摘要
Nonideal association in the vapor phase of HF poses a challenge in modeling. In this paper, a hybrid HF equation in the ASPEN Plus process simulation software and an equation of Anderko and co-workers are compared. Lencka and Anderko used a general framework to combine a simple association model with a cubic equation. This formulation helps to represent the phase behaviors of HF and halocarbon mixtures, especially for systems containing two liquid phases.
