Selection of a thermodynamic model
This color indicates a link available via Clarkson University (off-campus access)
The weakest link in simulating chemical engineering operations is uncertainty in the physical properties, particularly phase equilibria required for modeling distillation, stripping, absorption and extraction. See, for example, the excellent paper: “Uncovering the realities of simulation,” part 1 Part 2
When possible one should either use experimental data to check the predictions of simulators, or to use these data to fit suitable thermodynamic models.

Henry’s Law states that the solubility of a gas is proportional to its partial pressure, with the constant of proportionality called “Henry’s Law Constant.”
