Acid gas treating, real mixed-amine electrolyte chemistry
Sour gas and lean MDEA/piperazine solvent absorbing both CO2 and H2S in a high-pressure absorber, then stripped in a low-pressure column to regenerate lean solvent.
The actual dark-mode canvas: sour gas contacted with lean MDEA/piperazine solvent in a high-pressure absorber, then the rich amine heated, let down, and stripped to regenerate lean solvent — the same P&ID symbols you edit in the app.
Real electrolyte chemistry, not a generic K-value shortcut
The enrtl-mdea-pz package solves a genuine speciation — MDEA protonation, piperazine carbamate/dicarbamate, and both acid-gas equilibria — with Davies activity, correctly reproducing piperazine's real promotion effect (the blend holds more CO2 at a given partial pressure than MDEA alone), not an assumed selectivity number.

A specified equilibrium-stage count absorbing or stripping between two contacted streams.
Duty- or outlet-condition-specified energy-balance stage.
Isenthalpic Joule-Thomson expansion — the same relation cryogenic JT liquefaction relies on.
Stream absorber/stripper temperatures and treated-gas H2S/CO2 slip from your unit's OPC-UA server into this flowsheet's twin comparison — deviations from the solved loading are flagged automatically.
