60 points possible due Friday September 16, 2011 Grader: Alan Problem Statement: Four streams are to be cooled or heated with a ∆Tmin = 10°C. Find the minimum heating and cooling utilities and determine the pinch temperature. Design the corresponding heat exchanger network (HEN) for maximum energy recovery (MER) on both the hot and cold sides of the pinch. Calculate the required duty for each exchanger, identify any heat loops, and determine the minimum number of heat exchangers. s (°C)
