STHREEGEE - MESH PAD is wire mesh blanket used to remove process liquid carried over which from's during boiling vacuum evaporations or bubbling Process. THREEGEE MESH PADS consists of multiple layers of knitted and crimped monofilament ( 0.274 mm0) wire mesh fabric. The knitted and crimped mesh increases contact surface and porosity of fabric, prevents blocking and gives constant porosity throughout the metal due to this separation efficiency increases up to 99 % at lower pressure drop & gas velocity.
Increases gas velocity.
► Low-pressure drop► Up to 99% Separation efficiency ►Improves gaseous phase quality ► No loss of liquid phase products ► No limitation in size & shape «Easy to handle & install ► No maintenance or services.
Vacuum Towers, Lube Towers, Distillation Towers, Evaporators, Absorbers, Regenerators, Scrubbers, Strippers, Steam Drums, Moisture Separators, Ventilation Systems, Flame Arresters etc.
Metals i.e. SS 304, 304L, 316, 316L, 321, 430, Nickel, Monel, Inconel, Incolloy, Hastalloy, Alloy 20, Copper and plastics i.e. Polypropylene, Nylon .Teflon (FEP/PTFE)& Hostaflon.
The initial design factor is the velocity of gas through the blanket. If it is too high then separated droplets will re-enter in gas flow by flooding through of mesh blanket and if it is too low then droplet passes through without impingement.
D,= Liquid density-Dg =gas density K = System Constant(o.11) Higher separation efficiency can be obtained by maintaining velocity range up to 30 to 110%by above equation. Pressure drop remains in negligible range of less than 25 mm H2O (WC)
THREEGEE-MESH PADS are manufactured in single piece duly wounded in coiled form for smaller diameter vessels up to 500mm and manufactured in mattresses form in segments for larger diameter vessels above 500mm. The Segments are designed for easy passage through manhole, easy to lift, move and handle, easy to tie by using fixing wire or fasteners
Provided at top & bottom of THREEGEE-MESH PADS has above 90% free area. Grids helps mesh blanket to remain fix on vessel cleat/rings to works suitably against fluctuated operation conditions. Grids are normally made out of 25x3mm thick flats and 6mm0rods in metals and out of 25x5 mm flats in plastics.
Suitable clearance height must be maintained under and above the pads ►For pad diameter below 500mm, clearance should be equal to pad diameter, ► for pad diameter up to 2000mm, it shall be 500mm under and above respectively ► for diameter up to 6000mm it shall be 800mm to 1000mm under and above respectively.
THREEGEE-MESH Pad assembly are passed through vessel manhole or end over and fixed cleats or annular rilng by using fixing wires, Fasteners i.e.' J' Bolts (bottom removal) or Bolts (top removal). If diameter of pad is more than 1500 mm than one or more 'I' beams are provided. Maximum distance of 1 to 1.3 M can be maintained between two beams
