Q4 (2 In the process of producing methyl ethyl ketone from butanol, the distillation technique is employed to isolate the desired product from the unreacted butanol. The feed to the column is comprised of a mixture containing 0.90 mol fraction MEK, 0.10 mol fraction 2-butanol, and a negligible amount of trichloroethane. The feed rate and temperature are 20 kmol/h and 35 °C, respectively, while the specifications necessitate a top product of 0.99 mol fraction MEK and a bottom product of 0.99 mol fraction butanol. To effectuate this separation, a column design is required that operates under atmospheric pressure with a reflux ratio of 3. In order to accomplish this, the number of stages needed must first be determined. Additionally, a suitable sieve plate must be designed for conditions below the feed point.
