11.1 A temperature control system for a distillation column is shown in Fig. E11.1. The temperature T of a tray near the top of the column is controlled by adjusting the reflux flow rate R. Draw a block …

a) A distillation column with a total condenser is separating acetone from ethanol. A distillate concentration of x D = 0.90 mole fraction acetone is desired. Since CMO is valid, L/V = constant. If …

A distillation column, as shown in the figure to the right, is a device used to separate components with different volatilities. In a specific process, a distillation column is used to separate a feed stream …

In an ideal column, the vapor leaving each tray (going up) is in phase The overhead from a distillation column is to have the following composition: A schematic of the top of a distillation column is shown …

A sieve plate distillation column is separating a feed that is 50.0 mol% n-hexane and 50.0 mol% n-heptane. The feed is a saturated liquid. Plate spacing is 24.0 in. Average column pressure is 1.0 atm. …

The overhead product is fed to a second column. The overhead product from the second column contains 94.0% of the B A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and …

D3.* A distillation column separating ethanol from water is shown in the following figure. Pressure is 1.0 kg/cm2. Instead of having a condenser, a stream of pure liquid ethanol is added directly to the …

Question: Study carefully the below given PFD (process flow diagram) of a distillation column. Make a sketch of the plan arrangement for this distillation column with all other equipment.

Question: A distillation column with a partial condenser and a partial reboiler is separating methanol and water. Column pressure is 1.0 atm. We desire 120 kmol/h of a bottoms product that is 0.0001 mole …

A 100 kmol/h stream that is 97 mole% carbon tetrachloride (CCL) and 3% carbon disulfide (CS2) is to be recovered from the bottom of a distillation column. The feed to the column is 16 mole% CS2 and …
