A sieve tray is a perforated plate tray, with holes punched into the surface area of the deck plate. The holes range from 3/16 to 1 inch. Sieve trays are suitable for applications where turn down ratio is not critical. The vapor passes through the holes and keeps the liquid on the tray deck. These perforated sieve trays are designed to handle high loads and are suitable for all applications where turndown is limited to 2:1 with a medium fouling tendency. With our in-house manufacturing facility and experienced production team, we can assure you that the sieve trays are manufactured to achieve optimum performance.

FAQs
A sieve tray is a type of tray used in distillation columns to facilitate the separation of components in a mixture based on their volatility.
Sieve trays work by allowing vapor to pass through while holding back liquid. They consist of a perforated plate with holes (sieves) through which vapor rises, contacting liquid on the tray. The liquid flows through the perforations, while the vapor continues upward, promoting separation.
Sieve trays are typically made from materials like stainless steel, carbon steel, or other corrosion-resistant alloys. The choice of material depends on factors such as the corrosiveness of the substances being processed and the operating conditions of the distillation column.
Sieve trays offer several advantages, including high efficiency in separating liquid and vapor phases, relatively low pressure drop compared to other tray types, and good resistance to fouling.
Sieve trays are generally simpler in design compared to bubble cap trays. They have higher capacity and efficiency but may be more prone to liquid entrainment. Bubble cap trays, on the other hand, provide better liquid/vapor contact but have higher pressure drops and are more complex to manufacture and maintain.
In distillation, sieve trays play a crucial role in promoting the separation of components with different volatilities. They provide a surface for liquid-vapor contact, allowing the more volatile components to vaporize and rise while the less volatile ones remain in the liquid phase.
