TLDR
In this paper, the experimental data were obtained using forced recirculation of the vapour through the liquid by means of a magnetic pump, and the experimental VLE data were regressed using the Carnahan-Starling-De Santis equation of state, which was chosen for its ability to represent the volumetric properties along bubble and dew point curves.About:
