2.17.6: Two distillation columns with ethanol, butanol, and propanol.
Two distillation columns, which are overseen by engineers Gianna and Peter, separate three components. A liquid mixture enters the first column at 536 kg/s and contains 35.0 mass % ethanol (C₂H5OH), 15.0 mass % propanol (C3 H7 OH), and the balance butanol (C4 H9 OH). The bottom product stream of the first column contains 93.1 mass % B and no E, and 95.1% of the B in the feed stream is recovered in the bottom product stream. The overhead product of the first column is used as the feed stream to the second column. The overhead product from the second column contains 92.1% of the E inthe feed to this column. The composition of the overhead product stream is 91.5 mass % E and the balance P. Find the component mass flow rates (kg/s) exiting in the overhead product of the first distillation column. Stream numbering is same as PFD for question 1.

2.17.7: Two distillation columns with three components.
A pair of distillation columns are being monitored by Beatrix and Enrico. Benzene (B), toluene (T), and xylene (X) are fed to the first distillation column. The overhead product of the first column contains only benzene and toluene. Toluene is fed to the first column at 1020 mol/hr while 74.4% of the benzene fed to the first column ends up in the overhead product. The stream exiting the bottom of the first column has a flow rate of 1590 mol/hr with 28.5 mol % benzene, 23.8 mol% toluene, and the rest xylene. The bottoms product from the first column is fed to a second distillation column. Pure xylene exits the bottom of the second column while the overhead product contains only benzene and toluene. Determine the following three unknowns.
Flow rate of xylene exiting the second column = Ex: 515 mol/hr
Mole fraction of toluene exiting the second column = Ex: 0.582
Flow rate of benzene exiting the overhead product of the first column = Ex: 1.50E mol/hr

2.17.8: Making orange juice concentrate.
Maximus and Theodora are optimizing a steady state processing making orange juice concentrate. A stream of oranges (0) and a stream of water (W, H₂O) enter a juicing machine. The exit stream from the juicing machine contains 55.8 kg/hr orange juice (OJ, MW = 108), 21.3 kg/hr pulp solids (PS), and 43.5 kg/hr water. The exit stream from the juicing machine enters a filter. The filter removes all of the pulp solids and 20.2% of the water entering the filter as one exiting stream. The other stream exiting the filter contains water and orange juice. The water/orange juice mixture is finally sent to an evaporator to produce a concentrate stream (80.1 wt% orange juice and the balance water) and a stream of pure water. The pure water is recycled, mixed with a fresh stream of pure water, and fed into the juicing machine. Determine the following three unknowns.
Mole fraction of orange juice in the concentrate stream =Ex: 0.309
Mass flow rate of water entering the evaporator =Ex: 30.9 kg/hr
Mass flow rate of water entering the overall system =Ex: 16.8 kg/hr

2.17.9: Preheater and distillation column.
A preheater and distillation column are maintained by engineers Marcella and Julius. A stream of pure acetone (A, C3H6O) and a stream containing acetone, ethanol (E, C2H5OH), and butanol (B, C4H, OH)entering the preheater. One stream exits the preheater containing 144 mol/min butanol, some acetone,and some ethanol; the mole fractions of butanol and ethanol are 0.209 and 0.412, respectively. The stream of pure acetone entering the preheater is 2.42 times larger than the component flow rate of acetone in the other stream entering the preheater. The stream exiting the preheater enters a distillation column, and all of the entering butanol exits in the bottom product stream. The recoveries in the overhead product, which is defined and the ratio of component flow rate exiting to component flow rate entering the distillation column, of acetone and ethanol are 83.1% and 59.2%, respectively. Determine the following three unknowns.

Question 52870
Chemical Process Calculations
Engineers Sophia and Giles are modifying a process to make concentrated apple cider starting from a slurry - a slurry is a mixture of solids in a liquid that can normally be pumped. A slurry made with apple shaving a mass fraction of 0.422 and the balance water is fed to a juicer at a rate of 26.2 kg/min. Seventy percent of the apples entering the juicer leave as part of the solid waste stream (containing apples and water). The primary product from the juicer is cider (35.3 wt% apples and 64.7 wt% water). The cider is sent to an evaporator where concentrate - apple concentration increases to 51.5 wt% - is produced along with a stream of pure water that is recycled. The pure water stream leaving the evaporator is mixed with fresh water entering the process. The combined water stream mixes with pristine apples entering the process to create the slurry. Determine the following three unknowns.
Mass fraction of apple in the solid waste = Ex: 0.632
Total flow rate of the concentrate = Ex: 8.82 kg/min
Flow rate of pure water entering the overall system = Ex: 8.95kg/min
