Nist Refprop Program

  1. The following outlines the procedure for using REFPROP within any spreadsheet in Office 2007 or 2010: 1. Open REFPROP.xls and save it as an add-in, REFPROP.xla or REFPROP.xlam, in the main REFPROP folder, C:Program FilesREFPROP. Go to File/Options/Trust Center/Trust Center Settings (button at.
  2. The NIST REFPROP program is designed to provide the most accurate thermophysical properties currently available for pure fluids and their mixtures. The present version is limited to vapor-liquid equilibrium (VLE) only and does not address liquid-liquid equilibrium (LLE), vapor-liquid-liquid equilibrium (VLLE) or other complex forms of phase.

Refprop 10

Refprop

Abstract This is a new release of the NIST Standard Reference Database 23, commonly known as REFPROP. Enhancements have been made to most areas of the NIST REFPROP program, including the graphical interface, the Excel spreadsheet, the FORTRAN files (i.e., core property routines), the sample programs in C, MatLab, VB, etc., and additional fluids. NIST Technical Note 2134. Reference Fluid Thermodynamic and Transport Properties Program – REFPROP, Version 10.0 (Lemmon et al., 2018).

Sources of Property Data for Cryogenic Fluids

NIST has two useful resources that provide thermophysical properties (density, heat capacity, enthalpy, entropy, viscosity, thermal conductivity, etc.) for cryogenic fluids. The first is a free online database known as the NIST Chemistry WebBook. It is for pure fluids only, and fluid properties for selected pure fluids can be accessed here: https://webbook.nist.gov/chemistry/fluid/. At this link you can generate tables or simple plots of properties in a variety of units. A second option is to purchase (at a modest price) the NIST computer program known as REFPROP, which stands for REFerence PROPerties (https://www.nist.gov/srd/refprop). This program provides thermophysical properties for both pure fluids and mixtures, for a wide variety of economically important fluids. It can be run as a stand-alone program with a graphical user interface on Windows machines. Tables as well as a variety of plots can be generated. You can also link to REFPROP via the REFPROP DLL from a variety of 3rd party software programs including Excel, MATLAB, Labview, etc. The source code is also provided (in FORTRAN) and users may write their own calling programs to REFPROP. Additional answers to common questions about REFPROP can be found at REFPROP DOCS.
