In this study, exergy analysis of four different feed configurations of a multi-effect desalination with mechanical vapor compressor (MED-MVC) system is initially studied to identify the area of exergy destruction within system components and followed by an exergo-economic study. The feed configurations considered are forward feed (FF), backward feed (BF), parallel feed (PF) and parallel/cross feed (PCF). From the 1st law energy analysis, the PCF and FF configurations require less work to achieve equal distillate production compared to other two configurations. For instance, the specific power consumption (SPC) values are 30.1, 13.7, 23 and 13.9 kWh/m3 for the BF, FF, PF and PCF configurations, respectively. Changing the feed arrangement from BF to FF and PF to PCF at a constant compression ratio, the total fixed cost for the MED-MVC plant can be reduced by ~30% and 17%, respectively.
