Scenario

Distillation columns are a canonical P&ID use case because the physical process and the control loops must be legible together. This example shows the main process path and three instrument bubbles without pretending to be a full plant drawing.

Annotation key

equip lines select ISO process equipment symbols.
line ... from ... to ... connects equipment ports and carries line tags.
inst declarations create ISA-5.1 instrument bubbles tied to measured equipment.
