Freezing Desalination with Thermal Energy Storage System Based on LNG Cold Energy

Translated Abstract

This　work　proposes　a　LNG　cold　energy　recovery-freezing　desalination-thermal　storage　coupling　system,where　the　LNG　cold　energy　drives　an　organic　Rankine　cycle　to　generate　power.Simultaneously,seawater　is　subjected　to　cryogenic　centrifugal　desalination,and　the　desalinated　ice　produced　is　stored　as　a　thermal　storage　medium.The　thermodynamic　and　economic　analyses　of　the　system　are　conducted.The　results　show　that　the　daily　freshwater　production　of　the　system　is　119.66　t,with　a　net　output　power　of　52.10　kW.The　investment　payback　period　is　3.23　years,and　the　desalination　cost　is　0.48　USD·t-1,significantly　lower　than　the　cost　of　traditional　reverse　osmosis　desalination.
