Axiomatization Decision Log

Identity-Giving Function
Function class
GasAbsorptionFunction
⊑ DesignedFunction
Realized in
AbsorptionProcess
⊑ MassTransfer
All three sources identify absorption as the identity-giving capability. This distinguishes absorbers from other mass transfer equipment like adsorbers, strippers, or extractors.

Genus Determination
PressureVessel
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.
✓
Expert review — Accepted
"genus: Separator → Vessel → PressureVessel. Separator rejeitado (absorção ≠ separação física). Vessel era interim; refinado para PressureVessel após confirmação de que PressureVessel está enriquecido na ontologia — alinha com heat exchanger na hierarquia."

Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
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⟩
Inputs (I)
FluidMixture
— contains absorbable components
AbsorbentPhase
— selective affinity for target components
Outputs (O)
DepletedFluid
— reduced concentration of absorbed components
RichAbsorbent
— containing absorbed components
Transformation (T)
selective mass transfer of components from fluid mixture to absorbent phase
This signature captures the essential absorption process: selective component transfer between phases while maintaining distinct input/output streams

Axiom Mode Decision

Cross-Standard Observations
ISO 15926 provides the most generic definition while OnePetro focuses on hydrocarbon recovery application. POSC Caesar is minimal. The concept appears consistently as functional across standards despite varying application contexts.
