(a) What are the three main factors that might influence the selection of a particular reactor type for a given reaction? Explain each one of them. [6 Marks] ( (b) A new drug is being prototyped in a batch reactor. This drug is grown inside a cell as a by-product of the regular cellular processes. List two reasons why a batch reactor is suitable for this type of testing. Explain each one of them. [4 Marks] (c) Levenspiel plots are a good way to compare CSTR and PFR sizes. However, Levenspiel plots are seldom used to design 'real world' reactors. Provide two reasons why Levenspiel plots are seldom used to design real world reactors. Explain each one of them. [5 Marks] (d) You are employed in a small company that is trying to build a plant to produce Anychemical (A). You have sized all the pieces of equipment except the reactor(s). You cannot do the reactor sizing because you do not know the reaction rate data, nor do you have laboratory equipment to determine them. Time is of the essence and your boss wants you to estimate the reactor sizes and production rates, in three weeks' time. What would you do to obtain the desired information? Elaborate on how, when, and where would you do it. Also, who would possibly involve? [10 Marks]
