Abstract
Abstract Sievers, U. and Schulz, S., 1980. An equation of state for methane in the form of Bender's equation for temperatures between 91 K and 625 K and pressures up to 500 bar. Fluid Phase Equilibria , 5: 35–54. The coefficients of Bender's equation of state for pure fluid methane are refitted using recent, precise experimental data. This equation of state represents the thermodynamic properties of methane in the fluid region for temperatures between 90.68 K and 625 K, densities up to 28.6 mole dm -3 and pressures up to 500 bar with high accuracy. Only in the critical region is there a slightly lower accuracy. Compared with the results obtained with Bender's original coefficients, improvements are achieved in wide regions, especially for the calculation of vapour-liquid phase equilibria and liquid properties.
