Mixture of acetone:toluene containing 40% acetone by mass, operating at atmospheric pressure with a capacity of 7,500 kg/h, as the main product.
95% by mass of acetone; the bottom product is 98% by mass of toluene.
project is requested. For each kilogram of the head product, 2.5 kg of rifax is used and the mixture to be distilled
Since it enters the distillation column as saturated steam;
a. Calculate the flow rates of the head and bottom products.
b. Calculate the amount of heat taken from the system in the condenser. (hF: 41.0 kcal/kg; H1: 130.0 kcal/kg; hW: 50.0 kcal/kg; hD:
15.0 kcal/kg)
c. Calculate the number of racks required for this distillation column and from which rack the feeding should be made.
d. If all other conditions remain the same, the amount of rifax applied per kilogram of head product is increased from 2.5 kg to 5 kg.
is removed and the mixture to be distilled is fed into the distillation column as a liquid at boiling point.
Explain the changes that will occur in the system by making calculations.
