A liquid mixture of benzene and toluene containing 52.0 wt% benzene at 100.0 °C and pressure Po atm is fed at a rate of 32.5 m³/h into a heated flash tank maintained at a pressure Ptank << Po- When the feed is exposed to the reduced pressure in this unit, a portion of it evaporates. The liquid and vapor product streams are in equilibrium at 75.0 °C and Ptank The liquid product contains 43.9 mole % benzene. When carrying out the requested calculations, assume volume additivity of liquid benzene and toluene, use Raoult's law and the Antoine equation where necessary, and negelect the effect of pressure on enthalpy. Physical Property Tables Feed Calculate the molar flow rate (mol/s) and molar composition (component mole fractions) of the feed stream. Then calculate the minimum value of Po(atm) needed to keep the feed stream in the liquid state until it enters the flash tank.
