A liquid feed at its bubble point is to be distilled in a tray tower to produce the distillate and bottoms as follows: Feed, xAF = 0.047, xBF = 0.072, xCF = 0.881; distillate, xAD = 0.1260, xBD = 0.1913, xCD = 0.6827; bottoms, xBW = 0.001, xCW = 0.999, with a trace amount of component A. Average relative volatilities (α) are αA = 4.19, αB = 1.58 and αC = 1.00. For a feed rate of 100 mol/h, calculate (a) the distillate and bottoms flow rates, and the number of stages at total reflux, (W= 62.7; D= 37.30 kgmol/h) (b) the distribution (trace concentration) of A in the bottoms,

Question

 A liquid feed at its bubble point is to be distilled in a tray tower to produce the distillate and bottoms as follows: Feed, xAF = 0.047, xBF = 0.072, xCF = 0.881; distillate, xAD = 0.1260, xBD = 0.1913, xCD = 0.6827; bottoms, xBW = 0.001, xCW = 0.999, with a trace amount of component A. Average relative volatilities (α) are αA = 4.19, αB = 1.58 and αC = 1.00. For a feed rate of 100 mol/h, calculate
(a) the distillate and bottoms flow rates, and the number of stages at total reflux, (W= 62.7; D= 37.30 kgmol/h)
(b) the distribution (trace concentration) of A in the bottoms,
