Coalescer
ASME U, PP
ISO 9001, 14001

Liquid / COSCO Ind.'s high-efficiency coalescer is recommended for a wide range of gas & liquid filtration
process.
Liquid A coalescer is a technological device performing coalescence. It's primarily used to separate
Coalescer emulsions into their components via various processes, operating in reverse to an emulsifier.
COSCO Ind. can supply Coalescer according to fluid material which needs to be separated.
(CLL Type)
(Liquid-Liquid / Liquid-Gas / Three Phase Separation)

Features
• Reduces cost due to smaller vessel design
• Capacity increase for the existing vessels
• Higher recovery of valuable products
• Removal of haziness in the product
• Reduces blending delays
• Reduces wastewater production from tankage, separator and desalter

Filter Separator
ASME U, PP
ISO 9001, 14001

Liquid-Gas COSCO Ind. two stage filter separator technology allows you to have the smallest possible vessel
diameter, resulting in the lowest cost while removing aerosol liquids and solid particles efficiently.
Separator The first stage contains replaceable coalescing filters mounted on a tube sheet. Here the bulk
(CFS Type) liquids and solids are removed while coalescing the aerosol liquid droplets into large ones. Some
of these coalesced droplets 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
Double Pocket Vane and Mesh Pad.

Features
• ‌Removes aerosol mist to protect downstream equipment from damage, 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, and adding upto 100% more capacity without requiring a new
separator

There are 3 mechanisms that enable droplets to coalesce 

Sizing Considerations
• Inlet nozzle velocity and pressure drop
• Bulk liquid removal / stilling screen
• Velocity through risers
• Liquid loading per element
• Liquid loading per element
• Element spacing / gas velocity
• Vapor disengagement
• Outlet baffle sizing
• Outlet nozzle velocity and pressure drop
