“…The following constraints were applied: -In the subcritical configuration the maximum evaporation temperature T ev;max is kept 10°C below the critical point, as also suggested by Delgado-Torres [46]. -In the supercritical configuration the domain of the decision variables ðT 3 ; p ev Þ is bounded by: 1. p ev À p crit must be higher than a fixed Dp (=0.03 p crit ) and T 3 À T crit must be higher than a fixed DT (5°C) to avoid unstable working conditions; 2.…”

“…The values of 120˚C and 40 are assigned for the TBT and Nstg, respectively, regarding to the second technique. For field design, especially with large capacities, it is recommended to ensure that the Reynolds number value is between 1 and 9 Â 10 4 [25]. In the case of 1st technique, the solar field area results as 61,680 m 2 with cycle flow rate about 24.45 kg/s leading to 110 collectors for 8 loops.…”

A B S T R A C TSolar thermal power cycles assisted multi-stage flash brine recycle (MSF-BR) distillation process are thermo-economically analyzed and evaluated. In this work, the analyses are compared according to three different configurations via two techniques of solar thermal power cycles. The first technique is considered for only desalination process; however, the second is considered for desalination and electric power generation via organic Rankine cycle. Solar parabolic trough concentrator (PTC) field is considered to dominate sufficient thermal power for MSF plant. Water steam working fluid is used for a direct vapor generation (DVG); however, Therminol-VP1 working substance is used for an indirect vapor generation (IDVG) through the PTC field. Moreover, the optimized configuration from the first technique is compared with the power generation and desalination (the second technique). The comparisons are proceeding for the MSF-BR desalination plant with total productivity in the range of 5,000m 3 /d which the gain ratio is increased up to 12 with 40 stages. The thermo-economic results reveal that first technique achieves remarkable results related to the PTC area, the SPC, kWh/m 3 , and the thermo-economic product cost, $/GJ.

“…In solar PTC application with desalination, the heated oil is transferred to a BHX unit in order to generate the essential steam for the MED-TVC plant. In this sub-section, the proposed technique consists of pump unit to overcome the pressure losses, solar collector field (PTC-LS-3 type [16]) for thermal power, BHX to generate the essential vapor for the MED process and MED-PF-TVC type with 5 effects. The organic HTO across the PTC would transfer its thermal power to the working fluid (water) that passing across the BHX unit.…”
