Gas-liquid equilibrium rates, Ki = yi/xi

[barbuto]

Hello,

I need tabulated values of Ki = yi/xi for hydrocarbons (unspecified number -- the more I can get, the better) as function of pressure and temperature. There are nomographs like this one in Wikipedia. What I need is a table or set of tables with some (again, the more the better) of those values in numerical format.

Any ideas? Thanks in advance.

tables with Kvalues were common in old days,
my copy of API TDB includes a large collection,
you may find some data on GPSA chapter 25 "Equilibrium Ration (K) data"
Another possibility is to calculate kvalues yourself with a EOS,
details are shown on textbooks as The Properties of Gases adn Liiquids.
On the net you may find Excel pages with the code.

Hello, OldDoc;

Thanks for your reply. I don't think we have neither the API Standard nor the GPSA vade mecum in our local library, but there's a chance that I can find a copy of "The Properties of Gases adn Liquids". I will see. I will also look for Excel spreadsheets that might help me out with that.

Regards,

B.

The GPSA engineering handbook is only $110 (download). Its a lot of "other stuff" but thats just the way it is.
