For educational use, training, and preliminary feasibility studies only.
Results are based on published thermodynamic correlations (PR EOS, SRK EOS, Peng-Robinson mixing rules, Chapman-Enskog transport)
and must be independently verified by a qualified engineer using licensed process simulation software
(HYSYS, Aspen Plus, REFPROP, VMGSim, or equivalent) before use in any engineering design, procurement,
construction, or safety-critical decision. Accuracy: ±2–5% single-phase EOS; ±5–15% transport properties;
±15–25% near-critical & polar fluids.
DevSan Energy accepts no liability for decisions made on the basis of outputs generated by this tool.
