B and contains90% of the B fed to the overall process. The bottom stream from the first column is fed to the second column which produces an overhead stream and a bottom stream. In the overhead stream for column 2, 60% of the total mass fed to column 2 exits as toluene. In the bottom stream for column 2, there are 3 parts toluene to every 4 parts of xylene. Draw a complete flowchart of the process and label all unknowns using the stream number designations shown in the provided table.
