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...

You wish to remove solute Q from a heavy oil stream by stripping the oil with air. The stripper is expected to operate at 60°C and 2.2 atm pressure. At this temperature and pressure the oil can be considered to be nonvolatile and the air is insoluble in the oil. The inlet liquid flows at 100 kgmole/hr (total flow) and is 20 mole% Q. You wish to reduce the concentration of Q in the oil to 1 mole% Q. The...

A gas stream containing acetone in air flows from a solvent recovery unit at a rate of 142 L/s at 150°C and 1.3 atm. The stream flows into a condenser which condenses most of the acetone, and the liquid and gas outlet streams are in equilibrium at -18°C and 5.0atm. Shaft work is delivered to the system at a rate of 25.2kW to achieve the compression from 1.3 atm to 5.0 atm. To...

The heavier component has to be removed from a gas stream by absorption. The absorption column operates at 2 550 kPa. The entering liquid is high molecular mass oil which contains 0.45% of the heaviest component but none of the lighter components. The total molar flowrate of the oil entering the absorber is 150 kmol/hr. The effluent gas that enters the absorber at 800 kmolhr contains 20 mol% C, 46 mol% C2, 30 mol% C3, 4 mol% n-C4. There are...

Example 12-3. Graphical analysis for more concentrated absorber A gas strearn is 90 mol% N2 and 10 mol% CO2. We wish to absorb the CO2 into water. The inlet water is pure and is at 5°C. Because of cooling coils, operation can be assumed to be isothermal Operation is at 10 atm If the liquid flow rate is 1.5 times the minimum liquid flow rate, how many equilibrium stages are required to absorb 92% of the CO2? Choose a basis...

Problem 3 G1-1.665 kmol/h of a binary gas mixture containing ammonia (vi-35%, molar basis) and air enter an absorption column operating at 1 atm and 20 °C, where a liquid mixture of water and ammonia (x-2.11%, molar basis) is used to remove 90% of the ammonia from the gas stream. Equilibrium data for this system is given in the table below: (kg NH;) / (100 kg Partial pressure of NH H2O) Mole fraction of NHs in Mole fraction of NHs...

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 tray tower is to be used to remove 99% of ammonia from an entering gas stream containing 15 mol% ammonia at 30 oC and 101.3 kPa. The entering pure water flow rate is 188 kg H2O/h.m2 and the inert gas flow rate is 130 kg inert gas/h.m2. Calculate; a. The minimum water flow rate b. Estimate the number of theoretical trays nedded.

#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%...
