Problem 2. (19 points) Read the Experimental section of the attached paper (Focile synthesis of PE-modified asphait by choin end-functionalization), in which asphalt, a commodity product, is modified to increase its performance. a) (15 points) Create a block flow diagram for this process following the process described in the manuscript (section 2.2 Synthesis of NPE and NPE-modified asphalt). Be sure to list major conditions and identify material flows. b) (2 points) Identify in your block flow diagram what steps are reaction, and which are separation/purification. c) ( 2 points) Discuss: does the paper provide enough information to simulate this process using a Process Simulator Software like ASPEN*? If not, what additional information do you require
