Improving seawater desalination and seawater desalination brine management

Water scarcity is an increasing problem globally. Seawater desalination is increasingly being relied upon as a means of mitigating the problem of water scarcity. However, seawater desalination has costs associated with it: capital costs, cost of energy to desalinate and environmental costs from the discharge of high salinity brine. Efficient and cost-effective seawater desalination and desalination brine management systems are necessary to make seawater desalination a sustainable scalable process. This work seeks to improve seawater desalination and seawater desalination brine management in several ways. For the first time, the thermophysical properties of seawater have been characterized as a function of pressure across the full desalination operating regimes of temperature, salinity and pressure. Functions that allow accurate thermodynamic least work of desalination and seawater flow exergy analysis have been developed.
