Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
SeparationFunction ⊑ DesignedFunction
Realized in
SeparationProcess ⊑ PlannedProcess
The identity-giving function is the separation of different substances or phases from a mixed stream. This is the core capability that makes a separator distinct from other process equipment like pumps (which move fluids) or heat exchangers (which transfer heat).
2 Genus DeterminationDeterminação do Gênero
Vesselbfo:Object (BFO_0000030)
From the parent candidates, 'vessel' (CFIHOS) is the most specific and ontologically correct genus. Separators are typically cylindrical or spherical vessels (per SLB definition) that contain the separation process. While 'ProcessEquipment' and 'FunctionalObject' are broader categories, and 'Static Equipment' is too general, 'vessel' captures the essential containment structure. Vessel is not yet enriched in our ontology but represents the appropriate level of specificity - more specific than Assembly but more precise than generic ProcessEquipment.
3 Differentia SpecificaDiferença Específica
∃bearerOf.SeparationFunction

A separator is distinguished from other vessels by bearing a SeparationFunction - the designed capability to separate different substances or phases from a mixed fluid stream.

The differentia is solely the SeparationFunction since this is what distinguishes separators from all other vessel types. The genus Vessel already provides the basic containment structure and inlet/outlet capabilities.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These are the minimal parts required for any separation function to occur - an inlet for mixed stream, chamber for separation process, and outlet(s) for separated phases. Specific separation mechanisms (internals, plates, etc.) vary by subtype.
Process Participation SignatureAssinatura de Participação em Processo
InputsEntradas
{'type': 'FluidPortion', 'count': 1, 'constraints': 'mixed multi-phase or multi-component stream'}
OutputsSaídas
{'type': 'FluidPortion', 'count': '≥2', 'constraints': 'separated phases or components with different compositions'}
TransformationTransformação
phase separation or component fractionation without chemical reaction
The fundamental signature is one mixed input stream becoming multiple output streams with different phase or compositional characteristics. This distinguishes separators from mixers (opposite transformation) and reactors (chemical transformation).
Disjoint WithDisjunto com
Mixer HeatExchanger
C4: Mixer, HeatExchanger. Mixers perform the opposite transformation (multiple inputs to one mixed output), reactors perform chemical transformation rather than physical separation, and heat exchangers perform thermal transformation without necessarily separating phases.
