Physical-solvent CO2 removal, Rectisol's real solvent
CO2-laden syngas scrubbed by cold methanol — the real Rectisol solvent — then regenerated by a pressure letdown into a flash, no reboiler.
The actual dark-mode canvas: CO2-laden syngas scrubbed by cold methanol in an absorber, then the rich solvent regenerated by a pressure letdown into a flash — the same P&ID symbols you edit in the app.
Physical solvent, not chemical absorption
This is a screening-level Rectisol-style model, honestly scoped: it uses a generic Kremser-shortcut absorber (not the full Rectisol thermodynamics) and reports the regenerated solvent as a product stream rather than closing the recycle loop back onto the absorber feed — real, but not a rigorous Rectisol unit. Compare against the Acid Gas Treating page's mixed-amine process for the chemical-solvent alternative to this physical-solvent route.

A specified equilibrium-stage count absorbing or stripping between two contacted streams.
Isenthalpic Joule-Thomson expansion — the same relation cryogenic JT liquefaction relies on.
Single-stage vapor-liquid equilibrium split at a fixed temperature/pressure.
Stream absorber pressure and treated-gas CO2 slip from your unit's OPC-UA server into this flowsheet's twin comparison — deviations from the solved absorption are flagged automatically.
