The production of ethylbenzene, a very popular industrial chemical, is carried out reacting benzene with ethylene in liquid phase. This reaction takes place in a series of reactors that involve multiple side reactions and intermediates. Ethylene, being the limiting reactant, is used up first and hence a considerable amount of benzene remains unreacted. From one of the reactors in the series, the exit stream is a mixture of this unreacted benzene (1), an intermediate – toluene (2), and the product ethyl benzene (3).
It is desirable to separate this liquid mixture before sending the components to the next series of reactors/process steps. So 100 mol/min of this mixture is flashed from 200 mm Hg and 50 °C to 100 mm Hg. If the mole fraction of benzene and toluene are 40% each when the mixture enters the flash distillation unit, determine if the mixture will flash completely, partially, or not at all. Assume ideal gas and ideal solution behavior for the vapor phase and liquid phase, respectively. If the mixture does flash partially, determine the composition and molar flow rates of the equilibrium streams exiting the reactor. Show all calculations by hand using your preferred method for solving simultaneous equations. Alternatively, you may use Solver (Excel) but this must be accompanied by a printout of a neatly formatted Excel sheet showing your equations and constraints.

The reaction between ethylene and hydrogen
bromide to form ethyl bromide is carried out in a continuous
reactors. The product stream is analyzed and is found to contain 50
mole % C2H5Br and 33.3 % HBr. The feed to the reactor contains only
ethylene and hydrogen bromide.
What would be the fractional conversion of the
limiting reactant and the percentage by which the other reactant is
said to be its excess.
