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.
Two 1000 L tanks connected by 320 m of small plastic pipe. Sweep 0-50 L/min with 5.8 m of usable head.
Atmospheric drainVented tank draining through a valve and five-foot tailpipe. Shows tank head upstream and tailpipe vacuum downstream.
Pressure dropPump 200 gpm of water through 150 ft of 3" pipe with fittings and 30 ft of elevation. Darcy–Weisbach friction + K-factors, end to end.
ChemForge example flowsheets are plain JSON — save any project from the app and the resulting file is shareable. Keep the file handy if you've built one worth bundling; a public contribution channel is planned.
