Keywords: heavy paraffinic mixtures, thermodynamic model, phase behaviour
In order to set-up a reactor model, the thermodynamic behaviour is the first basic requirement. For this reason, while building a complete model of a reactor, some thermodynamic data were measured in order to check the reliability of the thermodynamic part of the model. In particular, phase behaviour and phase density measurements were performed on mixtures of a heavy paraffinic stream + hydrogen.
Two samples were considered. The first one comprising only linear paraffins and the second one including isomers. The following conditions ranges were explored: H2/sample ratio from 0.06 to 0.10 wt/wt, temperature from 200 to 300 °C and pressure from 25 to 70 bar.
These data were employed to assess the performances of a previously proposed thermodynamic model (S. Correra, D. Molinari, L. Pellegrini, V. Calemma, “Thermodynamic Characterization of Heavy Paraffin Mixtures to Employ the Soave-Readlich-Kwong Equation of State”, AIChE 2006 Spring National Meeting, April 23 – 27, 2006, Orlando, FL).
In this paper, results of this assessment are described.
