Chapter 9, Problem 9.19P

A CSTR is being operated at steady state. The cell growth follows the Monod growth law without inhibition. The exiting substrate and cell concentrations are measured as a function of the volumetric flow rate (represented as the dilution rate), and the results are shown below. Of course, measurements are not taken until steady state is achieved after each change in the flow rate. Neglect substrate consumption for maintenance and the death rate, and assume that Yp/c is zero. For run 4, the entering substrate concentration was 50 g/dm3 and the volumetric flow rate of the substrate was 2 dm3/h.

Problem 1 Marks: 60 Section: 1a): 30 marks, Section 1b):30 marks A laboratory scale fluidized bed is considered for studying a catalytic ozone decomposition. a) It is requested to derive model equations under the following assumptions: ■ Operation of the catalytic reactor under steady state conditions, There is no influence of thermal ozone decomposition reactions. The fluidized bed includes bubbles and dense phase. □ The dense phase can be simulated using a CSTR The fluidized bed bubbles contain catalyst particles and can be simulated as a DSTR (batch). □ The jets contain particles and can be simulated with a PFR. The influence of the freeboard has to be considered using a PFR model. The available catalytic reaction rate model is r (moles/gcat.s)= -k CA b) Same than on a) under unsteady state conditions, using an absorbable and reactive tracer. Note: A step-by step derivation of the model equations is required here. A quick answer will not do. Problem 2 Marks: 40 Section 2a: 30 marks,…
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.
