A team of consultants has extracted the stream data in Table $2$ for a heat integration study.

Table $2$: Stream data extracted for heat integration study.

a$.$ Target the maximum energy recovery potential assuming DTmin of $10C.$ What is the new minimum hot and cold utility

target?

b$.$ Based on your result in $($a$),$ design a heat exchanger network that achieves the maximum energy recovery target by

using a grid diagram. Label all the heat exchanger duty, as well as the inlet and outlet temperature for all heat exchangers.

c$.$ Determine the percentage of cold and hot utility savings as compared to no heat integration.

d$.$ Assuming the company decided to proceed with detailed design analysis if the utility savings is more than $50\%,$ advice

the company if they should proceed or not?CaCa
