You are required to design an absorption column. A gas stream is 92 mol% N2 and 8 mol% CO2. We wish to absorb the CO2 into water. The inlet water is pure and is at 25°C and 1 atm. If the liquid flow rate is 1.5 times the minimum liquid flow rate, how many equilibrium stages are required to absorb 65% of the CO2? The system is considered concentrated. Choose a basis of 100 mol/h of entering gas. Find the number of stages required. Equilibrium is found using Henry's constant, y=1640x.

We aim to absorb 99.7% of ammonia from a gas stream containing 0.013 mole fraction of NH3. A counter-current packed bed column is used and the inlet liquid is pure water. We wish to operate at (L/G) = 15 (L/G)min and 20 °C. If the slope of the equilibrium line is 2.5, and HOy= 0.2 m, calculate: The mole fraction of ammonia at the outlet gas. The mole fraction of ammonia at the outlet liquid. The packing height required. TABLE...

A gas stream which is 70.0 mol% CO2 and 30.0 mol% N2 is flowing at a rate of 225 kilograms per minute. What is the volumetric flow rate of this gas mixture, in units of cubic meters per minute, if the gauge pressure is 1.50 bar and the temperature is 300.0 Kelvin? * I know the answer is 95.4 cubic meters per minute, I need to know the steps of how to solve the problem. Thanks!

A gas stream contains 4.0 mol % NH3 and its ammonia content is reduced to 0.5 mol % in a packed absorption tower at 293 K and 101300 Pa. The inlet pure water flow is 68.0 kgmol/h and total inlet gas flow is 57.8 kgmol/h. The tower diameter is 0.747 m. The film mass-transfer coefficients are k’ya=0.0739 kgmol/s.m3 .molfrac and k’xa= 0.169 kgmol/s.m3 .molfrac. Using the design methods for dilute gas mixtures, (a) Calculate the tower height using k’ya. (b)...

A liquid stream has a flow rate of 100 mol/min and contains 25 mol% Stanzium and 75 mol% water. Stanzium is foul and disgusting and nobody wants that stuff in their water, so an extraction process is used to purify the water. The liquid enters the extraction unit, as does 400 mol/min of a solvent stream, which contains 98 mol% hexane and 2 mol% Stanzium. The water and hexane are completely immiscible, though the Stanzium is soluble in both. The...

A gas has a dry-basis composition of 9 mol% CO, 10mol% CO2, 1mol% O2, and 80mol% N2. The gas temperature and pressure are 600°C and 1 atm and it has a dew point temperature of 50°C (due tothe presence of water). The gas must be cooled to 400°C. This is accomplished by spraying liquid water at 20°C into the gas.The liquid water evaporates and leaves the cooler with the gas as water vapour. Calculate the required volumetric flow rate of...

Separations Question It is desired to recover atleast 95% of ethanol from a mixture of ethanol and carbon dioxide (containing 98 % CO2 and 2 % ethanol) by scrubbing the vapor mixture with pure water. Assume equilibrium relation Y = 0.57 X. The gas stream enters the absorption column at 180 kmol/hour (V’) at 120 kPa (P) and 27 °C (T). The carrier gas may be considered insoluble in the solvent and the solvent may be considered nonvolatile. Assume dilute...
