Performance Analysis of Combined Cycle Power Plant Using Multi-Effect Distillation (MED) Desalination

Water is the most important substance on earth. Seawater distillation processes have a considerabletechnique suitable for producing large scale quantities of potable water. This process involves a wide rangeof technologies that yield access to different sources of water such as seawater, ground and surface water,and wastewater. Because of the reduction in access to fresh water in recent decades and the uncertainty in availabilityeffected by climate change, desalination is the critical process that ensure the future of humanity for fresh waterrequirement. Multi effect distillation process employs the same principles with multi-stage flash distillation but incontrasts, it occurs in a series of vessels (effects) and uses the principles of evaporation and condensation at reducedambient pressure. A dual-purpose desalination plant has a process that produces both power and fresh water usingoptimum thermal energy. It offers a considerable saving in energy usage. This paper focuses on the modelling andthermodynamic analysis of the "Multi-Effect Distillation" (MED) desalination installed in combined cycle powerplant and moreover the expected performance characteristics of the designed MED desalination plant has beendetermined.
