Lee-Kesler-Plocker equation of state (Excel version)

Lee-Kesler-Plocker equation of state (Excel version)

Looking for Lee-Kesler-Plocker equation of state software. Lee-Kesler is basic equation of state and LKP is for mixtures calculation. Best option would be program written in Excel.

1. Does someone know for any program?

Aspen is too expensive, Refprop is (as I've heard) not suitable for LKP...

2. I've heard some universities are using those equations for their work or at least use them at teaching. Does someone know any university that do so?

3. Any other options, where can I get it?

RE: Lee-Kesler-Plocker equation of state (Excel version)

there are some books with LKP code, for example Thermophysical Properties of Fluids, Assael, Trusler, Tsolakis,
Plocker has modified rules for Tcm in Lee Kesler to take into account intercations of small molecules with large molecules, otherways code is equivalent to Lee Kesler,
for phase equilibria and other properties in Excel I use Prode Properties, see


which includes LKP model

Try a search of the periodical Chemical Engineering.
