The value of f that maximizes the operational profit of the plant is to be stated. The optimum conversion of A that is fed to the plant is to be stated. Concept introduction: The full form of CSTR is Continuous-Stirred Tank Reactor. This reactor has its application in the industrial processes. This reactor is actually used for liquid-phase reactions. The conversion, X can be defined as the moles of any species A that are reacted per mole of A fed in the reactor.

Penicillin process Penicillium chrysogenum is used to produce penicillin in a 90,000-litre fermenter. The volumetric rate of oxygen uptake by the cells ranges from 0.45 to 0.85 mmol l^−1 min^−1 depending on time during the culture. Power input by stirring is 2.9 W l^−1. Estimate the cooling requirements.

Production of bakers’ yeast Bakers’ yeast is produced in a 50,000-litre fermenter under aerobic conditions. The carbon substrate is sucrose; ammonia is provided as the nitrogen source. The average biomass composition is CH_1.83O_0.55N_0.17 with 5% ash. Under conditions supporting efficient growth, biomass is the only major product and the biomass yield from sucrose is 0.5 g g^−1. If the specific growth rate is 0.45 h^−1, estimate the rate of heat removal required to maintain constant temperature in the fermenter when the yeast concentration is 10 g l^−1.
