A pharmaceutical product is crystallized and washed with absolute ethanol. A 100 kg batch of product containing 10% ethanol by weight is to be dried to 0.1% ethanol by weight by passing 0.2 m3/min of 50�C nitrogen through the dryer. Estimate the rate (mol/min) that ethanol is removed from the crystals, assuming that ethanol exerts the same vapor pressure as if it were pure liquid. Based on this assumption, estimate the residence time for the crystals in the dryer. The dryer operates at 0.1 MPa and the vapor pressure of the pharmaceutical is negligible.

Absolute or 100% ethanol is produced from a mixture of 95%
ethanol and 5% water using the Keyes distillation process. A third
component, benzene, is added to lower the volatility of the
alcohol. Under these conditions, the overhead product is a
constat-boiling mixture of 18.5% ethanol, 7.4% water and 74.1%
benzene. Use the following data to calculate the volume of benzene
that should be fed to the still in order to produce 250 litres of
absolute ethanol: density of 100%...

Material Balance, Water removal
A 2000 kg batch of pharmaceutical-grade powder containing 7.5% by
weight water is dried in a drier.
After drying, 95% of the water that enters with the wet powder will
have been removed from the powder.
a. Draw a diagram of the process. Label ALL streams and indicate
stream compositions. Use proper
notations and units.
b. State a basis.
c. Perform an overall material balance and a material balance for
each species.
d. Calculate the final...

It costs a pharmaceutical company $75,000 to produce a
1,000-pound batch of a drug. The average yield from a batch is
unknown but the best case is 90% yield (that is, 900 pounds of good
drug will be produced), the most likely case is 85% yield, and the
worst case is 70% yield. The annual demand for the drug is unknown,
with the best case being 20,000 pounds, the most likely case 17,500
pounds, and the worst case 10,000 pounds....

(C2H5OH) is a common alcohol used in food, beverage and
pharmaceutical industries. The production of ethanol is through
fermentation of glucose (C6H12O6) in a reactor, which produces
ethanol and carbon dioxide (CO2). Unfortunately, glucose
fermentation also produces propenoic acid (C2H3CO2H) and water
(H2O) in a side reaction. A production engineer is designing a
glucose fermentation process that produces 46 000 kg of ethanol.
The conversion of glucose in this process is 80 % and the
selectivity of ethanol production to...

A television factory knows that 2% of their
televisions are defective. In a batch of 100 new televisions, 4 of
them are inspected at random. What is the probability that 1 of
them will be defective? What is the probability that they all turn
out to be defective?
