: (a) Cross-flow ...
flow trays are commonly referred to as liquid-liquid cross flow trays. In still other applications, the ascending fluid stream is a gas stream and the descending fluid steam is a liquid stream, in
Types of Trays in Distillation Columns
Dec 21, 2022 · Three types of cross-flow trays are the most commonly used type of vapour and liquid contactors in the distillation columns. In a cross-flow type, the liquid flows across the tray, and the vapours rise up through the plate. The flowing liquid is transferred from the plate to the plate through downcomers.
Cross-flow trays are the most common and least expensive, but parallel-flow trays, if properly designed, can provide an ef-ficiency that is 10% or more higher. Figure 1 depicts a single-pass cross-flow tray. By “pass,” we mean the number of downcomers per tray. As column diameter increases, the ratio. Figure 1. Types of trays.
Cross-flow plates are the most common type of plate contactor used in distillation and absorption columns. In a cross-flow plate the liquid flows across the plate and the vapour up through the plate. A typical layout is shown in Figure. The flowing liquid is transferred from plate to plate through vertical channels called “downcomers”. A pool
