Joule-Thomson coefficients of hydrogen and methane mixtures
Joule-Thomson coefficients for two mixtures of methane and hydrogen gas with hydrogen/methane compositions of 0.127/0.873 mole fraction and 0.5657/0.4343 mole fraction were measured over a pressure range of 135.83-21.39 atm and a temperature range of 294.87-274.38 K. Four experimental isenthalps were generated for each mixture and the data were compared to the predicted values from the original Redlich-Kwong equation of state, with the Soave modification and with the Prausnitz modification, and with the Peng-Robinson equation of state. All the models agree well for the methane-rich mixture, with the Peng-Robinson having the lowest deviation of 3.11%. Agreement for the hydrogen-rich mixture over the entire range was found to be nonsystematic, although the equations showed small deviations for the high-pressure region. The Peng-Robinson equation showed the lowest overall deviation of 3.21%.
