Every example below is a real, runnable ChemForge flowsheet. Click a tile to open it in the simulator — components, units, and solver settings are already wired up. Use them to learn the tool, to start your own model, or just to verify a calculation by hand.
Continuous binary distillation with reflux, condenser, and reboiler. A classic teaching flowsheet.
FlashSingle-stage flash drum splitting a multi-component feed into vapor and liquid products.
DistillationPacked distillation column — HETP-based stage equivalence and pressure-drop tracking.
Mass transferGas scrubbing in a packed column. Counter-current liquid contactor with solvent recycle.
VesselsGravity separator vessel with vapor-liquid disengagement sizing.
Hydrogen production via SMR + water-gas shift. Equilibrium reactor with full heat balance.
Heat transferHeat exchanger with hot and cold streams, LMTD calculation, and outlet-temperature solve.
Minimum-boiling azeotrope around 87 mol% IPA. The canonical NRTL teaching example.
VLE diagramMaximum-boiling azeotrope with negative Raoult-law deviation. A great NRTL benchmark.
Specialised thermoHydrogen fluoride flash demonstrating the NRTL liquid model paired with Hayden-O'Connell vapor.
Closed material recycle with Wegstein acceleration. Demonstrates the tear-and-converge solver.
SweepSweep flash temperature and watch product purity move. Demonstrates the Sensitivity Study unit.
BasicsTwo-stream adiabatic mixer. The simplest possible mass + energy balance flowsheet.
BasicsSource → pipe → sink. A sanity check on hydraulics and unit-of-measure conversions.
