A gaseous stream containing 20.0 mole% ethanol and 80.0 mole% air is to be cooled from 60.0°C to 9.65°C in a condenser at the constant pressure of 1 atm to liquefy some of the ethanol. The gas stream entering the condenser has a pressure of 1.00 atm, flows at a rate of 10.0 mole/s and, at 60°C, is well above the saturation temperature (42.4°C). As a result of the cooling, 1.75 mole/s of liquid ethanol (Tbp = 78.5°C) leaves the...

#1 Acetone is to be removed from a nitrogen stream in a process. In the first step of the process, the gas is compressed from 1 atm to 4 atm. In the second step, the gas is cooled at constant pressure to a temperature of 5°C in a condenser. Some of the acetone condenses to liquid in the condenser and the remaining gas leaves the condenser saturated with acetone. The gas fed to the process enters at 40°C and 85%...

A gas mixture at 1.0 atm(abs) pressure containing air and CO2 is contacted in a simple mixer continuously with pure water at 295 K. The exit streams reach equilibrium. The inlet gas stream is 100 mol / h, containing 20 mol% CO2. The liquid flow rate is 300 mol/h Calculate the amounts and compositions of the 2 outlet phases. Assume that the water doesn't vaporize into the gas stream

A gas stream contains 18.0 mole% hexane and the remainder nitrogen. The stream flows to a condenser, where its temperature is reduced and some of the hexane is liquefied. The hexane mole fraction in the gas stream leaving the condenser is 0.0500. Liquid hexane condensate is recovered at a rate of 1.50 L/min. (a) What is the flow rate of the gas stream leaving the condenser in mol/min? (Hint : First calculate the molar flow rate of the condensate and...

#3 An absorber is to be used to remove acetone from air entering gas stream is 2 mole % acetone and enters at a rate of 40 kmol/hr. The water enters at a rate of 120 kmol hr. Both streams enter at 293 K and 1.4 atm pressure. We wish to remove 90 % of the entering acetone in this column. a. What is the minimum water flow to accomplish this separation? b. How many equilibrium stages would be required...

Terephthalic acid (TPA) is synthesized from -xylene (PX) in the
process C8H10 +302 – C8H6O4 +2H2O shown below. A fresh feed of pure
liquid PX combines with a recycle stream containing PX and a
solution (S) of a catalyst (a cobalt salt) in a solvent (methanol).
The combined stream, which contains S and PX in a 3:1 mass ratio,
is fed to a reactor in which 90% of the PX is converted to TPA. A
stream of air at 25...

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...
