Consider the following two diagrams about the green separation of dimethylfuran. The masses are the numbers followed by the unit MTD (metric tonnes per day). The mass is moving from left to right except where it some of it flows through a loop/cycle. The diagram tracks the desired product dimethylfuran (DMF, green) and methylfuran (MF, red), butanol (BuOH, light blue), ethyl acetate (EtAc, grey), and water (dark blue). Which process top or bottom will have the greatest F-Factor? Explain why.
