Function class
FiltrationFunction ⊑ DesignedFunction
Realized in
FiltrationProcess ⊑ MechanicalSeparation
Reused verbatim from the already-enriched genus 'filter' per the constructive-type rule: a coalescent filter removes contaminants from a fluid stream like any filter, differing only in the mechanism (coalescence of liquid droplets vs. straining of solid particulates).
2 Genus DeterminationDeterminação do Gênero
Filterbfo:Object (BFO_0000030)
Parent candidate GAS FILTER is not itself enriched. Filter (already enriched, genus=Separator, function=FiltrationFunction, exported) is the closest enriched supertype, matching the physical form and general purpose (removing contaminants from a fluid) even though the removed-contaminant phase (liquid droplets, not solid particulates) and mechanism differ.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.CoalescingFilterMedia

Removes liquid particles/droplets from a gas stream specifically, via a layered coalescing media pack that merges small droplets into larger drops for gravity drainage -- as opposed to a generic filter, which strains out solid particulates.

Two independent tertiary patents (triangulated) confirm the layered coalescing media pack as the defining structural element, distinguishing this from both a generic particulate Filter and the vessel-scale Coalescer.

Placeholder empty for Phase 3 -- CoalescingFilterMedia added via the Phase 1b follow-up write once source_definitions_used carries the verbatim tertiary patent quotes.

TransformationTransformação
entrained liquid aerosol droplets coalesced into larger drops within a layered media pack and drained by gravity, separating them from the gas stream
Matches the canonical mechanical_filtration term (size/mechanism-based particle/droplet removal), same category as the genus Filter; two output streams (cleaned gas, drained liquid) reflect the coalescence-specific drainage step.

How much independent secondary research backs this term — not how correct it is. "Full" means a non-primary source was quoted directly and covered several distinct aspects of the concept, not just its function. "Partial" means secondary research happened but covered less. "None" means only the primary definition was used. A "full" term can still contain an error, and a "none" term can still be entirely correct — this tracks whether the research step ran, not the result.Quanto de pesquisa secundária independente sustenta este termo — não o quão correto ele é. "Full" significa que uma fonte não-primária foi citada literalmente e cobriu vários aspectos distintos do conceito, não apenas sua função. "Partial" significa que houve pesquisa secundária, mas com cobertura menor. "None" significa que só a definição primária foi usada. Um termo "full" ainda pode conter um erro, e um termo "none" ainda pode estar totalmente correto — isso rastreia se a etapa de pesquisa ocorreu, não o resultado.

tertiarypatentverbatimUS4759782A[structure, mechanism]
A coalescing filter capable of removing liquid aerosols (such as water and oil) from gaseous streams with high efficiency. Gas coalescers serve to remove aerosol contaminants, both liquid and solid, from gaseous streams.
tertiarypatentverbatimUS7964010B2[structure, mechanism]
Coalescing filters are used to collect liquid that is entrained in a gas stream by causing aerosol droplets of the liquid to coalesce and collect as drops, which can flow as a liquid. They generally comprise several layers of filter media. The droplets can coalesce to form drops, which then collect at the base of the filter element for drainage.
