How do I simulate a distillation?

Open this page and use the live Van der Waals Gas tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a distillation from your own measurements.

where the ideal gas law breaks

Controls

Presets

Attraction a (L²·bar/mol²)

Volume b (L/mol)

Temperature (K)

Real gases deviate from PV = nRT because molecules attract each other (the a term) and occupy volume (the b term). Van der Waals adds both corrections, and below the critical temperature the isotherm even loops — predicting condensation. Educational tool.

▶ Run in Python

Data Inspector

P at V=0.3 L (vdW)86.4 bar

P at V=0.3 L (ideal)88.7 bar

Deviation-3%

Governing equation

(P + \frac{a}{V ^{2}}) (V - b) = R T, a = 1.4, b = 0.039, R T = 26.60

Reading this result: At 320 K the a and b corrections nearly cancel, so the real gas tracks the ideal-gas law to within 3%.

About this simulation

The full Van der Waals Gas tool models a distillation with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
