A distillation column is a process unit that separates components based on their volatility. In the simplest columns, mixtures of components are fed to the column and two streams leave the column, a top stream that is rich in the more volatile component, and a bottom stream that is lean in the more volatile component. A liquid mixture containing 60.0% benzene and 40.0% toluene by moles is fed to a distillation column operated at steady state. The concentration in the top stream is 95 mole% benzene, and a bottom product stream contains 16% of the moles benzene fed to the column. Required:
a. Draw and fully label a flow chart for this process (include all knowns and unknowns).
b. Perform a degree of freedom analysis (do not include information given in part c of this problem).
c. If an inlet flow rate of 200 mol/h is used in the process, then determine the ratio of the molar flow rates of the two exiting streams (top stream/bottom stream).

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
