Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
ThreePhaseSeparationFunction ⊑ SeparationFunction
Realized in
ThreePhaseSeparationProcess ⊑ SeparationProcess
The identity-giving function is the separation of well fluids into three distinct phases (gas, oil, water). This is a specific subtype of SeparationFunction that distinguishes it from two-phase separators or other separation equipment.
2 Genus DeterminationDeterminação do Gênero
separatorbfo:Object (BFO_0000030)
The parent_candidates show 'FLUID SEPARATOR' from iso15926, but 'separator' is already enriched in our ontology with SeparationFunction and Vessel genus. Three-phase separator is clearly a specialized type of separator, not a general vessel or assembly.
3 Differentia SpecificaDiferença Específica
∃bearerOf.ThreePhaseSeparationFunction

Bears a three-phase separation function that separates fluid streams into gas, oil, and water phases.

The differentia is the specific three-phase separation capability. The genus 'separator' already provides general separation function, so the differentia must specify the three-phase nature which is both necessary (all instances must separate three phases) and sufficient (any separator that separates three phases in this context is a three-phase separator).
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

Three-phase separators require three distinct outlets for the three phases plus the separation chamber where the process occurs. These are universal requirements regardless of specific design variations.

TransformationTransformação
phase separation through gravity and residence time - no chemical change, only physical separation of existing phases
The signature reflects the fundamental three-phase separation process: one multiphase input becomes three single-phase outputs through physical separation.
Disjoint WithDisjunto com
mixer
C4: mixer. Grounded in signature incompatibility: two-phase separators have only two outputs, single-phase vessels have one output, mixers combine phases rather than separate them.
