Axiom type
LLM classification basis: function-based → ≡
Scrubber is primarily defined by its function of cleaning/purifying gas streams through liquid washing, not by a specific physical mechanism. Multiple physical implementations exist (static spray, dynamic spray, etc.) that all realize the same gas cleaning function.

SeparationFunction → SeparationProcess ⊑ MechanicalSeparation

COPI-Core operation
MechanicalSeparation via process parent MechanicalSeparation
LLM rationale:
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.

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:
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.

Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The key differentiating feature of scrubbers is their use of liquid washing (water or other liquid) to clean gas. This requires liquid input and a washing process that brings the liquid into intimate contact with the gas stream, distinguishing it from other separation methods.

Necessary Parts

no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
All scrubbers require these basic components to enable gas-liquid contact and separation of clean gas from liquid and contaminants

LLM rationale:
Scrubbers require both gas and liquid inputs, producing cleaned gas and contaminated liquid outputs through liquid washing mass transfer
