Case Study: Two AES exchangers in series have difficulty heating a process stream from 50°C to 90°C and cooling a hot stream from 110°C to 70°C at the same flow rate. Fortunately, an abandoned AES exchanger with four times the surface area of the two current exchangers is available, and it also has the correct material and sufficiently high design P&T, and it would fit on the plot space occupied by the present exchangers. Is replacement a good idea? Note: Show all elements of the design including explanations of: (a) assumptions made; (b) design calculations and; (c) necessary tables and figures for the calculations.
