*5.2. Electricity Consumption Pinch for All the Products Considered*

Case 2 presents a hypothetical case where for all products, the overall emission limit should not be exceeded. Only one electricity Pinch is obtained for the total electricity demand, as shown in Figure 6. The demand curve is the same as in Case 1, while the source curves for the Current case and Case 2 are now different. Both source curves are arranged in ascending order of emission factors for all the products combined. It can be seen that for slugs, only nuclear energy is used, while for evaporator panels, first nuclear energy is used, and later, also fossil energy to satisfy benchmark CO2 emissions. It should be noted that even here, fossil energy is the preferred source because it has the lowest cost; thus Cases 1 and 2 both exhibit the same cost, as shown in Table 7.
