几点说明 Supplements to Fenske eq.： 3. Another form of Fenske equation
xLD xHB lg x / x HD LB Nm lg L , H
A more convenient form of Fenske equation is obtained by replacing the product of the molar-fraction ratios by the equivalent product of moledistribution ratio in the form of component distillate and bottoms flow rates. 摩尔分率用摩尔数、体积或重量比来代替。
d d lg / b L b H Nm lg L, H
d/b : distribution ratio分配比; d: component flow rate (molar) in distillate; b: component flow rate (molar) in bottoms
