Main benefits of BDH and UFM family
  • 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
Main applications
  • 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 valve

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™ valve

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
UFM tray deck

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.
BDH™ valve
BDH valve

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
