Q1- In order to produce main product D, A and B are fed to a sparged stirred tank reactor. Feeds enter the process at ambient conditions. Reactions occur in the gas phase at 500C. The single-pass conversion is very low for feed A. Both feeds are expensive, C is valuable byproduct. While boiling point of B,D and E are less than 110C, it is 95C for A. Boiling point of C is 120C and is highly soluble in water. A is also water soluble but gives azeotrope with water. D is very soluble in water but B and E are insoluble. A+B2D+CB+DE a) Suggest a block flow diagram for the production of D. Show the main units like reactors, separators (by giving the type of separation unit) and identify the recycle structure of the process, and also the contents (like A+B) of each stream on the stream lines. b) What separation process do you suggest for separating components? Justify your choices with one short sentence for each separation unit. c) Should you use any purge stream? Why or why not
