Given the two process streams below, determine the best scheme for

heat integration. Determine the amount of heat that will have to be supplied from a

hot utility $($e$.$g$.,$ steam$)$ and how much cooling from a cold utility $($e$.$g$.,$ cooling

water$).$ What must the temperatures of the utilities be$?$ What are the benefits of

this heat integration? Maintain a $10C$ minimum approach temperature.
