(c) A heat recovery system has the process stream data as listed in Table 1. (i) Conduct problem table analysis to look for the minimum energy requirements and the pinch temperatures of a grassroot model using ATmin = 10°C. [4 marks] (ii) Design a heat recovery network with the minimum number of units. Hint: You may need to split a stream below the pinch. [5 marks] (iii) Evolve the design to eliminate stream split(s) below the pinch while maintaining the minimum number of units in (i) by slightly relaxing the minimum temperature approach.
