A distillation column is used to separate an ethanol-water feed into a high purity alcohol and waste water. The feed has a composition of 20 mole % C2H5OH, the distillate contains 85 mole % alcohol and the bottoms have a 3 mole % alcohol concentration. (a) For 2.5 t/h of feed draw a carefully labelled process flow diagram. (b) Calculate the molar flow rates of the distillate and bottom streams. (c) What percentage of the alcohol is recovered in the distillate? (d) Determine the mass fractions of water in each of the input and product streams.

Consider a distillation column that receives a feed of 500 kg/min of a mixture of benzene and cyclohexane that is 55 mole % benzene. We wish to design the column so that the distillate has a composition that is 95 mole % benzene and contains 90 % of the benzene fed to the column. Calculate the distillate and bottoms flow rates (in kg/min) and the composition of the bottoms product in mole %.

Acetaldehyde is synthesized by the catalytic dehydrogenization of ethanol: C2H5OH ? CH3CHO + H2 Fresh feed (pure ethanol) is blended with a recycle stream (95 mole% ethanol and 5% acetaldehyde), and the combined stream is heated and vaporized, entering the reactor at 280?C. Gases leaving the reactor are cooled to -40?C to condense the acetaldehyde and un-reacted ethanol. Off-gas from the condenser is sent to a scrubber, where the uncondensed organic compounds are removed and hydrogen is recovered as a...

A distillation column with a total condenser is separating acetone from ethanol. A distillate concentration of xD = 0.90 mole fraction acetone is desired. Since CMO is valid, L/V = constant. If L/V is equal to 0.8. The distillation column has a partial reboiler that acts as an equilibrium contact. If the bottoms composition is xB = 0.13 mole fraction acetone and the boilup ratio V/B= 1.0, find the vapor composition leaving the second stage above the partial reboiler. a)...

Separation of Acetone and Ethanol A distillation column with a total condenser and partial reboiler is separating acetone and ethanol (equilibrium data is provided in the table below). The feed is 70 mole% acetone, flows at 1000 mol/h, and is a superheated vapor for which one mole of liquid must be vaporized on the feed plate to cool four moles of feed. We desire a bottoms composition of 5 mole% acetone and a distillate composition of 90 mole% acetone. The...

A distillation column should separate benzene and toluene in a 30 t/h feed flow containing 40 % benzene and 60 % toluene. The overhead product should be 97 % benzene and bottom product 98 % toluene. The molar reflux ratio RD = 3.5 and the saturated liquid feed has a boiling point of 95 °C. Calculate flow rates of distillate and bottom product . determine the number of ideal trays needed for the separation . Where is the feed tray...

1.   The liquid product from a flash distillation has a mole fraction of the more volatile component that is lower than the specified liquid purity. Should we decrease, increase, or hold constant the vapor molar flowrate to meet the specified liquid purity? Draw a sketch and explain why? 2.   If the reflux ratio increases, do the molar flowrates for the distillate, bottoms, reflux, and overhead vapor decrease, stay the same, or increase? Support your answer. 3)1000 kmol/h of feed with...

A liquid mixture contains 50 wt% ethanol (E), '10 wt% of a dissolved solute (S) and the balance is water (W). A stream of this mixture F, is fed to a continuous distillation column operating at a steady state. Two streams emerge from the column as the top product, P and the bottom waste Q, respectively. The column design class for the product streams is to have equal mass flow rate, and for the top product stream, P is to...

It is desired to design a distillation column to separate Methanol and Ethanol. One must obtain 100 kmol / hr of distillate with a mol concentration of 0.95 from a liquid stream saturated with 35 mol% of methanol. For this purpose, there will be a Reboiler and a total capacitor that can eliminate 12000 Kcal / h (λ = 40Kcal / Kmol), and allows a return flow of saturated reflux to the tower. If the concentration of bottom product should...
