Axiomatization Decision Log
1
Identity-Giving Function
Function class
DistillationFunction
⊑ DesignedFunction
Realized in
DistillationProcess
⊑ MassTransfer
The identity-giving function is distillation - the separation of liquid mixtures based on differences in boiling points. This is the same function as any distillation column; the vacuum aspect is a structural/operational characteristic.
2
Genus Determination
DistillationColumn
All three sources explicitly state that a vacuum column IS a distillation column. This is the most specific superclass available. DistillationColumn would itself be an Assembly (complex equipment with multiple integrated components like trays, reboiler, condenser) designed for separation processes.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
Vacuum columns require specialized structural components to handle the external pressure loads and maintain vacuum conditions, beyond what a standard distillation column requires.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
FluidMixture
— multi-component feed suitable for distillation
Outputs (O)
PortionOfLiquid
— overhead product (lighter components)
PortionOfLiquid
— bottom product (heavier components)
Transformation (T)
separation of liquid mixture based on boiling point differences under vacuum conditions
Same separation process signature as any distillation column, but operated under vacuum to enable separation at lower temperatures
5
Axiom Mode Decision
Necessary conditions only
— modelled as a primitive universal
(⊑, SubClassOf). Identity is grounded in designed
function and cannot be reduced to a property checklist.
Constructive type based on structural capability. Under OWA, defining sufficient conditions for vacuum-capable design would be complex and could lead to false positives. The structural differentia (vacuum resistance) requires domain expert validation of what constitutes adequate vacuum design capability.
Cross-Standard Observations
All three sources provide consistent definitions emphasizing the pressure resistance aspect. The definitions are remarkably uniform across ISO 15926, CFIHOS, and POSC Caesar, indicating strong industry consensus on this concept.
