Refprop 9.0 (Reference Fluid Thermodynamic and Transport Properties) is the gold standard for scientists and engineers needing high-accuracy property data for refrigerants and industrial fluids. While typically installed via a desktop installer, many users require a "portable" version to run the software from a USB drive or across different workstations without administrative privileges.

Here is a comprehensive guide on how to set up, use, and troubleshoot Refprop 9.0 in a portable environment. Understanding Refprop 9.0 Portability

By default, Refprop 9.0 is designed to be installed on a Windows operating system with specific registry keys and file paths. However, the core of the program relies on a collection of DLLs and fluid files (.FLD and .MIX). Because these files are self-contained, you can essentially "portabilize" the software by maintaining the correct folder structure. Why Use a Portable Version?

No Admin Rights: Run the software on restricted office or university computers.

Mobility: Keep your specific fluid mixtures and calculation settings on a thumb drive.

Version Control: Easily switch between 9.0 and newer versions (like 10.0) without installation conflicts. How to Create a Portable Refprop 9.0 Directory

If you already have Refprop 9.0 installed on one machine, follow these steps to make it portable:

Locate the Source: Go to your installation folder (usually C:\Program Files (x86)\REFPROP). Understanding NIST REFPROP 9

Copy Essential Files: Create a new folder on your portable drive named "Refprop_Portable" and copy the following: REFPROP.EXE (The graphical user interface) REFPRP64.DLL and REFPROP.DLL (The calculation engines) The FLUIDS folder (Contains all pure fluid data) The MIXTURES folder (Contains predefined mixture data)

Path Configuration: When you run the .exe from the new location, the software may initially look for fluids in the old C: drive path. Go to Options > Folders within the program to update the search path to your current USB directory. Integration with External Software (Excel & MATLAB)

The primary reason users seek "Refprop 9.0 Portable" is to use it as a backend for other tools. Portable Excel Integration To use Refprop in Excel without a formal installation: Copy REFPROP.XLA (or .XLAM) to your portable folder. Open Excel and go to Developer > Add-Ins. Browse to the portable folder and select the file.

Note: You must ensure the REFPROP.DLL is in the same folder or within the Windows System path for the functions to link correctly. Portable MATLAB Linking

Use the prototypes.m and refpropm.m files. In your MATLAB script, use the addpath command to point to your portable Refprop directory before calling any fluid properties. Key Features of Version 9.0

While Version 10.0 is the most recent, Version 9.0 remains widely used in legacy industrial applications due to its stability. Key features include:

Extensive Database: Support for 121 pure fluids and hundreds of mixtures.

GERG-2008: High-accuracy models for natural gas applications.

Transport Properties: Accurate calculations for viscosity and thermal conductivity, not just pressure-volume-temperature (PVT) data. Troubleshooting Common Portable Issues

⚡ Missing DLL Error: If you get a "DLL not found" error, ensure you have the Microsoft Visual C++ Redistributable installed on the host computer. The portable app cannot bypass the need for these system-level libraries.

⚡ Fluid File Read Error: This usually happens if the folder path is too long (over 256 characters) or contains special characters. Keep your portable folder name simple (e.g., D:\Refprop9).

⚡ Read-Only Issues: If running from a CD or a locked USB, Refprop may crash when trying to save temporary preference files. Ensure the media is writable. Safety and Licensing Note

NIST Refprop is proprietary software. Creating a portable version for your own use is a common workflow, but distributing these files to unlicensed users violates NIST's terms of service. Always ensure your organization holds a valid license for the software before deploying it in a portable format.

If you need to set this up for a specific project, I can help you with the Excel macro setup or provide the MATLAB pathing code. What environment are you planning to use it in?

To create a portable version of REFPROP 9.0 , you can essentially "uncouple" it from the Windows installer by copying its core directory. Since REFPROP is a collection of Fortran-based

calculation engines and data files, it can run from a USB drive or a shared folder without a formal installation on the host machine. Steps to Create a Portable REFPROP Feature Copy the Core Directory : Locate your existing REFPROP installation (typically C:\Program Files (x86)\REFPROP ). Copy the entire folder to your portable device. Verify Vital Subfolders : Ensure the

folders are present. These contain the thermophysical property data required for calculations. Include the Executable : The main file to launch the interface is REFPROP.exe Set Up the Excel Add-in (Optional) : If you want to use REFPROP portably within Excel, copy REFPRP91.XLA

to your drive. When using it on a new computer, you must add its location to Excel's Trusted Locations Key Benefits of a Portable Setup

If you're looking to download or purchase RefProp 9.0 Portable, I recommend visiting the official NIST website or other reputable sources to ensure that you obtain a legitimate and up-to-date version of the software.

You do not need to risk a cracked portable version. Here are legal, low-cost, or free ways to access REFPROP capabilities:

The full REFPROP 9.0 installer is about 180-220 MB. A "portable" version is often compressed to under 50 MB. Why? Because the cracker strips out the high-accuracy fluid files for refrigerants like R-1234yf, R-32, and complex mixtures. You might get pure water and R-134a, but not the specialized fluids needed for modern low-GWP research.

If you are a student, GitHub’s Student Pack gives you free access to many development tools. You can write a simple script using the official ctREFPROP (Community Edition) that calls a legitimate REFPROP installation. Do not download a "portable" GitHub repo containing DLLs—report it instead.

NIST is a US federal agency, but REFPROP is distributed under a paid license via the NIST Standard Reference Data Act. Using a cracked portable version violates:

Corporations caught using unlicensed REFPROP copies face fines of up to $150,000 per copy under the Software & Information Industry Association (SIIA) audits. For a student or freelancer, the risk is lower but real: your university’s IT department actively scans network traffic for known peer-to-peer hashes of illegal software.

For quick, single-point property calculations (density, enthalpy, entropy) for pure fluids, the NIST Chemistry WebBook (webbook.nist.gov) is completely free and requires no download. You cannot plot cycles or do mixtures, but for checking a saturation temperature, it is perfect.

REFPROP 9.0 Portable provides a convenient, high-accuracy toolkit for thermophysical property calculations without full installation overhead. It's suitable for engineering analysis, research, and integration into custom workflows, but be mindful of licensing, dependencies, and potential gaps compared to newer REFPROP releases.
