Textbook Question
Chapter 8, Problem 8.11P
Chlorine gas is to be heated front 120°C and 1 atm to 180°C.
- Calculate the heat input (kW) required to heat a stream of the gas flowing at 15.0kmol/min at constant pressure.
- Calculate the heat input (kJ) required to raise the temperature of 15.0 kmol of chlorine in a closed rigid vessel from 120°C and 1 atm to 180°C. (Suggestion: Evaluate AC directly from the result of the first calculation, so that you do not have to perform another integration.) What is the physical significance of the numerical difference between the values calculated in Parts (a) and (b)?
- To accomplish the heating of Part (b), you would actually have to supply an amount of heat to the vessel greater than the amount calculated. Why?

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.

- Bacterial production of alginate Azotobacter vinelandii is investigated for production of alginate from sucrose. In a continuous fermenter at 28°C with ammonia as nitrogen source, the yield of alginate was found to be 4 g g^−1 oxygen consumed. It is planned to produce alginate at a rate of 5 kg h^−1. Since the viscosity of alginate in aqueous solution is considerable, energy input due to mixing the broth cannot be neglected. The fermenter is equipped with a flat-blade disc turbine; at a satisfactory mixing speed and air flow rate, the power requirements are estimated at 1.5 kW. Calculate the cooling requirements.arrow_forwardPreheating nutrient medium Steam is used to heat nutrient medium in a continuous-flow process. Saturated steam at 150°C enters a coil on the outside of the heating vessel and is completely condensed. Liquid medium enters the vessel at 15°C and leaves at 44°C. Heat losses from the jacket to the surroundings are estimated as 0.22 kW.
