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...

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....

A tray tower is designed to absorb acetone from air stream using pure water at 293 K and 101.3 kPa. The inlet air flow rate is 483.33 kg/min (MW air = 29) and it contains 5 mol % of acetone. It is desired to remove 95 % of the acetone from air stream. The equilibrium relationship for this dilute stream is given by the equation of y= 1.186 x. * All the solutions should be presented in the unit of...

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...

A gas stream containing acetone in air flows from a solvent recovery unit at a rate of 142 L/s at 150°C and 1.3 atm. The stream flows into a condenser which condenses most of the acetone, and the liquid and gas outlet streams are in equilibrium at -18°C and 5.0atm. Shaft work is delivered to the system at a rate of 25.2kW to achieve the compression from 1.3 atm to 5.0 atm. To...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
