Sample Problem No.3
Consider a simple batch still distillation of an ethanol –
water mixture at 101.3 kPa. The initial charge is 100
moles of ethanol at 18% mol and the mixture must be
reduced to a maximum ethanol concentration in the
still of 8% mole. Calculate the amount of distillate and
its composition.
Use the ff. equilibrium data: (Use n = 10)
