This method (HEXAMER) was developed by SimSci personnel to predict K-values, enthalpies, entropies, and vapor and liquid densities. It predicts hexamerization of a component in the vapor phase, as well as rigorous two liquid phase behavior. Typically, it is used for HF alkylation processes and for refrigerant synthesis.
A Databank of interaction parameters for typical applications is provided in PRO/II.
See "HEXAMER" under "Equations of State" in Chapter 2, Volume 1, of the PRO/II Reference Manual for more information.
Application Guidelines
HF alkylation columns in which HF is present such as the deisobutanizer, depropanizer and HF stripper.
