“…Further integrating the process intensification technique into the existing MED process model amplifies the level of mathematical complexity, making the use of the NSGA-II optimization algorithm for the intensified MED process model more difficult. There are a few studies on MOO using NSGA-II reported in the open literature for the MED system. − However, most of them have commonly focused on the improvement of the energetic, economic, and thermodynamic performance of the MED/MED-TVC process. With this current status on the MOO of MED, two major issues are identified.…”

This work proposes a carbon-neutral desalination process. For this, at first a rigorous theoretical framework for multieffect desalination coupled with a thermal vapor compressor (MED-TVC) is developed to validate with the data set of a plant operated in Libya and to show the outperformance over an existing model. A mechanical vapor compressor (MVC) is proposed to integrate with MED, and the hot brine and distillate withdrawn from that MED are employed for feed preheating. A multiobjective genetic algorithm -based optimizer is formulated with three conflicting objectives, namely, productivity, CO 2 emission, and production cost that includes carbon tax. The proposed MED-MVC outperforms MED-TVC in terms of all of those performance metrics. Subsequently, we move to transform this MED-MVC process to a carbon-neutral unit by introducing solar energy to generate makeup steam and electricity. This innovative sustainable zeroemission desalination process secures higher productivity at a lower cost than the existing MED-TVC plant scenario.
