QUESTION 1 [48 MARKS 1. Name two types of distillation columns and list their advantages and disadvantages. (10) 2. Between the two columns, when should each be used? (10) 3. List 8 practical steps adopted in designing a distillation column. (8) 4. Consider the distillation column below and assume a simple binary mixture separation. Perform a material balance in the case where the column has one feed, two products, one reboiler and one condenser. Assume no heat mixing and the component molar latent heats of vaporization to be the same.
