A plant must distill a mixture containing 70 mol% methanol and 30 mole% water. The overhead product is to contain 99 mol% methanol and the bottom product 1 mol% methanol. The feed is at its bubble point, a total condenser is used with a reflux ratio of 1.8 and with the reflux is at its bubble point. A kettle-type partial reboiler is used; the column is operated at 1 atm.

Use the McCabe-Thiele method to determine the number of trays needed to meet process specifications and the optimal location of the feed tray.

Here I assumed equilibrium line...if you take another equilibrium line then number of stages may vary..I hope you understand well... please ask me if you have any doubts..

Two streams containing a mixture of methanol and water are to be distilled in a distillation column operating at 1 atm. The first stream enters the column closer to the top as a saturated liquid at 73 °C, with a flow rate of 55 kmol/h. The second stream enters the column at the temperature of 90°C closer to the bottom, with a flow rate of 40 kmol/h, at the concentration of 30 mol% methanol. The bottoms stream leaving the reboiler...

1. Obtain the equilibrium mole fractions (liquid and vapor) of a mixture of water, methanol and ethanol at 100 kPa and 70°C. You can assume the mixture is ideal. 2. Create one plot where the equilibrium mole fraction of benzene in the vapor phase is plotted against the equilibrium mole fraction of benzene in the liquid phase for three different pressures (0.2 bar, 0.6 bar and 1 bar). Comment on the effect of pressure on the relative volatility

We are separating a mixture that is 10 mol% methanol, 20 mol% ethanol, 30 mol% n-propanol and 40 mol% n-butanol in a distillation column. The feed is a saturated liquid. We desire to recover 98% of the ethanol in the distillate and 97% of the n-propanol in the bottoms product. The column has a total condenser and a partial reboiler and a feed rate of 100 kmol/hour at 1 atm pressure. The external reflux ratio is 5. In the enriching...

A mixture containing 20 mole % butane, 35 mole % pentane and 45 mole % hexane is to be separated by fractional distillation into a distillate product with a composition 95 mole % butane, 4 mole % pentane and 1 mole % hexane, and a bottoms product. The recovery of butane in the distillate must be 90%. Determine the composition of the bottoms product.

A mixture of fuel containing 0.530 mol CH4/mol, 0.300 mol C3H8/mol, and 0.170 mol C5H12/mol at 59.0°C and 139 kPa (gauge) enters a furnace at a rate of 85.0 L/min where it reacts with 10.0% excess air. Determine the volumetric flow rate of air to the furnace in SCFM (standard cubic feet per minute) by following the steps below. Assume that the gases behave ideally. What is the molar flow rate of fuel entering the furnace? What is the molar...
