Hello everyone,


As you all know in popular Process simulation software like Hysys, unisim, promax etc  by only providing composition, temperature, pressure one can get a lot of information of a stream like vapor fraction,molar enthalpy,entropy,density,heat capacity,Cp/Cv, Z factor,Watson K, heat of vaporization,kinematic viscosity etc accurately with the help of property package. 



I want to know if there are any practical references,books are available through which we can calculate those property manually( like in excel) accurately? I know there are lot of thermodynamic books are available but they good only for academic. I would like to have practical references from which I can calculate or understand how to calculate above mentioned properties accurately for real life conditions. My area of work are hydrocarbon /petrochemical plants, to some extent air separation plant. 


Presently I am trying to calculate above mentioned properties with Ping Robinson,SRK equation of state for hydrocarbon streams, for my own interest. 


Suggestion for any book, documents or other references(can be premium documents)  would be highly appreciable. Please note that I don't have much access to simulation software, because I am from plant operation side,not from design side.



If the similar question was already asked in the forum and I am repeating the same,then for that I am truly sorry. 



With Regards,


:)  :)  :)

Yes you can check the " Dennis Kirk" webpage, they developed the excel for calculation of Gas Analysis based on GPSA.


I am attaching the file for quick reference.

Get a copy Aspen_HYSYS_Properties_and_Methods_Technical_Reference.


Also, there are excel examples of PR EOS on https://cheguide.com/content.html.

hi bitan.

i started to work in this field before the process simulators, when the computers were very big machines and blocks of punched cards were used for the input.

then i have had the opportunity to work with almost all the process simulators but, in parallel, continued to perform "hand calculations".

based on that, i suggest 4 books:

- gpsa engineering data book

- api data book

- maxwell - data book on hydrocarbons

- reid, sherwood - the properties of gases and liquids

good luck!
