You Are Asked To Evaluate The Possibility Of Using The Distillation Column You Used In The Continuous Distillation Exper 1 (62.99 KiB) Viewed 39 times

You are asked to evaluate the possibility of using the distillation column you used in the continuous distillation experiment to separate water from ethanol. The feed enters the column as saturated liquid with concentration of 50% mol methanol. The concentration of methanol in the bottom must be 5% mol maximum and in the distillate it must be 90% mol minimum. Is the current column is capable of separating this mixture. Determine the minimum reflux ratio. Over all column efficiency. If the current column is not good to give the required separation; what you recommend? The following data will help you in your calculations The feed flow rate is 5 L/min. Reflux ratio is 3 times of the minimum reflux. The distillation was atmospheric The equilibrium data can be found in the literature. In addition to the above make justified assumptions when it is needed. Useful references: W. L. McCabe, J.C.
