“…This result is much greater than that produced by a conventional CSP plant. In reference [13], for a plant producing electrical power close to 50 MW, the fresh water production is equal to 14,300 m 3 /d having the same GOR (9.8) considered in this paper and the same thermodynamic conditions of the steam extracted (p sat = 0.31 bar, T sat = 70˚C). In reality, in this conventional situation, the steam extracted from the LP turbine (16.91 kg/s) is probably limited by the electricity loss due to the steam extraction.…”

“…In order to compare the fresh water production with data presented in literature (for a 50 MW el conventional CSP plant [12,13,19,20,23,24]), the scale up of the DEC plant offers a production rate equal to 22,100 m 3 /d, for 24-h continuous plant operation. This result is much greater than that produced by a conventional CSP plant.…”

“…Elaborating on this electrical loss in the conventional CSP, the data reported in [13] can be estimated in the range of 1.8% when 1.5 kWh (electric) per m 3 of freshwater is assumed. In fact, for a 50 MW el conventional CSP plant, 14,300 m 3 /d of freshwater are produced requiring 21,460 kWh el /d for desalination.…”

“…In fact, the main disadvantages of conventional (oil HTF-based) CSP + D are that the desalination integration is technologically intrusive with CSP. Namely that the LT-MED process decreases the net electric power of the CSP [12,13]. This is due to the steam extraction, usually from a low pressure (LP) turbine.…”

A B S T R A C TFresh water and electricity production in desert areas via the use of solar radiation represent examples of sustainability. The concentration of solar power by means of parabolic trough (PT-CSP) technology has a great potential not yet exploited in the realm of renewable energy production. A new technology for the solar energy section is being proposed by the authors which uses air as a working fluid. The use of air allows the cycle to be coupled with an inter-cooled compression section and a re-heated expansion section which is called Discrete Ericsson Cycle, (DEC-based plant). The paper presents an integration of such a CSP-DEC plant with desalination: where freshwater is produced according to a Low Temperature Multi Effect Distillation (LT-MED) technology. The LT-MED plant operates on the heat from the air coolers in the inter-stage cooling of the DEC-based plant. This heat is normally expelled to atmosphere. In fact, the heated air has the same temperature ranges required for the operation of the LT-MED desalination technology. This provides an efficient integration of energy for desert applications. The most important feature of this new solar energy plant is that the thermal needs of desalination in DEC-based plants do not interfere with the electricity production of the plant as is the case for current conventional PT-CSP plants which use diathermic oils as Heat Transfer Fluid (HTF). When the performance of the CSP DEC-based plants, integrated with the LT-MED technology, are compared to conventional CSP plants, they show an increased efficiency in terms of fresh water production per unit of energy produced. Thus, fresh water production can be considered as a valuable addition to the plant.

The design of a multiple-effect distillation (MED) system is presented, and the results for partial load operation of a single-effect distillation unit are presented. The MED is designed to be driven by solar energy, and thus the dynamic performance and partial load operation production are of interest. Two operating modes are considered in the analysis, with and without the use of a flow distributor. Various tests were performed varying the heating steam flow rate and the intake seawater flow rate. Results are presented as a function of the performance ratio, representing the amount of distillate produced per unit mass of steam input. Results indicate that a higher performance is obtained with the use of the flow distributor.
