Axiomatization Decision Log
1
Identity-Giving Function
Function class
SeparationFunction
⊑ DesignedFunction
Realized in
SeparationProcess
⊑ MechanicalSeparation
A scrubber's identity is grounded in its function to separate contaminants from gas streams through liquid washing. This is a specialized type of separation function, and 'SeparationFunction' already exists in our ontology for separator equipment. Scrubbers are functionally separators that use liquid washing as their separation mechanism.
2
Genus Determination
Separator
ISO 15926 explicitly states scrubber is a subtype of SEPARATOR, and 'separator' is already enriched in our ontology with SeparationFunction and Vessel genus. This is the most specific appropriate superclass. A scrubber is a specialized separator that uses liquid washing rather than gravity or other separation mechanisms.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
All scrubbers require these basic components to enable gas-liquid contact and separation of clean gas from liquid and contaminants
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfGas
— contains contaminants to be removed
PortionOfLiquid
— washing liquid (typically water)
Outputs (O)
PortionOfGas
— cleaned of specified contaminants
PortionOfLiquid
— contains removed contaminants
Transformation (T)
mass transfer of contaminants from gas phase to liquid phase through washing
Scrubbers require both gas and liquid inputs, producing cleaned gas and contaminated liquid outputs through liquid washing mass transfer
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.
Disjointness Axioms
Compressor
Pump
HeatExchanger
C4: Compressor, Pump, HeatExchanger. Incompatible process signatures - scrubbers perform gas-liquid separation while compressors add energy to gas, pumps add energy to liquid, and heat exchangers transfer thermal energy
Cross-Standard Observations
CFIHOS and POSC Caesar specifically describe scrubber as a 'distillation column' which is more restrictive than other definitions. SLB Glossary is broader, including removal of liquids from gas. OnePetro uses 'reactor' terminology. The liquid washing mechanism is consistent across all sources.
