MIST ELIMINATOR SYSTEM

Why use Mist Eliminators?
Mist  eliminators are simple and effective solution for many seperate problem in the chemical process industry.  We will help you save time, resource, energy and space which results in saving of money.

Save Your Time

  • Mist eliminators separate corrosive products from the gas protecting ducts, pipes and downstream  equipment from corrosion.  Less  corrosion  requires  less  maintenance, inspection and shut down
  • Allows longer  performance cycles before cleaning of mist eliminator is required, reducing downtime

Save Your Resources

  • Mist eliminators save  valuable  products from  exiting  the plant and being lost
  • Protect equipment from corrosive liquid  droplets enhancing the lift of downstream process equipments,  resulting in  less capital costs for new machinery
  • Allows your plant to meet Governement regulated exhaust limits

Save Your Energy

  • Advanced  mist  eliminator  design  which  allows  for  lower pressure droprequirements compared to conventional mist  eliminator, resulting in less energy requirements 

Save Your Space

  • Mist  eliminators  allow  plants  to run at  a higher  flow rate by avoidingproblems of re entrainment, where liquid droplets are picked up by high velocity gas streams. Higher flow rate allow for smaller equipments and duct sizes saving space 
Fiber Bed (Candle) Filters
Fiber bed mist eliminators are shaped in the form of a cylinder with fiber between tow  cages  that  can  be  made  from  many different materials. This type  of mist  eliminator uses  all three separation  mechanisms  namely  i mpaction,  interception and brownian  movement.  We  supply  advanced and conventional    fiber bed mist eliminators suitable for many applications.            Our mist eliminators suitable for  many applications.  Our mist eliminator  maintain  efficiency  requriements  and  minimize  pressure drop.
Mesh (Demister) Pads
Mesh pads are knitted blankets of metal or plastic wire. The primary separation mechanism is interception and imaction.        We manufacture  specialty  mesh pads  using  advanced  technology and metarials such as the  CO-Knit mesh pad ( 99%  efficiency over 2 micron ) and SX mesh pad ( lasts 3-5 times longe r than conventional materials.)
Vane (Chevron) Separators
Vane seperators and lamelia type separations  consisting of specially designed vanes (blades) with a well defined geometry.                            The primary seperation mechanism is interception and impaction. Vanes can be made with a variety  of  materials  ( plastic and metals )    in different  sized  and  configurations.  We  can  manufacture  vance separators in different design to suit customer requirements.
Mist Eleminator Systems – Mesh (demister) Pads
Mesh pads are knitted mesh blankets of metal or plastice wire. They are designed for economical and efficient removal of entrained  loquid droplets from gas streams. We can design and fabricate them in any required size with installation in new or existing process vessels. Mesh pads are normally instralled so that gas flow is upward through the pad. 
How it works
Vapor and  entrained  liquid  droplets pass thtough mesh blankets sandwiched beteween grids.  The vapor moves  freely through the mesh pad but the liquid  droplets due to  their  greater  inertia can  not  make  the  necessary  sharp  angle turns,  and  as  a result are thrown into contact with the wire surfaces. As more droplets enter the pad, they collect  on  the  wire  and  grow  in  size.  Due to their weight the collected droplets will run down the wire to the bottom surface of the mesh separator and fall into the unit. The vapour is now essentially free of entrained liquid.

Typical Applications

Matarial of Construction
Manufacturing mesh pads from a whole range of conventional and specialty materials including :
  • Stainless Steel (316L, 304L, 321, 310 many more)
  • Nickel and Copper
  • Polypropylene and other polyolefins
  • PTFE, FEP, PEA (Teflon)
  • ETFE (Hosteflon/Tefzel)
  • ECTFE (Halar)
  • PVDF
  • Alloy 20 and Alloy 66
  • SX (most preferred material in Sulphuric Acid application
We can also manufacture mesh pads from materials specified by customer for special apllications.
Collection Efficiency and Pressure Drop
Mesh Pads exhibit good collection efficiencies in the range of 2 to 30 microns.
Pressure drop range from 5mm WC to 100mm WC depending on the design of the mesh pad.
Specialty Mesh Pads
  • SX Mesh Pads
SX is metallic alloy with very low corrosion in concentrated Sulphuric Acid giving it a much longer life compared to conventional materials. SX mesh pads do not have the problems of shrinkage and melting associated with PTFE, ETFE and other Fluor Polymers. Many sulphuric Acid plants have upgraded to SX mesh pads. In a recent replacement it was found that the SX mesh pad has performed satisfactorily for fourteen years.
  • Co-Knit Mesh Pads
High Efficiency Co-Knit Mesh Pads
Very high efficiency can be achieved by this design. Long life due to the use of low corrosion material.
Super Structure Co-Knit Mesh Pads
Retains corrosion resistance of Fluor Polymers overcoming shrinkage and support problems.
Metalic Alloy Mesh Pad
Plastic Mesh Pad
