Sieve Trays

We Attaquant Design and Manufacture Sieve Trays for all types of Distillation Columns. We manufacture in following MOC SS 316L, SS 304, Monel, Inconel, Hastelloy, Titanium, Zirconium etc.
Sieve trays are simple perforated plates with small holes about 5 to 6 mm (0.2 to 0.25 inch) in diameter. Valve trays are similar, except the perforations are covered by small metal disks that restrict the flow through the perforations under certain process conditions.
In sieve trays, vapour flowing up through the tower contacts the liquid by passing through small perforations in the tray floor.
The vapor energy keeps the liquid from flowing down through the holes. The latter moves across the tray and travels to tray below through down-comer. The sieve tray has good capacity and moderate efficiency compared to the valve tray and bubble cap tray, but has limited flexibility in the operating Range.
