Abstract: Vapor liquid equilibria data were measured for N2-CO2 binary system at 298.43K and for CH4-CO2 system at 298.35K. Ternary vapor liquid equilibria measurements were made for the system N2-CH4-CO2 at 298.3K and 7.25, 7.73 and 8.05 MPa. The data obtained in this work and literature data available on these systems wer ecorrelated by the modified Peng-Robinson equation of state.

摘要： <正>1引言为开发出有经济价值的高纯度CO。气，合适的方法是用吸附分离法脱除CH。和乙、Ce烃，但风难以用吸附法脱去，肉此必须在吸附装置前加一提纯设备以除去比及大部分CH；。考虑能量利用的合理性，希望这一设备能在常温下操作，因而风－CH。－CO。体系在常温下的高压流体相平衡数据就成为提纯装置的设计基础。
