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...

A packed tower is to be used to remove 90% of the ammonia from an air stream containing of 5% of ammonia by volume. The feed gas rate is 100 lb mol/hr at 20 °C and 1 atm. Water at 90 lb mol/hr containing no ammonia is used as a solvent and the packing is 1-inch Raschig rings. Assume the tower is isothermal at 20 °C. It is to operate a 60% of flooding. In addition, for this system m...

1. An existing absorption tower contains the equivalent of 3.0 theoretical trays and is being used to absorb SO2 from air by pure water at 293 K and 1.0 atm. The entering gas contains 15 mol % SO2 and the inlet air flow rate is 150 kg inert air/h-m2. The entering water rate is 6000 kg inert air/h m2. Calculate the composition of the outlet gas. (Hint:...

(30 points) A packed tower uses an organic amine to absorb carbon dioxide. The entering gas contains 1.26 mol % CO2 and is to leave with only 0.04 mol % CO2. The amine enters pure, without CO2. If the amine leaving is in equilibrium with the entering gas (which it doesnt), it would contain 0.80 mol % CO2. The gas flow is 2.3 molls, the liquid flow is 4.8 mol/s, the tower's diameter is 40 cm and Kya is 5x10...

A chemical plant produces an ammonia-rich waste gas that cannot be released as-is into the environment. One method to reduce the ammonia concentration in the waste gas is to bubble the waste gas through a liquid solvent. Components of the gas that are highly soluble, like ammonia, will dissolve into the liquid phase. Water is an appropriate liquid solvent for this process. The chemical plant produces 105.0 m^3/hr of waste gas (rho = 0.0407 mol/L) initially having a mole fraction...
