Journal ArticleDOI
Predicting the phase equilibria of CO2+hydrocarbon systems with the PPR78 model (PR EOS and kij calculated through a group contribution method)
TL;DR: In this article, a group contribution method was developed to estimate the temperature dependent binary interaction parameters (kij(T)) for the widely used Peng-Robinson equation of state (EOS), which was called PPR78 (predictive 1978, Peng Robinson EOS).
Journal ArticleDOI
Extension of the PPR78 model (Predictive 1978, Peng-Robinson EOS with temperature dependent kij calculated through a group contribution method) to systems containing naphtenic compounds
TL;DR: Jaubert and Mutelet as mentioned in this paper developed a group contribution method aimed at estimating the temperature dependent binary interaction parameters (kij(T)) for the widely used Peng-Robinson equation of state.
Journal ArticleDOI
Solubility of CO2 in branched alkanes in order to extend the PPR78 model (predictive 1978, Peng–Robinson EOS with temperature-dependent kij calculated through a group contribution method) to such systems
TL;DR: In this article, a high pressure, variable volume visual cell was used to perform static measurements of phase equilibria involving carbon dioxide and four different alkanes: n-heptane, 2,2,4-trimethyl pentane (isooctane), 2,5-dimethyl hexane and 3-methyl pentane.
Journal ArticleDOI
Effect of lifter shape and operating parameters on the flow of materials in a pilot rotary kiln: Part I. Experimental RTD and axial dispersion study
A.S. Bongo Njeng,A.S. Bongo Njeng,Stéphane Vitu,Marc Clausse,Marc Clausse,Jean-Louis Dirion,Marie Debacq +6 more
TL;DR: In this article, the axial dispersion coefficient of the solid particles within a rotary kiln at room temperature and equipped with lifters has been analyzed for the continuous flow of sand and broken rice.
Journal ArticleDOI
Phase equilibria measurements of CO2 + methyl cyclopentane and CO2 + isopropyl cyclohexane binary mixtures at elevated pressures
TL;DR: In this paper, a variable volume high pressure cell, bubble and dew points of the binary systems carbon dioxide + methylcyclopentane and carbon dioxide+ isopropylcyclohexane were measured at temperatures ranging from 292.75 to 373.45 K. The experimental results were correlated with the PPR78 model.
