Extracted text: 2) A distillation column separates 7000 kg/hr of a 60% benzene and 40% toluene mixture. The product D recovered from the condenser at the top contains 94% ethanol and the bottom W contains 96% toluene. A portion of the 4500 kg/hr of vapor stream (V) from the top of the column is returned to the column as reflux (L) and the rest of the distillate (D) is withdrawn for use from the top. 8 Marks] a) Draw the process flow sheet with all the compositions and flows shown correctly (2) b) The flow rates of vapor stream and the bottom discharge stream (3) e) Find the ratio of amount refluxed to the product withdrawn (3)
