I have a problem finding a steam table for n-pentane

In summary, the conversation involved a person looking for a steam table for n-pentane or pentane, but having difficulty finding one. They were directed to a supplier and also given resources for finding thermodynamic properties of n-pentane, including a T-s diagram and various websites and books. They were also advised to use process simulators for data on C5+ properties.

TL;DR Summary
I was searching long and wide for a steam table for an R601(n-pentane) for the ORC cycle, I need help finding a detailed table.
hey, I was searching for a steam table for a long time but I wasn't lucky, I don't know why an n-pentane, iso-pentane or even pentane table is hard to find , so I am here today asking for a steam table for n-pentane or pentane table, forgive me if I was asking too much, Thank you very much you all.

I found T-s diagrams, phase diagrams, and other properties using search term n-pentane thermodynamic properties. I also searched R601 refrigerant thermodynamic properties, but that did not find much. If you used steam in your search, it probably found information about water because steam generally refers to water in the gaseous state.

Sample T-s diagram from above search:

yeah I don't know why n-pentane (R601) is hard to find, is there a secret they don't want us to know about it's weird, Also thank you very much for your help, I may use this diagram if I didn't find anything new, thank you again

By the way, there is also a figure in Reynolds & Colonna's book Thermodynamics, and some more references to other codes to produce these figures. The book also talks a little about ORCs, it's a very nice engineering book on thermodynamics.

Good Night

Any process simulator will give you the data for C5+ that you need.
Pro II, Hysim, Aspen Suite ect
 

FAQ: I have a problem finding a steam table for n-pentane

Where can I find a reliable steam table for n-pentane?

You can find reliable steam tables for n-pentane in specialized chemical engineering handbooks, academic textbooks, and online databases such as NIST (National Institute of Standards and Technology) Chemistry WebBook or the DIPPR (Design Institute for Physical Properties) database.

Why is it difficult to find a steam table for n-pentane?

Steam tables for n-pentane are less common because n-pentane is not as widely used in industrial applications as other substances like water or ammonia. This makes comprehensive data less readily available in general reference sources.

Can I use general thermodynamic tables for hydrocarbons to get data for n-pentane?

Yes, general thermodynamic tables for hydrocarbons often include data for n-pentane. Resources like the API Technical Data Book and the GPA Midstream Association's Engineering Data Book may provide the necessary thermodynamic properties.

Are there software tools available to generate steam tables for n-pentane?

Yes, there are several software tools available that can generate steam tables for n-pentane. Examples include Aspen Plus, HYSYS, and REFPROP. These tools use extensive databases and equations of state to provide accurate thermodynamic properties.

What specific properties should I look for in a steam table for n-pentane?

In a steam table for n-pentane, you should look for properties such as temperature, pressure, specific volume, enthalpy, entropy, and specific heat capacity. These properties are essential for performing thermodynamic calculations and analyses.
