摘要
提出一个简单的相平衡方程描述某些非理想溶液的汽液相平衡关系- 用线性最小二乘法确定方程中的待定系数, 由该方程计算的汽液相平衡组成与实验值较吻合- 将该方程与余国琮和CoullJ方程结合, 可以近似地表示更多的非理想溶液的汽液相平衡关系- 利用该方程导出了计算最少理论板数和最少传质单元数的公式,
A simple phase equilibrium equation for some nonideal solution was presented Undefined coefficients of phase equilibrium equation were solved using the linear least square method The equilibrium composition calculated with this equation was in agreement with experimental data The more vapor-liquid equilibrium relations for nonideal solution were described approximately with this equation, and the equation of Yu Guocong and Coull J The formula for calculation minimum number of theoretical plates and minimum number of mass transfer units was derived by this equation The applications of this equation to distillation were discussed
