Measurement of Vapor-Liquid Equilibrium for the Binary mixture of Propane (R290) +n-Butane (R600)
CFC alternative refrigerants have been developed for long time. Recently some of them are commercialized and replaced with old ones. Following the tendency of the world, the Korean government recommends installing non-CFCs facilities. Light hydrocarbons can be one of the alternative refrigerants. Although light hydrocarbons are toxic, flammable, and explosive, they are expected alternatives because they are rather cheap, plentiful and environmentally benign chemicals. Also they have low GWP. In this work, isothermal VLE data for binary mixture of propane + n-butane at six equally spaced temperatures between 273.15 and 323.15K were measured by using a circulation-type equilibrium apparatus. The experimental data were correlated with the Peng-Robinson equation of state used the Wong-Sandler mixing rule with combine NRTL excess Gibbs free energy model. Almost all the calculated values with this model give a good agreement with the experimental data. It was pound that this mixture did not show azeotropic behavior over this range of temperature.
