Joule-Thompson Coefficient Data for high pressures and temperatures

In summary, the conversation discusses the search for physical data on Joule-Thompson Coefficients in a specific temperature and pressure range, with a request for resources or base papers on the topic. A suggestion is made to consult NIST's REFPROP program for assistance.

Having checked Perry's Handbook and a few other sources, I have yet been able to find physical data for Joule-Thompson Coefficients in temperatures ranging from 200-340 degrees C with pressures around 5000, 10000, and 20000 PSI. Would anyone checking this forum have a resource or base paper to find some information on this topic? Specific gases would include N2, Ar, CO2 which are pretty standard. Any help you could provide would be greatly appreciated.

Check with NIST. They have a program called REFPROP that can do it.

Thank you for bringing this topic to our attention. The Joule-Thompson Coefficient is an important physical property that describes the change in temperature of a gas when it undergoes a pressure drop. It is commonly used in various industrial processes such as refrigeration and natural gas processing.

I understand that you have checked Perry's Handbook and other sources for data on the Joule-Thompson Coefficient at high pressures and temperatures, specifically in the range of 200-340 degrees C and pressures of 5000, 10000, and 20000 PSI. It is possible that the data you are looking for may not be readily available in these sources.

However, there are other resources and research papers that may provide the information you are seeking. I would suggest looking into scientific databases such as Scopus or Google Scholar, which may have more specific and recent studies on the Joule-Thompson Coefficient at high pressures and temperatures. You can also try reaching out to experts in the field or contacting the authors of relevant research papers for further assistance.

In terms of specific gases such as N2, Ar, and CO2, it is important to note that the Joule-Thompson Coefficient can vary for different gases and can also depend on the specific conditions of temperature and pressure. Therefore, it may be useful to broaden your search to include other gases and a wider range of temperatures and pressures.

I hope this helps in your search for data on the Joule-Thompson Coefficient. I commend you for your thoroughness and dedication to finding accurate and reliable information. Good luck in your research.
