- Valves oriented parallel to liquid flow direction
- No liquid flow under valves
- Minimized weeping due to lateral vapor release
- Improved turndown ratio compared to round valves
- Improved efficiency/capacity profile compared to conventional round valve trays
- Wide legs and lack of valve rotation reduce damage and wear
- The rectangular shape of the legs prevents spinning and wearing
- Design allows for top side valve replacement
- Available range of valve lifts and weight allow for optimal design
- The unique “umbrella” shape of UFM family offers several key advantages:
- Reduces vertical jetting momentum of vapor, minimizing entrainment and enhancing capacity
- Increases contact area between vapor and liquid on tray deck, improving mass transfer efficiency
- Minimizes pressure drop while maximizing the operating range
Floating valve trays
Sulzer's unique floating valves for higher efficiency and capacity
- Main fractionators of refineries
- Gas concentration columns of refineries
- Light end columns of petrochemical plants
- LNG / NGL fractionation columns
- Absorbers and regenerators of gas sweetening plants
- Biodiesel / Fatty acids
- Olefins / EOEG / BDO / Butylene / Butadiene
- Phenol / Methanol / Solvent Recover
- Sour water stripper
UFM™ Max is a large-size high performance floating valve, it maximizes the hydraulic capacity of a fractionation tray while minimizes the investment.
Key benefits
- Drop-in solution for capacity increase up to 18% in existing column
- Lower CAPEX, reduce column diameter up to 10% lead to saving in material and smaller footprint
- Wide operating range, maintaining good efficiency even at turndown lead to reliable plant performance
- Enhanced separation efficiency, contributing to energy saving and reducing OPEX
- Designed for easy installation and safe inspection access
The unique “umbrella” shape of UFM family offers several key advantages:
- Reduces vertical jetting momentum of vapor, minimizing entrainment and enhancing capacity
- Increases contact area between vapor and liquid on tray deck, improving mass transfer efficiency
- Minimizes pressure drop while maximizing the operating range
Fields of application
UFM Max trays are mainly used in applications requiring both high performances and a wide operating range. It is well-suited for a broad range of applications that typically utilize floating valves, including:
- Fractionation columns in gas processing
- Light ends columns in refinery and petrochemical plants
- Distillation columns operating in varies vapor/liquid loads such as solvent recovery, sour water stripper, fatty acids fractionation, biodiesel and methanol columns
UFM™ is a floating valve which maximizes the hydraulic capacity of a fractionation tray and the operating range.
Functional features
- UFM is a mini-floating type of valve
- UFM provides up to 20% additional capacity compared to conventional sieve and valve trays
- UFM has at least the same operating range as a conventional floating valve
- Minimizes weeping due to lateral vapor release
- UFM valves are oriented parallel to liquid flow direction
- The rectangular shape of the legs prevents spinning and wearing
- UFM is equipped with four dimples to prevent sticking to the tray deck and to enhance fouling resistance
- UFM can be combined with upgraded downcomer technology to achieve maximum tray performance and turndown
Fields of application
UFM trays are mainly used in applications requiring both high performances and a wide operating range, particularly:
- High-pressure columns in gas fields
- Light ends columns in refinery and petrochemical plants.
The unique rectangular-shape sets the BDH™ apart from the conventional valves. The BDH is oriented parallel to the liquid flow direction, providing lateral vapor release and a closed upstream edge to minimize weeping. This contributes to an improved efficiency/capacity profile compared to conventional round valves.
Further advantages of the rectangular valves:
- Improved liquid flow along the flow path on the tray deck
- Wider operating range
- Robust mechanical design due to wide legs
- Anti-rotating which reduces wear and tear
Round valve
We offer round valve trays for replacement or whenever customers request it. There are two types of round valves available: conventional and caged valves.
Available conventional valve types
- RV1 for flat decks
- RV4 for decks equipped with venturi holes for lower pressure drop
Available caged type valves
- RC1 for flat decks
- RC4 for decks equipped with venture holes for lower pressure drop
