A mix fresh feed A at temperature 20 °C is heated to reaction temperature of 180 °C, before feed to reactor 1. Upon completion of the exothermic reaction, the products from reactor 1 are feed to reactor 2 and distillation column, respectively, in a pre-determined ratio. The product stream temperature of reactor 1 has to be reduced from 250 °C to 40 °C, prior to the separation process. On the other hand, a fresh feed B is heated from 140 °C to the reaction temperature of 230 °C and react with the product stream from reactor 1, in reactor 2, under endothermic condition. Subsequently, the product from reactor 2 is cooled from 200 °C to 80 °C, after the reaction. The chemical process is illustrated in Figure 3.1. The process stream data is shown in Table 3.1. a) Determine the pinch temperatures, minimum load of the hot utility and cold utility, respectively, using Problem Table Method by shifting both hot and cold temperatures and for minimum temperature difference of 10 °C.
