Sieve Tray (KPT TRAY-1)

Sieve Tray (KPT TRAY-1)

Sieve Trays are basically metal plates with holes in them. The fume leaves behind through holes in the plate, the liquid is held on the plate by fume stream. The arrangement, number and size of the holes are the design parameters. Sieve trays have a low maintenance cost and low fouling tendency. They are simple and easy to fabricate, and is relatively inexpensive compared to other mass transfer trays. It is used when turndown is limited to 2:1 and fouling is not a concern.
MOC Stainless steels, 904L, 254SMO, Duplex, SS410S, Titanium, Hastelloy or any metal/composite as indicated by client demand
Key Characteristics Sieve Tray is at minimal expense. Not adaptable for wide scope of turndown proportion. High limit and effectiveness, low pressing factor drop, simplicity of cleaning, and low capital expense.

It is a flat perforated plate with no moving parts & made up of simply metal with holes in them. Vapour passes straight upward through the liquid on the plate. The arrangement, number, and size of the holes are design parameters.

They are simply metal plates with holes in them. Vapour passes straight upward through the liquid on the plate. 

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, the liquid will begin to flow through the perforations rather than into the downcomer. This condition is known as weeping.

They are simple perforated plates with small holes about 5 to 6 mm (0.2 to 0.25 inch) in diameter.
