Engineering Relationships

COALERIS™ addresses fine liquid aerosols and small entrained droplets carried in natural-gas and industrial process-gas streams.
Coalescing media captures fine liquid droplets and promotes their growth into larger droplets that can drain away from the gas stream.
Free liquid, large droplets and slug loading are distinct from fine-aerosol duty and can require upstream bulk separation before a coalescing stage.
Reliable drainage is part of coalescing performance because retained liquid, flooding or re-entrainment can increase carryover and differential pressure.
Gas velocity and turndown influence droplet transport, drainage and re-entrainment risk and therefore belong to application qualification.
Gas composition, pressure, temperature, aerosol loading, liquid properties and upstream solids affect coalescing duty and service behavior.
Element sealing and the intended flow path must be preserved to prevent bypass around the coalescing media.
Downstream protection objectives such as compressors, turbines, fuel-gas equipment and gas-treatment stages can require different validated treatment conditions.
Vessel orientation is an application-equipment decision and does not define the COALERIS™ technology family.
COALERIS™ identifies the filter-element family and does not by itself represent the pressure vessel, separator, drains, level controls, instrumentation or piping as ELIMFILTERS products.
COALERIS™ maps to TC-NG-01 within the COALVEX™ platform.

Fine-aerosol or liquid loading exceeds the validated element duty
Free liquid or slugs reach the coalescing stage without adequate upstream separation
Liquid properties or gas conditions differ from the selection basis
Drain path or liquid-removal capacity is restricted
Gas velocity or turndown behavior promotes re-entrainment
Upstream solid contamination loads or fouls the media
Element sealing or seating allows bypass

Confirm gas composition, pressure, temperature, flow, velocity and turndown.
Determine whether the liquid challenge is fine aerosol, larger droplets, free liquid or a combination.
Characterize aerosol size, liquid loading, liquid properties and upset or slug potential.
Review upstream bulk-separation performance and solid-contamination conditions.
Trend differential pressure against comparable gas flow and process conditions.
Inspect element seating, seals and intended flow path.
Inspect drainage, level-control behavior and evidence of flooding or re-entrainment.
Compare the actual downstream protection requirement with the original selection basis.

Re-evaluate element and media selection when gas or liquid conditions differ from the selection basis.
Correct sealing or seating defects before attributing carryover solely to media performance.
Restore reliable drainage and remove causes of flooding or liquid accumulation.
Add or requalify upstream bulk separation when incoming free liquid, large droplets or slug loading overwhelms the coalescing stage.
Requalify the operating envelope when flow, turndown or liquid loading has materially changed.
Address upstream solids or process contamination that is prematurely loading the coalescing media.

Trend differential pressure together with gas flow and process conditions rather than interpreting one isolated pressure reading.
Inspect drains, liquid-removal paths and level-control behavior for restriction, flooding or accumulation.
At planned element changeout, inspect seating, seals, media condition and evidence of bypass or uneven loading.
Investigate sudden downstream liquid carryover before replacing the element automatically; verify bulk-liquid loading, drainage and process changes first.
Confirm that upstream separation remains adequate when free-liquid or slug conditions change.
