efer attachment) (a) Sketch a process flow diagram (PFD) of the process described above.
A small plant is designed for conversion of component A to a target product of component B. Component A is fed from a holding tank where it is mixed with recycled component A. The Component A is pumped and heated to reaction temperature before entering the reactor. The reaction of component A does not require a catalyst, since it is initiated at high temperatures. The reactor is simply a vessel with inert packing to promote radial mixing. The reaction is quenched and main products formed consist of component B and C while side reaction of some component B has produced component D. There is one holding vessels is used to hold reaction products and remove component D. This allows a continuous flow of other components into distillation column (column 1) where the component A is separated (as bottom product) and recycled, and another distillation column (column 2) was used to purify component B (less volatile) from the component C. The recycle component A will be cooled and drive to the holding tank as mention earlier. The important conditions for equipment described above are summarized in Table 1 below.

(a) Sketch a process flow diagram (PFD) of the process described above.
(b) Then, construct process conditions matrix (PCM) for the process and determine all conditions of special concern. For each condition of special concern identified, suggest at least one reason why such a condition was used and process alternative to eliminate the condition.
