QUESTION 1 Consider a process flowsheet in Figure 1, where the duties required for each heat exchanger are in kW, and the source and target stream temperatures are shown in Table 1. a) Based on the flowsheet in Flgure 1,107kW is to be removed by cooling water and 189 kW is to be provided by steam. Prove that this design does not meet MER targets for Tm=10C. (13 marks) b) Design a HEN to meet MER targets for Tmin=10C. (15 marks) c) Design a HEN to meet MER targets using Tmin=50C. Compare your answer with HEN design in (b) and expiain the importance of ATain.
