摘要: In previous work, a generalized quartic equation of state has been developed and extended to polar fluids. There are forty general regressed coefficients used in the four parameters state. Simplification done by setting fifteen those zero obtaining remaining twenty-five from regression on original data base non-polar The results simplification show that can achieve similar accuracy with fewer coefficients. was tested thirty-five binary systems ternary see performance mixtures. mixtures is generally comparable Peng-Robinson
