Problem 4.40 Sequential Distillation A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation column. The bottoms product contains 98.0 mole% X and no B, and 85.5% of the X in the feed is recovered in this stream. The overhead product is fed to a second column. The overhead product from the second column contains 91.0% of the B in the feed to this column. The composition of this...

Q3 An equimolar binary liquid solution of benzene and toluene is to be separated by rectification in a plate column at atmospheric pressure. The feed is 60 mol percent vapor 40 mole percent liquid and flow rate of feed is 300 kmol/h. It is suggested to operate the column at a reflux ratio 1.7 times its minimum value. The top product should contain 95% benzene and 4 % of the benzene in the feed is loss in to the bottom...

A liquid mixture containing 45.0 % benzene (B) and 55.0 % toluene (T) by mass is fed to a distillation column. A product stream leaving the top of the column (the overhead product) contains 95.0 mole % B, and a bottom product stream contains 8.0 % of the benzene fed to the column (meaning that 92% of the benzene leaves with the overhead product). the volumetric flow rate of the feed stream is 2000 L/h and the specific gravity of...

The distillation column shown at the right is used to separate compound A from compound B in an adiabatic fashion. A liquid mixture of A and B is fed at a specified temperature into a distillation column (stream 1). At the top of the column, a vapor stream that is A-rich (stream 2) passes through a condenser that completely condenses the mixture. Half of this liquid leaves the condenser as the overhead product (stream 4), and half of the liquid...

A
distillation column is fed with a liquid mixture of 25.0 mole %
benzene, 30 % toluene and 45 % xylene. The bottom product from the
distillation column contains 97 mole % xylene and no benzene. The
other stream (upper one) contains 29 % benzene and it is fed to a
second distillation column. The upper...

A saturated liquid feed with a composition of 45 mole-% benzene and 55 mole-% toluene is distilled in a plate column at the rate of 250 kmol/h. Overhead product contains 97 mole-% benzene and the bottom product contains 5 mole-% benzene. A total condenser and a partial reboiler are used. The reflux ratio employed is 1.5 times the minimum, RD 1.5 RDmin Find the number of theoretical plates required for this separation, the heat duties of the condenser and reboiler....
Toluene + H2 → Benzene + CH4 Two streams enter the process. The first input stream...
Toluene + H2 → Benzene + CH4 Two streams enter the process. The first input stream is pure liquid toluene, which enters at a rate of 40 mol/s. The second input stream is a mixture of H2 (95 mole%) and CH4 (5 mole%). The flow rate of H2 in the second stream is equal to 200 mol/s. Two streams leave the process. The first output stream contains only liquid benzene (product) and toluene (unconverted reactant). The second output stream contains...

CONFIDENTIAL BKC/1617/BKF2343 QUESTION 1 An equimolar vapor mixture of n-pentane and n-hexane at 110°C and 1 atm is fed into a condenser at a rate of 200 L min When the feed is cooled and compressed in the condenser, some of the vapor is condensed. The products are separated and discharged in separate streams. The vapor and liquid products at the top and the bottom of the condenser are(in equilibrium at 60°C and pressure P mmHg. The vapor product stream...

Problem One [35 marks] A liquid mixture of benzene and toluene contains 55% benzene by mass, the rest is toluene is to be distilled continuously to produce two streams: the Overhead stream (v) in kg/hr and bottom stream (L.) in kg/hr. The overhead stream was analysed and was found to have 85% by mass benzene and the rest is toluene. The bottom stream was analysed and found to have 89.4% toluene and the rest is benzene. 1) Draw a flowchart...
