A B S T R AC TPerformance evaluation is presented for fl ue gas desulfurization (FGD), humidifi cation and dehumidifi cation desalination (HDD) of fl ue gases emitted from power plants. The proposed system is based on use of seawater for SO 2 absorption and removal from the fl ue gases. The FGD and HDD processes are separated in order to achieve the highest possible effi ciency. This is because FGD requires low temperatures to achieve high rates of absorption and removal of SO 2 . On the other hand, HDD requires higher temperatures to provide suffi cient temperature difference and driving force for humidifi cation and dehumidifi cation. Analysis of both systems is applied to the emission rate data of power plants in Kuwait. The design results of the seawater SO 2 absorption column showed variations in the column height between 8.1-12.6 m as the power plant capacity was increased from 244-4173 MW. Analysis of the HDD system show that it might not be the optimum desalination alternative because of its limited production capacity. However, the process layout is simple and can be formed of two packed columns for humidifi cation and dehumidifi cation, which requires a small capital when compared to conventional thermal or membrane desalination.

“…Narayan et al developed a comprehensive model for the HDD system, which included mass, energy, and entropy balances [10][11][12][13][14][15][16]. Several novel cycles were proposed by the authors and showed that these cycles provide gain output ratio in excess of 5, which is much higher than conventional HDD.…”

The desalination of brackish water by solar distillation is a widely used operation in arid region, at the scale of a small village or even a family. The combinations of desalination and solar technologies become very economic process especially in arid zones in the southwest of Algeria. It is principally an economic question.The objectives of our study are testing the feasibility of solar distillation in desalinating water. The lack of drinking water and the scarcity of its natural resources caused both by the drought and the over exploitation of groundwater is becoming a major problem that threatens the lives of the inhabitants in several sub-Saharan regions.The drinking water in the south of Algeria is very concentrate on salts. The distilled water after solar distillation gives good removal yield of the global mineralization (99% of total dissolved ions).
