The rapid growth in the world’s population, the high demands-per-capita modern way of life in the industrialised countries, poor resource management and increasing pollution have led to problems associated with wafer supplies. ’Fresh’ potable ground-water is being consumed faster than it is being replenished naturally and there is a frequent lack of adequate provision of pure water for domestic, industrial and agricultural purposes, especially in arid areas. Desalination seems to be the only viable answer to freshwater shortages in some parts of the world. However, saline-water processing can be expensive and energy intensive. Thus, an integrated combined-cycle heat-and-power as well as seawater desalination plant is proposed and its performance assessed.
