2500 kg/hr of a mixture containing equal parts by mass of benzene and toluene are distilled. The flow rate of the overhead product stream is 988 kg/hr , and the bottom stream contains 17.03 wt% benzene. Draw and label a flowchart of the process. Then calculate the mass and mole fractions of benzene and the molar flow rates of benzene and toluene (mol/hr) in the overhead product stream.
The density of liquid oxygen at its boiling point is 1.14kg/L , and its heat of vaporization is 213kJ/kg. How much energy in joules would be absorbed by 4.0 L of liquid oxygen as it vaporized.
