Question statement: For the four stream problem given below, perform the following heat recovery and integration steps and discuss your results (for each step): ATmin= 10 C Stream No. 1 2 Supply Temp. (c) Target Temp. (C) 720 320 520 220 300 900 200 550 Heat Capacity Flowrate (MW/K) 0.045 0.04 0.043 0.02 3 4 1. On the attached pinch analysis diagram show the following (and write values below): [Highlight the Recovery Area i a. Amount of potential energy recovery:-- the Plot) b. Minimum heating requirement:- c. Minimum cooling requirement:-- d. Location of the pinch point on hot/cold temperature scales:- 2. Following the problem table method (cascade), show the energy balance around interval 1 and 2 3. Using the attached grid diagram, construct a Heat Exchanger Network (HEN) for (above pinch area ONLY) maximum energy recovery for these streams showing the extra utilities needed (AT min must be checked)
