Abstract

A new method based on modifying the McCain method for preparing an EQUATION OF STATE for use in a combinatorial SIMULATION is presented. The method consists of three steps: Breaking down the heavy component and getting agreement with saturation pressure data, grouping, and getting agreement with volumetric data. The heavy component is broken down into 45 single carbon numbers using the gamma function. The critical temperature, the critical pressure and the acentric factor are determined for each single carbon number using the best available correlations. Agreement with the experimental saturation pressure is the obtained by adjusting the molecular weight of the heavy component. The extended composition is the grouped into three multi carbon numbers. The critical properties for the grouped components are the determined in such a way that the original a and b coefficients that were used to get a good fit with the saturation pressure data are maintained. The little deviation caused in calculating the adjusted saturation pressure, as a result of grouping, is corrected by adjusting the critical temperature of the heaviest single carbon number. In the end, volumetric data are fitted using a volume translation parameter as the adjusting parameter. The error obtained in the calculation of the relative volume and the gas phase compressibility factor in the CCE experiments for four samples whose experimental data were ayailable was less than 5%. The errors in obtaining the two phase compressibility factor and the liquid saturation volume in the CVD experiments for the same four samples were under 4% and 15%, respectively. The errors obtained using the original McCain method for the latter two quantities were 8% and 19%, respectively.
