For this problem, you are separating ethanol (more volatile) from water in three flash separators. The feed solution contains 100 mol/s with 30% ethanol by mole.The first flash unit is operated at 87 °F. The mole fractions of ethanol in the vapor phase and liquid phase are 0.42 and 0.09, respectively. The vapor stream leaving the first flash is then fed to a 2nd flash and the temperature is decreased to 83 °F.The mole fractions of the ethanol in the...

Methanol is produced by reacting CO and H2. A fresh feed stream containing CO and H2joins a recycle stream, and the combined stream is fed to a reactor. A portion of the methanol leaving the reactor is condensed, and the unconsumed CO and H2and uncondensed methanol are recycled. The stream going from the reactor to the condenser flows at a rate of 275 mol/min and contains 63.1 mole% H2, 27.4 mole% CO and 9.53 mole% CH3OH. The mole fraction of...

A mixture containing 240 kg ethanol and 301.6 Kg acetone is flashed at 1 atm. The feed rate is 541.6 kg/hr. a. Calculate the fractional vaporization required to obtain 66 mole % of ethanol in the liquid product stream leaving the bottom of the flash tank. b. Find the operating temperature which will achieve this separation. C. What are the compositions (mole %) in the product streams? d. Calculate the L/min of acetone in the vapor stream leaving the top...

Problem 4.80 Methanol Synthesis Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor. The fresh feed to the process contains 32.0 mol% CO 64.0 mol% H2 and 4.00 mol% N2: This stream is mixed with a recycle stream in a ratio of 10.00 mol recycle / mol fresh feed to produce th feed to the reactor, which contains 12.0 mol% N2 The reactor effluent goes to a condenser from which two streams emerge: a liquid product stream...

Ethanol is often used as a fuel additive, but to function in
most engines, the ethanol must be very pure and contain little
water. It is difficult to distill ethanol and water above 90 mole %
ethanol because at this concentration the vapor and the liquid
phases of this mixture have the same composition. To get around
this effect, benzene is often added to the mixture. The
distillation column then separates the mixture into a very nearly
pure ethanol stream,...

A gaseous stream containing 20.0 mole% ethanol and 80.0 mole% air is to be cooled from 60.0°C to 9.65°C in a condenser at the constant pressure of 1 atm to liquefy some of the ethanol. The gas stream entering the condenser has a pressure of 1.00 atm, flows at a rate of 10.0 mole/s and, at 60°C, is well above the saturation temperature (42.4°C). As a result of the cooling, 1.75 mole/s of liquid ethanol (Top = 78.5°C) leaves the...

Carbon monoxide and hydrogen react catalytically to produce methanol. CO + 2HZ rightarrow CH_3OH The fresh feed (100 moles/min) composition is 30 mole% carbon monoxide, a stoichiometric proportion of hydrogen and 10 mole% inert (nitrogen). A condenser (operates at 0 degree C and 1 atm) separates the unreacted gases and inert from the liquid product methanol. Part of the gas stream is recycled back into the main feed line to the reactor and the rest purged. The recycle ratio is...
