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...

The exit gas from an alcohol-fermenter consists of an air- CO. mixture containing 10 mol% CO, is to be absorbed in triethanolamine solution, containing 0.03 mol of CO, per mole of amine solution. The column is operated isothermally at 25 °C and Table 1 shows the equilibrium data for the system. The outlet gas contains 2.5 mol % of CO, and the absorption is carried out in a three theoretical plates Table 1: Equilibrium Data (mole CO./mole air) (mole CO/mole...

3. A liquid-liquid extraction process consists of two units, a mixer and a separator. One inlet stream to the mixer consists of two components, species-A and species-B. A stream of pure species-C is fed into the mixer to drive the extraction. The mixture is then fed to a separator where it is allowed to settle into two phases which are removed in separate streams. Each outlet stream contains all three species. The goal of the process is to produce an...

Please solve and I will rate answer
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...

please answer clearly
1 (Lecture LOI) 50 m3 of a 35-C gas mixture with composition 98 miole percent air(3), 2 mole percent toluene(1) is contacted with 400 kg of 35°C pure n-decane(2). The vapor-liquid system is allowed to come to equilibrium isothermally at 35 oC at a constant pressure of 1.0 atm. What are the final compositions of the liquid and vapor phases? You should neglect dissolution of air in the liquid, but you must account for evaporation of n-decane....

A mixture containing 42% benzene and 58% toluene by mass is fed to a distillation column. A second mixture is also fed to the distillation column and has a composition of 65% toluene and 35% acetone by mass. The flowrates of the mixtures are 2500 kg h1 and 1500 kg h1 respectively. An overhead distillate exit stream of 800 kg h-1 containing 23% acetone and a bottom exit stream of 25% benzene are produced. Determine the bottom exit flowrate and...

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...
