In a gas absorption tower, acetone is absorbed from its mixture with air using a nonvolatile
absorption oil. 100 mol/h of gas mixture enter the bottom of the column contains 30 mol%
acetone while 261.9 mol/h oil enter the top of the column. The exiting gas stream is to
contain 1.3 mol% acetone.
a) Determine molar flow rate of the exiting gas and exiting liquid streams.

b) Determine number of stages required for the above process.

By means of a plate column, acetone is absorbed from its mixture with air in a non-volatile absorption oil. The entering gas contains 20 mole percent acetone, and the entering oil is acetone-free. Of the acetone in the air, 98.5 percent is to be absorbed, and the concentration of the liquor at the bottom of the tower is to contain 8 mole percent acetone. The equilibrium relationship is ye=1.85xe. Plot the operating line and determine the minimum number of stages....

In an absorption tower (or absorber), a gas is contacted with a liquid such that one or more components in the gas is transferred in the liquid. A stripping tower (stripper) also involves a gas contacting a liquid but components are transferred from the liquid into the gas. A process consisting of an absorber and a stripper is used to separate the components of a gas containing 35.0 mole% CO2 and the balance CH4. This gas is fed to the...

Gas mixture containing H2S and air from a petroleum distillation column, has its concentration of H2S reduced from 4.0 mol% to 0.1 mol% by scrubbing with a triethanolamine-water solvent in a countercurrent tower, operating at 300 K and at atmospheric pressure. H2S is soluble in such a solution and the equilibrium relation may be taken as Ye = 2.2X. The solvent enters the tower free of H2S and leaves containing 0.015 kmol of H2S/kmol of solvent. The overall coefficient for...

A liquid mixture contains 50 wt% ethanol (E), '10 wt% of a dissolved solute (S) and the balance is water (W). A stream of this mixture F, is fed to a continuous distillation column operating at a steady state. Two streams emerge from the column as the top product, P and the bottom waste Q, respectively. The column design class for the product streams is to have equal mass flow rate, and for the top product stream, P is to...

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...
