Oil & gas, from the assay to the atmospheric column

The refinery workflows HYSYS was built for — crude characterization, multi-draw fractionation, and hydrocarbon thermo — on a modern browser canvas.

An atmospheric crude column fractionating into ordered side cuts — the same rigorous MESH column solver, on the same canvas you edit in the app.

The same MESH equations, at refinery scale

A multi-draw CDU carves side cuts from the converged tray profile of the proven column solver — not a separate shortcut model bolted on for crude.

Crude distillation (CDU)

Multi-draw atmospheric column — side cuts carved from the converged tray profile.

Live plant integration

Stream tray temperatures and cut yields from your CDU's DCS into this flowsheet's twin comparison — deviations from the converged tray profile are flagged automatically.

Try it yourself

  • ✓Atmospheric / vacuum crude distillation with ordered side-cuts
  • ✓Assay characterization — ASTM D86 / TBP curves → pseudocomponents
  • ✓Peng-Robinson / SRK hydrocarbon thermo + nonlinear pipeline hydraulics
