the most of pVT softwares are somewhat untrustworthy when it comes to splitting. This can be easily compared by importing the fluid composition and then by choosing splitiing option. As the pseudoization is not computed numericaly, the results should be the same. For example, if you try by splitting and grouping convert composition up to C6+ into a composition up to C7+ in pVTi, mass material balance wont be satisfied. pVTp was checked by Whitsons procedure for Whitson split and it is not the same when calculated manually.
So far, WinProp and above mentioned softwares shown more reliable results, but I havent used Winprop for 7-8 years, pvtx also. PVTsim i.e. CalSep seems to be very good pVT application, but unfortunately, I tried it only for few hours, and we cannot afford it at this moment.
