3- Vaper compression (VC) :
In VC seawater enters a heat exchanger to increase temperature, then spayed like
MED on a hot steam pipe. The steam collected in demister, then the compressor
pressurized the steam, and then the steam condensed by sprayed cold seawater and
produced freshwater.
VC desalination has the highest efficiency in the thermal desalination process. The
reason for that is the recirculation of the brine water to get more freshwater from the
same amount of seawater. On the other hand, VC has the highest power consumption
in thermal desalination and the lowest capacity.

2.3 Seawater Desalination Plants
Desalination plants not just RO or MSF, plant state from suction the seawater and
pretreatment it and then convert it to freshwater as previous techniques and then
move it to posttreatment, finally pumped it to use in several ways.
