2. A mixture of 60 wt% benzene, 35% toluene, and 5% naphthalene is being distilled. The distillate product should be 99.5 wt% benzene. Also, 99% of benzene fed should be recovered in the distillate, Determine/calculate: a. Distillate and bottom product flow rates (D and B) per 1 kg of feed b. compositions of distillate and bottom product c. fraction of toluene fed that is recovered in the bottom product

(a)  Distillate (D) = 0.597 kg

    Bottom product (B) = 0.403 kg

(b) Compositions of distillate  product:

     Benzene = 0.995

     Toluene = 0.05

   Compositions of bottom product:

    Benzene = 0.0149

    Naphthalene = 0.1241

    Toluene = 0.8610

(c) Fraction of toluene fed that is recovered in the bottom product = 99.14%

Explanation:

See the attached file for the calculation

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
