Water network revamp

In the water network revamping for increase in hydrocarbon load, two different values for increase in hydrocarbon load (50 and 100% for each process) are considered. In total, three different values of hydrocarbon load in each process unit (that is, normal, 50% increase, 100% increase) are useful to understand the shift of Pareto-optimal front with change in hydrocarbon load. Here, concentration of each contaminant in waste water is limited at 400 ppm (the same as in the original design).

Figure 12.7 Simultaneous minimization of fresh water flow rate and total flow rate through regeneration units, for water network design/revamping for different limits on contaminant concentrations in waste water (CC in WW).

Consider a smaller refinery water network problem by ignoring some processes in Table 12.1, and perform design, retrofitting and revamping via multi-objective optimization for two objectives, namely, fresh water consumption and total flow through the regeneration units, as in this chapter.
