Hi Nada, why not explore the 'thin layer' evaporation of seawater using fine bubbles (microbubbles at 25um) of very hot air in a recirculated fluid flow.  As a proof of concept we proved we could evaporate a supply of tap water at ~40C, at a rate of close to 0.75 lph using a Nikuni fine bubble generator and a hot air blower.  The power consumed was less than 1kW. How does it work?  We heat the gas phase not the fluid. The clusters of hot 25um bubbles of air at ~500C require a lower energy input than heating the fluid.  Worth exploring?  Contact Aeration & Mixing - enquiries@aerationmixing.co.uk.
