CC1LG7AH13 Oil and gas filter with fiberglass material for oil and
gas/aviation jet fuel industry
1. Preconditioning of the Fluid
Pall recommends a pre-filter to minimize solids in the coalescer
influent that can plug the coalescer, reducing the overall life and
efficiency. The pre-filter provides peak performance of the
coalescing system and a lower total cost of ownership.
2. Coalescence of the Dispersed Phase
Pall high-efficiency coalescers merge small droplets of liquid into
larger ones as the fluid stream passes through several layers of
filter media, each with progressively larger pores. As droplets
compete for the open pores, they coalesce forming larger droplets.
These larger droplets are easier to separate from the continuous
The coalescer size and type are determined by numerous factors:
physical properties of the fluid, flow rate, process conditions and
chemical compatibility with process fluids and additives.Pall has
the expertise and capability to determine the correct coalescer
size and type for your specific process parameters.
3. Separation of the Dispersed Phase from the Continuous Phase
Once large droplets are formed, they have to be separated. In gas
systems, Pall spaces the cartridges to control the exit velocity of
the gas so that coalesced droplets are not
entrained in this stream.
Filtration: solid particles are removed from the fluid stream by the filter
Coalescence: small droplets are merged into larger ones as they pass through
several layers of filter media in the coalescer.
Separation: gravity takes effect, the large droplets are separated from the
product fluid stream.
In liquid/liquid systems, depending on the liquid to be separated,
Pall will provide a separator cartridge which has “repelling”
properties toward the coalesced liquids. Alternatively, the
assembly can be designed to allow time for the coalesced liquid to
settle.When Pall works with you in all three phase separation
steps, the result is greater process efficiency and reduced
operating and maintenance costs.
Comparison of Liquid/Gas Separation Equipment
The table below compares the various equipment available for
removing aerosols. Only Pall SepraSol coalescers effectively remove
aerosols smaller than one micron.
The Efficient Way to Remove Liquids
Liquid aerosols are formed by three mechanisms: condensation,
atomization, and reentrainment from upstream separation equipment.
Condensation and atomization almost always form very stable, fine
smaller than one micron in diameter.
Such aerosols cannot be removed by “knock-out drums,” mist
eliminators, vane packs, or conventional coalescers. If not
removed, these aerosols can damage downstream equipment.The
solution is Pall’s SepraSol coalescers. They are rated up to 99.99%
removal efficiency for solid particles 0.3 micron and larger,and
reduce liquid content in gas streams down to 0.003 ppm.No other
alternative offers you this level of proven effectiveness.
Higher Liquid Capacity
By handling several times more liquid volume without liquid
reentrainment in effluent gas,Pall coalescers reduce equipment
problems downstream. Fewer and smaller cartridges mean a
simpler,more compact system.
