Mesh Pad Mist Eliminator

GTI Solutions mesh pads, G-M™ Wire-Mesh mist eliminators, are knitted mesh pad that are manufactured from woven wires that is crimped and formed into a flat pad and fitted into the tower or separator.  The mist eliminators function primarily on inertia impaction and are efficient in removing droplets, depending upon process conditions and applications.

The selection of mist eliminator is a function of:

 

  • Gas & liquid flow rates and viscosity

  • Expected liquid entrainment

  • Location of mist eliminator to be installed in vessel

  • Allowable pressure drop

  • Level of efficiency to be reached

  • Operating pressure of the application

 

GTI Solutions provides a wide range of mist eliminators, including engineered mist eliminators, to meet every process and application needs.            

 

 

Vane Type Mist Eliminator

G-C Chevron mist eliminators are high capacity separators manufactured from a set of parallel vane plates arranged in a pre-determined geometry as a function of capacity and required performance. 

The geometry of the vanes causes gas to change directions multiple times as it passes through the mist eliminator.  Entrained liquid droplets cannot follow the gas streamlines and impinge upon the walls of the vanes, coalesce to a larger droplet size where they rain down due to gravity and are removed. 

G-C Chevron mist eliminators are preferred over mesh type mist eliminators when there is a concern of fouling, including solid carryover or when the entrained liquid is highly viscous.

Typical applications of G-C-Chevron mist eliminators are:

  • Viscous or sticky liquid that can plug knitted mesh pad mist eliminator

  • Systems prone to fouling or gas stream carrying solid particles along with entrained liquid

  • Application requiring wide operating range or low pressure drops

High capacity G-C Chevron Mist Eliminator uses vanes that are equipped with liquid capture pockets on either side of the wall, which act as drainage channels for the coalesced / capture liquid, shielding it from the vapor flow and thereby avoiding re-entrainment. 

GTI Solutions utilizes latest technology to offer clients the most effective liquid-liquid coalescer that separate a wide range of two immiscible liquids. 

The environmental policies have become increasingly stringent in response to environmental challenges. Policies imposed by governments around the world have implemented regulation that forces the industry to seek assistance of liquid- liquid coalescing technology.

Advantages of Liquid-Liquid Coalescer

  • Reduces cost due to smaller vessel design

  • Capacity increase for existing vessels

  • Higher recovery of valuable products

  • Removal of haziness in the product

  • Technology to remove the most difficult emulsions

  • Reduces waste water production from tankage, separator and desalter

Liquid-Liquid Coalescer

Filter Separator

GTI Solutions' two stage filter separator technology will achieve the smallest possible vessel diameter, thus resulting in the lowest capital investments while removing aerosol liquids and solid particles efficiently.

The first stage contains replaceable coalescing filters mounted on a tube sheet. Here the bulk liquids and solids are removed while coalescing the aerosol liquid droplets into larger ones (greater than 10 microns). 

Some of these coalesced droplets may fall off the filter but the majority is pushed to the second stage due to the high surface velocity. In the second stage, these large droplets are removed by a high capacity and high efficiency Double Pocket Vane, such as G-C-251DP & G-C-351DP.  Filter separators can be designed both vertically and horizontally.

Advantages of Filter Separator

  • Remove aerosol mist to protect downstream equipment from erosion, fouling, pitting corrosion or deactivating of catalyst of molecular sieves

  • Reduces amine or glycol foaming problems by removing solids and free liquid particles from the inlet gas stream

  • Allows low cost vessel designs

  • Debottleneck existing equipment by adding/retrofitting high capacity double pocket vane as a 2nd stage we allow for more capacity without requiring a new separator

  • Protects ultra-low NOx burners from plugging, therefore  preventing furnace heating imbalance

Cyclonic Separator

G-Cyclonic mist eliminator technology provides both mesh pads and vane type mist eliminators work as gravity separators for gas-liquid separation.

When dealing with high pressure (> 1000 psig) application such as separation drum in gas processing or LNG plants, the capacity of these devices is limited due to low liquid to gas density ratios.

Use of G-Cyclonic mist eliminators employs centrifugal force to achieve separation, thereby not limited by gravity separation. The main elements of the axial flow cyclone are a series of cyclone tubes with swirl-body inside the tubes.

 

The gas flows through these tubes and the blades of the swirl-body in the cyclone brings the gas flow into a swirling motion which causes the liquid droplets in the gas stream to migrate to the cyclone tube wall, due to the centrifugal forces generated by this swirling motion.

Benefits of Cyclone Mist Eliminator:

  • High gas handling capacity (vessel gas K value up to < 0.5 m/s)

  • High liquid removal efficiency (> 99% droplets  larger than 10µ)

  • High turndown ratio (factor of 10)

  • Ability to handle slugs

  • Pressure drops varies from 0.3~0.5 PSI (18~34 mbar)

  • Minimize separator size especially the OD

  • Ideal for capacity retrofits in existing separators installed via the manway

  • Removes solids
