The temperature interval diagram for a process is shown in Figure P15.16. For this process do the following:

• Compute the missing values of ṁC_p for Streams 2 and 3, the missing Q values for temperature intervals B, C, and E, and the total of all intervals.
• Calculate the minimum hot and cold utility loads for this process subject to a minimum approach temperature of 20°C.
• Calculate the pinch temperatures for this process. You may assume that there is only one hot and one cold utility available.
• Calculate the minimum number of exchangers needed for the minimum energy case for above and below the pinch.
• Design the MUMNE network for the process.
