Distillation Trays

Fenix is able to design and manufacture all types of conventional counterflow trays (with the exception of certain proprietary types) for any column size and from any metallic material that can be worked using punching and bending processes.

Sieve Trays (FXTray-1)

Sieve Tray is type of cross flow tray. Sieve trays are simply metal plates with holes in them.The vapour passes up through perforations in the plate, the liquid is retained on the tray by vapour flow. The arrangement, number and size of the holes are design parameters.

Key Characteristics:

  • Sieve trays are available up to 8.0 m diameter.
  • MOC: Stainless steels, 904L, 254SMO, Duplex, SS410S,
  • Titanium, Hastelloy or any metal/alloy according to customer request
  • Sieve tray is in low cost. Not flexible for wide range of turndown ratio.
  • High capacity and efficiency, low pressure drop, ease of cleaning, and low capital cost


Fixed Valve Tray (FXTray-2)

Valve is the fixed unit punched out of trays at a fixed particular distance. The main advantage of the fixed valve trays is that the high horizontal vapour velocity issuing through the narrow certain area promotes intense radial mixing with the cross flow liquids and deflects entrainment sideways before being swept upward. High vapour velocity eliminates the depositions of solids or fouling. As no moving parts, makes it suitable for corrosive media.

Key Characteristics:

  • Fixed valve trays are available up to 8.0 m diameter.
  • MOC: Stainless steels, 904L, 254SMO, Duplex, SS410S,
  • Titanium, Hastelloy or any metal/alloy according to customer request
  • Fixed valve tray used for wider turndown ratio and better resistance to fouling compared to sieve tray.


Floating Valve Tray (FXTray-3)

Float valves are very efficient to operate at different ‘varying’ flowrates. The legs are provided to maintain the opening of the valve to avoid the weeping and to get the better mass transfer even in lower flow conditions. For some special cases light & heavy valve are also used. Tray open area for floating valve tray automatically changes according to vapour flow rate. Most versatile – can be used for almost all services. Widest turndown ratio. Available in two modules: rotating and non-rotating.

Key Characteristics:

  • Floating Valve trays are available up to 8.0 m diameter.
  • MOC: Stainless steels, 904L, 254SMO, Duplex, SS410S, Titanium, Hastelloy or any metal/alloy according to customer request.


Bubble Cap Tray (FXTray-4)

Bubble cap tray is most oldest & traditional trays. These trays are called as a “liquid sealed” trays, in which the vapour passes up through the short pipes called risers covered by a cap with a serrated edge or slots. At all vapour flowrates a particular liquid level will be maintained on trays. Gives advantage to operate wide range of liquid flow rates.

Key Characteristics:

  • Bubble Caps tray used for 10-100 mm diameter
  • MOC: Stainless steels, 904L, 254SMO, Duplex, SS410S, Titanium, Hastelloy or any metal/alloy according to customer request
  • Bubble cap tray used for low liquid loads. Very wide turndown ratio.


Cartridge Tray (FXTray-5)

Key Characteristics:

  • Normally cartridge tray supplied in small sizes up to 1.0 m diameter.
  • MOC: Stainless steels, 904L, 254SMO, Duplex, SS410S, Titanium, Hastelloy or any metal/alloy according to customer request
  • Cartridge tray is highly suitable for fouling and foaming applications; and for systems which require frequent maintenance or replacement. Wide turndown ratio.


High Capacity Tray (FXTray)

Key Characteristics:

  • MOC: Stainless steels, 904L, 254SMO, Duplex, SS410S, Titanium, Hastelloy or any metal/alloy according to customer request
