Measurement and modelling of bubble and dew points in the binary systems carbon dioxide plus cyclobutanone and propane plus cyclobutanone

摘要

The fluid phase behaviour for the binary systems carbon dioxide+cyclobutanone and propane+cyclobutanone has been determined experimentally, using Cailletet equipment. For both the systems bubble points have been determined for a number of isopleths covering the whole mole fraction range. Additionally, for the binary system carbon dioxide + cyclobutanone dew points and critical points could be observed for a number of overall-compositions rich in carbon dioxide. The temperature and pressure range were, respectively, from 278 to 369 K and from 0.1 to 14.0 MPa. Correlation of the experimental data of both systems has been performed using the Soave-Redlich-Kwong (SRK) equation of state. Satisfactory results have been achieved using only one binary interaction parameter. (C) 2003 Elsevier B.V. All rights reserved. [References: 14]
