An equimolar liquid mixture of benzene and toluene at 10C is
fed continuously to a vessel in which mixture is heated to 50C. The
liquid product is 40 mole%B and the vapor product is 68.4% B. How
much heat must be transferred to the mixture per mol of
feed?

A vessel contains a mixture of equimolar liquid benzene and
liquid toluene that is in equilibrium with their vapors and air.
The temperature of the mixture is 40 degrees celsius. The mole
fraction of air in the vapor phase is .6 or 60%. What is the total
pressure and the mole fraction of benzene in the vapor phase?

A benzene/toluene liquid mixture consisting of 31 mole% benzene
is fed to a reboiler, where 1250 KW of heat is provided causing the
mixture to partially vaporize. The vapor output has a flowrate of
80 kmol/hr and consists of 40 mole% benzene. The liquid output has
a flowrate of 100 kmol/hr. The two output streams are in
equilibrium and exit the reboiler at 130 oC. Determine the
temperature of the feed stream. Neglect the effect of pressure and
consider the...

A liquid mixture of benzene-toluene is to be distilled in a
fractionating tower at 101.3 kPa pressure. The feed of 100 kg mol/h
is liquid, containing 45 mol benzene and 55 mol% toluene, and
enters at 327.6 K. A distillate containing 95 mol benzene and 5 mol
toluene and a bottoms containing 10 mol benzene and 90 mol toluene
are to be obtained. The reflux ratio R is 4: 1. Determine the kg
moles per hour distillate, kg moles per...

A liquid mixture of
benzene and toluene is contained in a closed vessel at 60°C. The
only other component in the system is nitrogen gas which is used to
pressurize the system to 1 atm total pressure (absolute). The
liquid is 70 mole% benzene and 30 mole% toluene, and the
N2 is considered non-condensable (i.e., the liquid mole
fraction of nitrogen is zero). Consider the mixture to be ideal,
and determine the vapor mole fractions of the three components.

A saturated liquid feed composed of 30 % mol Benzene (B), 30 %
mol Toluene (T) and 40 % mol p-Xylene (X) is separated by an
isobaric column operating at 1 atm. The feed flow rate is 1
kmol/hr. Toluene is the light key with a mole fraction in the
bottom stream equal to 0.1. The heavy key has a mole fraction in
the distillate stream equal to 0.05.
