| 제목 | Measurement of Vapor-Liquid Equilibria for the Binary Mixture of 1,1,1-trifluoroethane (HFC-143a) + n-butane (R-600) |
| 초록 | Since Kyoto protocol was adopted in 1997, many scientist and engineers have been conducting lots of experiments to replace CFC refrigerant. Although Kyoto protocol contains Kyoto mechanism which can delay the time for developing alternative refrigerants, most countries have to develop alternatives urgently. The restriction will have power on our country from 2013 so the researches have to be accelerated. In view of the situation, mixing HFCs and HCs is a good solution for developing new refrigerants in near future. In this work, VLE data for binary mixture of HFC-143a + n-butane at five 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 and these systems exhibit near azeotropes. |
