Sieve or Perforated Trays
Sieve trays are made from a flat perforated plate which allows the passage of vapor through the liquid. They are the most economical tray option when low turndown is required. They have better anti
fouling characteristics and lower pressure drop than valve or bubble cap trays. Perforations are typically 1/2” diameter, but HUILONG can provide designs with smaller hole size.
Valve Trays
HUILONG valve trays have better turndown and slightly higher efficiency than sieve trays. HUILONG offers different valve selections including fixed valves, floating valves and combination valves. Valve trays cost more than sieve trays, but are more economical than bubble cap trays.
Bubble Cap Trays
Bubble cap trays are best suited for applications with low liquid flows and/or high turndown ratios. In terms of capacity, however, they are slightly lower than valve or sieve trays. They are also the most expensive tray
Dual Flow Trays
Dual flow trays are sieve trays that do not have downcomers. The term dual flow comes from the countercurrent flow of the vapor and liquid through the perforations. Typical perforation sizes range between 1/2” and 1” in diameter. Dual flow trays best suit systems containing a moderate to high solids content or polymerizable compounds. Most often, they are efficient when used in smaller tower diameters.
Baffle Trays
Because of their open design, baffle trays are used in applications requiring high capacity, fouling resistance and low pressure drop. They are well suited for heattransfer applications including heavy oil refining and petrochemical oil refining and petrochemical heat transfer services with high solids or petroleum coke content.
High Strength Trays
For applications with potentially damaging uplift surges, HUILONG can equip trays with special heavy duty features. These include special fasteners, increased tray thickness or additional support beams. Depending upon specific operating criteria, design adjustments can be made to take into account parameters such as corrosion, temperature, vibration and pressure surges. Contact your HUILONG separation specialist for design assistance.
Additional Tray Design Options
For special customer requirements and/or performance, HUILONG Separation Products, Inc. offers numerous tray performance enhancing features. Some of the most common features offered by HUILONG include:
Cartridge Trays Suitable for small diameter body flanges. Can provide up to 5 trays per cartridge. Different sealing options are available.
Anti Jump Downcomer BafflesTo prevent liquids flowing across the tray from jumping over the downcomer onto the opposing flow path. Ant
Jump Downcomer Baffles are standard for multi pass trays with center and off-center downcomers.
Picket Fence WeirsThese are used to decrease the effective weir height. This is for low liquid flows, and using this option will help increase the effective liquid height and prevent blowing.
Splash BafflesFor low liquid rate services, Splash Baffles serve to maximize the liquid retention time on the trays. They can be used in place of, or in conjunction with, picket fence weirs. Splash baffles are located adjacent and parallel to the outlet weir. They clear the tray deck and outlet by 1/2” to 1” forcing the exiting liquid to flow under the baffle before it flows over the top of the outlet weir.
Swept Back WeirsTo reduce the effective liquid height on the tray by lowering the volume of liquid per unit length flowing over the outlet weir. This option should be considered for high liquid flow rates.
Swept Back Weirs are used on side downcomers. They can also be used to balance weir loads between side and off-center downcomers in multi-pass tray designs.
Sloped Downcomers with Recessed Inlet Sumps
Suitable for heavy liquid loads that could otherwise cause downcomer flooding.
