✦ Synopsis

The constants of the Bender equation of state were determined for ethane and propane. For these two substances and for methane, ethylene and propylene pressure~nthalpy diagrams and tables of saturation properties were calculated. Pressure-enthalpy diagrams for methane, ethane, propane, ethylene and propylene K. Buhner, G. Maurer and E. Bender Nomenclature ai coefficients of the equation of state b i coefficients of the equation for ideal gas state heat capacity cg ideal gas state heater capacity fm mean percentage deviation p pressure R universal gas constant T, t temperature h specific enthalpy s specific entropy p density Riedel-parameter Indices L saturated liquid V saturated vapour c at the critical point calc calculated exp experimental Pressure-enthalpy diagrams as well as tables of saturation properties are frequently needed in cryogenic engineering. This paper presents this information for five low boiling hydrocarbons, namely methane, ethane, propane, ethylene and propylene. The diagrams and tables were generated from the Bender equation of state together with literature data on the ideal gas state heat capacity. The tables of saturation properties cover the region between about 104 Nm -2 (0.1 bar) and the critical pressure. The pressure-enthalpy diagrams cover the liquid and vapour region at pressures between 104 and 10SNm -2 (0.1 and 1000 bar) and temperatures from the boiling point at 104Nm -2 (0.1 bar) up to 300°C.
