Virial based mixing rules in a modified BWR equation of state

Author

Abstract

"Virial based mixing rules have been developed for a 15 parameter Benedict Webb Rubin (BWR) equation of state. The mixing rules allow for binary, ternary, and higher order interactions; and they allow for partially segregated liquid and vapor phase interaction parameters.

For systems containing hydrogen, methane, ethylene, ethane, propylene and propane, which are of interest to the ethylene petrochemical and gas processing industries, pure component parameters are determined by global regression of vapor pressure, saturated liquid and vapor densities, compressed liquid, superheated vapor and supercritical vapor density. Binary interaction parameters are determined by regression of experimental vapor-liquid equilibrium data as well as mixture density data when available.

With the new mixing rules, the proposed equation reproduces literature vapor-liquid equilibrium data better than commonly used correlations for both narrow and wide boiling point systems. A reduction in the sum of the square error by a factor of 3 is observed when compared to the Lee-Kesler-Plecker equation of state and by a factor of 30 when compared to the Peng-Robinson equation of state"-- Abstract, p. iii
