Glycol dehydration, a real two-stage regeneration
Wet natural gas contacted with lean TEG in an absorber, then rich glycol regenerated across two flashes to meet pipeline water spec.
The actual dark-mode canvas: wet gas contacted with lean TEG, then rich glycol let down and regenerated across two flashes to strip dissolved methane and boil off absorbed water — the same P&ID symbols you edit in the app.
Why two regeneration stages, not one
The first flash strips the bulk of the methane the rich glycol co-absorbed at high pressure; the second, hotter flash then boils the water off the now nearly gas-free glycol — the same degassing pattern this codebase's physical-solvent CO2 example uses, because skipping the first stage would carry methane straight into the water-boiling step.
