Abstract
An increase in demand for water, resulting from population growth and the need to augment food production, puts pressure on the limited available water resources, especially in areas of physical water scarcity. One alternative to offset the water demand and many of the negative impacts of running desalination plants is to combine Concentrating Solar Power (CSP) and desalination technologies. Thus, different models were combined aiming the thermodynamic analysis of a CSP system in cogeneration with MED and RO plants, under different conditions it would find throughout the year in the Northeast region of Brazil. The MED thermal model developed to provide an accurate description of the process was solved using a simultaneous equation solver. Detailed information about the brine and distillate flow rates and various temperature profiles were calculated. CSP and RO processes were solved using software packages. The results of the study show that the MED and RO desalination processes powered by CSP can present excellent performances, and the RO option would be more efficient in some cases.
