A gas stream containing 3mol% acetone, 2mol% water vapor, and remainder air is fed at a rate of 200 kmol/h to an adsorption column (Stream 1). Liquid water (Stream 2) is fed to the column, at 1/4 of the molar flow rate of the gas feed (Stream 1), with the purpose of recovering the acetone from the gas stream. 90% of the acetone in the feed is recovered in stream 4. All of the air leaves the column in stream 3. Completely label the diagram (using standard variable names!); assign variable names (with units) as needed, and perform a degree of freedom for the system, showing work below. Number of unknowns: names: Number of independent material balances: names: Number of additional equations: names: Degree of freedom = Calculate the total flow rate and molar composition of each stream. Show composition in mole %. Show your work, including all units in all equations, and write answers here. Stream 2: Stream 3: Stream 4
