ABSTRACT
In this work, vapor liquid equilibrium data of the carbon monoxide ethylene binary system have been measured at five isotherms ranging from (233.73 to 273.18) K, with pressure ranging from (1.4 to 6.1) MPa. The measurements were performed using a static-analytic apparatus, equipped with two pneumatic rapid on-line sampler injector (ROLSI) capillary samplers, with phase analysis via gas chromatography. The uncertainties in the measurements were within +- 0.02 K, +- 0.6 kPa, and +- 0.003 for temperature, pressure, and mole fractions, respectively. The measured data are correlated using two models, the Peng Robinson equation of state with the generalized a function and the van der Waals mixing rules and the Soave Redlich Kwong equation of state coupled with the Twu et al. a function and mixing rules.
