NIST REFPROP 9: The Gold Standard for Thermophysical Property Calculations in Engineering and Science

In the world of chemical engineering, HVAC design, natural gas processing, and academic research, the accuracy of thermodynamic data is not just a convenience—it is a necessity. Errors in fluid properties can lead to catastrophic pipeline failures, inefficient power plants, or pharmaceutical batches that fail quality control. For over three decades, the National Institute of Standards and Technology (NIST) has provided the solution to this challenge. The flagship software, NIST REFPROP 9 (Version 9 of the REFerence fluid PROPerties program), remains one of the most widely cited and trusted tools for calculating the thermophysical properties of pure fluids and mixtures.

When to choose REFPROP 9

  • Choose REFPROP when you require reference-quality, experimentally validated thermophysical properties for fluids and mixtures across wide T–p ranges, especially near-critical and cryogenic conditions, and when the licensing model is acceptable.

NIST REFPROP 9: The Industry Standard for Fluid Properties NIST REFPROP 9.0 (Reference Fluid Thermodynamic and Transport Properties) is a specialized software program developed by the National Institute of Standards and Technology (NIST) to predict the thermophysical properties of industrially important fluids and their mixtures. While newer versions like REFPROP 10.0 have since been released, version 9.0 remains a cornerstone in engineering and research due to its stability, extensive fluid library, and high-accuracy models.
