Example 12-3. Graphical analysis for more concentrated absorber A gas strearn is 90 mol% N2 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...
2. A gas mixture at 1.0 atm pressure containing air and solute A is contacted in a single stage mixer continuously with pure water at 30 °C. The two exit gas and liquid streams reach equilibrium. The inlet gas flow rate is 100 kg mol/h, with a mole fraction of A being 0.20. It is desired that the exiting gas contain an A mole fraction of 0.01. Calculate the flow rate of liquid required to achieve this separation. Assume that...
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
To absorb CH4 contained in nitrogen by using liquid ammonia. The
inlet gas speed is 100 kmol/h, and the mole fraction of CH4 is
0.2%. It is intended to eliminate 98% of CH4 entering by using pure
liquid ammonia as an absorbent. The absorption process operates at
253.2 K, 175 atm, where the equilibrium information of methane is
yCH4 = 20 × xCH4. The total flow rate of gases and liquids is
assumed to be constant within the absorption tower,...
Heat Exchanger V1 = 8.80 L/s acetone n2 mol/s acetone P2 = 1 atm Saturated acetone vapor enters a heat exchanger at a rate of 8.80 L/s at 1 atm, and emerges from the heat exchanger as a saturated liquid at the same pressure. Water at 1 atm enters the heat exchanger at 11.5°C and at a rate of 8.65 mol/s. Assume that the heat exchanger operates adiabatically with respect to its surroundings. Calculate the temperature of exiting water by...
Problem 9.26 Benzaldehyde Production Benzaldehyde is produced from toluene in the catalytic reaction CH.CH3 + O2 + CHECHO + H20 Dry air and toluene vapor are mixed and fed to the reactor at 350.0 °F and 1 atm. Air is supplied in 200.0 % excess. Of the toluene fed to the reactor, 13.0 % reacts to form benzaldehyde and 1.70 % reacts with oxygen to form CO2 and H20. The product gases leave the reactor at 379 °F and 1...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
