“…Innovations to the layout and functioning of solar desalination processes were among the answers [13][14][15][16]. As a result, the experts converted distillers, which are within the desalination schemes, to stepped (distiller with vertical steps to increase surface area) [17][18][19], disc (distiller with rotating discs to increase the surface area and break surface tension) [20], vertical solar distillers [21], tube-shaped (tubular distiller to enhance evaporation and condensation) [22][23][24], drum (distiller with rotating cylinders inside it) [25][26][27], photovoltaic thermal [28,29], fins (distiller with longitudinal fins) [30,31], trays (distiller with suspended trays) [32][33][34], tilted [35], woven materials [36][37][38], zig-zag (distiller with corrugated surfaces to improve evaporation) [39][40][41], spheric [42,43], doublestage [44][45][46], multi-stage [47], inverted absorber [48], convex [49,50], and pyramid [51][52][53]. Furthermore, various changes in the operating conditions such as using condensers [54]…”

As is widely known, the issue of freshwater scarcity affects practically all people, and all are looking for innovative and workable ways to attempt to solve this issue. In this work, a novel method of desalination is proposed. The proposed system consists of a solar collector (PTSC), evacuated pipe (EP), condenser (CU), and separation unit (SU). The working principle of the system is heating the feed saline water using the PTSC and EP and controlling the water flow rate to control the output conditions of the EP. The produced vapor is therefore separated from salty water using the SU. In addition, the generated steam is condensed into the CU to produce a freshwater distillate. Consequently, the effect of solar radiation on the affecting temperatures was tested. In addition, the effect of using different water flow rates (6, 7.5, 10, 20, 40, and 60 L/h) inside the EP on the system productivity was investigated. The primary findings of this work may be highlighted in relation to the experiments conducted. At midday, when ultraviolet irradiance reached its highest, the EP’s water flow entrance and outflow had the largest temperature differential. In addition, the lower the water flow rate inside the EP, the higher the water temperature, the higher the evaporation rate of the system, and the greater the freshwater productivity of the system. At 6 L/h, the water’s highest temperature was 92 °C. Moreover, the best performance of the system was obtained at 7.5 L/h, where the freshwater production and average daily effectiveness of the distillate process were 44.7 L/daytime and 59.6%, respectively. As well, the productivity of EP was augmented by around 11.86% when using graphite nanoparticles. Additionally, the distilled freshwater from the system operating at the flow rate of 7.5 L/h costs 0.0085 $/L.
