Semi-formal axiom (Aristotelian)
Axiom type
LLM classification basis: function-based → ≡
The concept is defined purely by its capability of absorption across all sources. Identity is given by the absorption function, regardless of physical implementation (column, vessel, cylinder, etc.).

Axiomatization steps
1
Identity-Giving Function
✓ done
GasAbsorptionFunction → AbsorptionProcess ⊑ MassTransfer
▼
COPI-Core operation
MassTransfer via process parent MassTransfer
LLM rationale:
All three sources identify absorption as the identity-giving capability. This distinguishes absorbers from other mass transfer equipment like adsorbers, strippers, or extractors.

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
Absorbers in oil & gas are vertical, closed pressure-containing vessels operating under process pressure to achieve gas-liquid mass transfer; they satisfy the definition of PressureVessel (pressure boundary, fluid containment under design pressure). PressureVessel (id 60) is the most specific enriched superclass available and is already axiomatized in this ontology. Genus progression: Separator rejected (absorption ≠ physical separation); Vessel accepted as interim genus; refined to PressureVessel after PressureVessel was confirmed as enriched — aligning absorber with heat exchanger in the ontology hierarchy.

Conditions that distinguish
Absorber
from sibling classes under genus
PressureVessel.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
AbsorptionFunction is the minimal differentia that distinguishes absorbers from other separation equipment. It specifies the mass transfer mechanism (absorption into another phase) that defines this equipment type.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
ContactZone é a única parte física universal ao absorber. AbsorbentPhase removido: é fluido de processo, não componente físico do equipamento.

Process Participation Signature ⟨I, O, T⟩
✓ done
FluidMixture + AbsorbentPhase → DepletedFluid + RichAbsorbent
▼
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
This signature captures the essential absorption process: selective component transfer between phases while maintaining distinct input/output streams
