An innovative combination between mechanical vapor compression and adsorption techniques has been
studied as a hybrid desalination system. A semi continues adsorption desalination-cooling system
employing silica gel with two adsorption beds has been proposed. The proposed system has been investigated theoretically to work under different operating conditions using a proposed simulation FORTRAN
code. The results have been compared with an adsorption desalination system to declare the benefit of
the combination. The daily desalinated water per ton of silica gel has been increased in range of
10–45% according to the driving temperature.
