In Aspen, for pure components, it is necessary to enter the PCSFTM (number of monoparametric segments), PCSFTU (energy parameter), and PCSFTV (segment diameter) values for methane and butane. However, no such data is available online; I seek guidance from experts! ! Leave a message! ! !

I’ve never even heard of it; what do you need these data for?

It seems to be the parameters of the SAFT equation; checking the literature on SAFT should provide these parameter values.
