What it does
543 chemicals, A to Z
Chosen for fertilizer, oil and gas and chemical plants, in one alphabetical list for every industry.
Mixtures of up to 12
Presets for natural gas, air, flue gas and synthesis gases, or your own analysis in mole % or mass %.
Full real-gas properties
Z, density, cp and cv with the pressure correction, γ, speed of sound, Joule–Thomson coefficient, viscosity and thermal conductivity.
Heating values
HHV and LHV by mass and by volume, Wobbe index, stoichiometric air and flammability limits.
Hazard data
NFPA 704 ratings, GHS statements, flash point and autoignition temperature.
Every value traceable
Each value shows its source and a data class (A to D), so you know how far to trust it.
Built for engineers
- Open, citable data — reference equations of state, NIST, IUPAC and other published sources; no values copied from handbooks.
- Data class on every chemical — A (reference) to D (indicative), shown next to the result.
- Published methods — Peng–Robinson, Chung, Wilke, Wagner and Le Chatelier, each cited in the Guide tab.
- Built-in checks — warns when the gas would condense, near the critical point and outside each chemical's data range.
For engineering estimates; verify against site data. Code-based methods are aligned with the publicly documented procedure; they are not a licensed reproduction or a certification.
