Thermodynamic properties of gaseous ethane and ethene+

Abstract

Based on the most probable values and additional recommended values proposed by the High Pressure Data Center of Japan, new equations of state for gaseous ethane and ethene are devised for the range of temperatures 273.15 K to 498.15 K and of pressures up to 30 MPa for ethane and for the range of temperatures 273.15 K to 423.15 K and of pressures up to 80 MPa far ethene. The canonical functions are also derived from the new equations of state, and the thermodynamic property values are calculated by differentiating these functions. The calculated values of compressibility factor, molar volume, molar enthalpy and molar entropy are tabulated in this paper.
