Q$1.(45$ pts$)$ Below is a simplified version of a process block diagram for an acetic acid producing

plant. Also, a table is provided that shows relevant information for the process hot and cold

streams. Determine the minimum annual heating and cooling utility targets for the process. You

may assume $T$ as $10C.$

a$.(20$ pts$)$ By using algebraic $($cascade$)$ method

b$.(15$ pts$)$ By using graphical method

c$.(10$ pts$)$ By using linear program coding methods $($just write the code$)$

Stream Descriptions:

Fresh acetone going in the system.
