Abstract: . . . storage fluid, for the purpose of supplying the energy required for a multi-effect (MED) distillation plant installed at the PSA. With this configuration, a performance ratio (kg of distillate per 2,326 kJ heat input) of 10 was obtained. With the goal of improving that value, two procedures for recovering heat in the MED unit were studied, thermal compression (which is usually used in conventional MED plants) and absorption heat pump technology, which upgrades low temperature heat with much higher second . . . . . . future – Seven years of experience at the Plataforma Solar de Almería (Spain), Desalination 108, pp. 51-58, 1996.

The total volume finally chosen is based on the response time required by the gas boiler and the absorption heat pump to reach nominal operating conditions. The use of two tanks enables the solar contribution to be increased . . . . . . Coast researchers seek to demonstrate SWRO affordability, Desalination & Water Reuse 14(3), pp. 10-18, 2004.
