Design Memo: You are tasked to design a 100000 metric tons per annum production plant of PX. The formation of PX is obtained from the following polymerisation reaction and also lead to the formation of wax (by-products). Oxygen is used as an initiator to this reaction at a concentration of 50ppm by weight Table 1: Boiling Points of components Table 2: Price of components Question 1: Using the heuristics of the destination code, classify the destination of products and impurity of the process based on the boiling point at the atmospheric pressure Question 2: Draw the block flow diagram of the process at level 2 (Input-Output level) and write the Mass Balance (MB) (write each process stream as a function of the conversion X of the limiting reactant). Question 3: Calculate the Economic Potential (EP) at input-Output level using your results in question 2 and prices in Table 2. Plot the EP versus X and decide on the value of the required conversion for your process to be financially sustainable (Justify). What is the value of the selectivity at the sustainable EP
