Vapor-liquid equilibrium (PTxy) measurements and modeling for the CO-C 2H4 binary system

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 α function and the van der Waals mixing rules and the Soave-Redlich-Kwong equation of state coupled with the Twu et al. α function and mixing rules.
