Measurement and modelling of solid apparition temperature for the CO 2 - H 2 S -CH 4 ternary system

Abstract : In order to develop a new process to eliminate acid gases from natural gas, it is important to consider phase equilibrium properties. New solid-liquid equilibrium data were determined concerning the ternary system CO 2 + H 2 S + CH 4. The experimental technique is based on visual synthetic method. The new experimental data were compared to predictions given by the Predictive Peng-Robinson equation of state (PPR78), PSRK UNIFAC, Peng-Robinson with Huron-Vidal mixing rules and GERG 2008 models coupling with classical approach or Jager and Span for solid phase. The results have shown that the model selected for the fluid phase has more impact that the model considered for the solid phase. New binary interaction parameters of Peng-Robinson equation of state were fitted only on our experimental data and it was found that the obtained values are very different from the value used for Vapor Liquid Equilibrium computation.
