A dehumidifier is used to remove water from air, to deliver dehumidified air with a water content of 1.7 mol% H2O to a room.

The fresh air that needs to be dehumidified contains 4 mole% water.

A stream of the fresh air is combined with a recycle stream of previously dehumidified air and passed through the dehumidifier. The blended stream entering the dehumidifier contains 2.3 mole% H2O.   A fraction of the dehumidified air leaving the dehumidifier is recycled and the remainder is delivered to the room.

Taking 100 mol of dehumidified air delivered to the room as a basis of calculation, calculate the moles of fresh air feed, the recycle ratio, and moles of water condensed.

Show the full systematic mass balance.

Question Number II Ethanol (EtOH) can be produced by the hydration of ethylene, C2H4 + H2O ⇔ C2H5OH, at 300°C and high pressure with a phosphoric acid catalyst. Downstream of the reactor, a condenser is used to separate the product, which contains only EtOH and H2O, from a recycle stream that mixes with the fresh feed before entering the reactor. The fresh feed contains 30 mol% C2H4 and the remainder is steam. The single pass conversion is 20%. a. Draw...

Ethanol is produced commercially by hydration of ethylene and during this process a side reaction converts some the ethanol to diethyl ether (DEE). In one process, a fresh feed containing ethylene, non-condensable inerts, and water are mixed with a recycle stream. The combined stream is fed to the reactor and it contains 182 mol/min of ethylene. While the fresh feed contains 9 moles of ethylene per mole of inerts, after mixing with recycle stream, the mole ratio of inerts to...

Solvent S is used to extract a drug D from ground-up plant matter, but S must be recycled to cut costs. A fresh feed of pure S is joined with a recycle stream containing pure S at a different mass flow rate, and the combined stream is fed into an extractor, where it mixes with 1 kg/min D. The mixture of D and S leaving the extractor is fed to a separator. There are two streams leaving the separator. The...

A production facility heats various equipment using a network of heated air and water vapor lines. A boiler produces a 195.0 mol/hr stream consisting of 0.590 mol fraction of water and 0.410 mol fraction of air at 131.0°C and 5200.0 mmHg. The air and water vapor cool as the gases move away from the boiler, and steam traps collect and remove condensed water from the lines while the pressure remains constant. a) If a total of 65.6 mol/hr of condensed...

Ethylene oxides is produced by the catalytic oxidation of ethylene: C2H4 (g)+ (1/2)O2---> C2H4O (g) An undesired competing reaction is the combustion of ethylene to CO2. The feed to a reactor contains 2 mol C2H4/mol O2. The conversion and yield in the reactor are respectively 25% and 0.70 mol C2H4O produced/mol C2H4 consumed. A multiple-unit process separates the reactor outlet stream component: C2H4 and O2 are recycled to the reactor, C2H4O is sold, and CO2 and H2O are discarded. The...

Benzaldehyde is produced from toluene in the catalytic reaction C6H5CH3 + O2 ? C6H5CHO + H2O Dry air and toluene vapor are mixed and fed to the reactor at 350.0°F and 1 atm. Air is supplied in 100.0% excess. Of the toluene fed to the reactor, 13.0% reacts to form benzaldehyde and 0.100% reacts with oxygen to form CO2 and H2O. The product gases leave the reactor at 379°F and 1 atm. Water is circulated through a jacket surrounding the...
