Preconditioning of the Fluid
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.
Coalescence of the Dispersed Phase
Lefilter 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 phase fluid.
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.Lefilter has the expertise and capability to determine
the correct coalescer size and type for your specific process parameters.
Separation of the Dispersed Phase from the Continuous Phase
Once large droplets are formed, they have to be separated. In gas systems, Lefilter 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 medium.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, Lefilter filter 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 filter works with you in all three phase separation steps, the result is greater process efficiency and reduced
operating and maintenance costs.
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 aerosols usually 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.
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,Lefilter coalescers reduce equipment
problems downstream. Fewer and smaller cartridges mean a simpler,more compact system.
