Dew Points of Quaternary Methane + Carbon Dioxide + Water + Methanol Mixtures. Measurement and Correlation

Experimental measurements of dew points for 14 methane + carbon dioxide + water + methanol mixtures at pressures between 1.0 × 10⁵ and 59.1 × 10⁵ Pa in the temperature range from 241.6 to 288.8 K were made. The experimental results obtained on the quaternary systems were analyzed in terms of a predictive EF−EOS (excess function−equation of state) method, which reproduced experimental dew-point temperature data within an AAD (absolute average deviation) of between 0.0 and 1.9 K.
