Sieve trays rely on vapor velocity to exclude liquid from falling through the perforations in the tray floor. If the vapor velocity is much lower than design, liquid will begin to flow through the perforations rather than into the downcomer. This condition is known as weeping. Where weeping is severe, the equilibrium efficiency will be very low.

· Abstract. Approximately half of industrial distillation columns employ trays. Although single-pass and multipass crossflow trays are the most common, there are many other options including dual-flow, baffle, horseshoe, cartridge, and chimney trays. The most prevalent new tray types are augmented crossflow, counterflow, and co-current flow trays.

Why Are My Test Sieve Analysis Results Different?
Here is a list of the six main reasons for not getting repeatable results when conducting a test sieve analysis: 1. The Shape of the Material You Are Sieving. Material with a high aspect ratio, such as rice, or material with a flat, irregular surface, such as cereal, are tough to sieve and obtain repeatable results.
Sieving is a method of using a sieve to distinguish small particles from bigger particles. It is used in flour mills or building sites. Impurities such as husks and stones are extracted from wheat at flour mill. They remove pebbles and stones from sand through sieving.
