Seawater Steam Engine – Tehnički aspekti evaporacije morske vode u solarnom paraboličnom kolektoru

The Seawater Steam Engine (SSE) technology enables simultaneous energy and drinking water production using three natural resources (solar energy or energy of another renewable energy source, seawater and gravity) and has the potential to supply the whole world with energy and drinking water and thus stop climate changes. It is indicative that 19.06.2018. the US Department of Energy (DOE) has launched a Solar Desalination program which main goal is to research and develope a technology that can produce energy and drinking water in the same way as SSE technology, so that is more but a clear confirmation of the importance and scientific- research potential offered by SSE technology. This paper shows the technical aspects of evaporation seawater in the solar parabolic collector, which is basically a steam generator in which seawater directly enters. Seawater evaporates in the absorber tubes of the collectors, entering into a high pressure separator where two phases (steam and concentrated seawater) are separating. The steam is then drain away on the turbine, on which axle are the generators that produce electricity, after which the steam is condensed and distilled water is recived. Treating this distilled water, drinking water is produced. In order to verify the application of SSE technology in the world, four locations have been selected: Miami (USA), Vis (Croatia), Dubai (UAE) and Kunigami (Japan), which are in different climatic conditions and with different values of the dominant input parameter system, a direct solar radiation (Miami: 1491 kWh/m2a, Vis: 1578 kWh/m2a, Dubai: 1605 kWh/m2a and Kunigami: 957 kWh/m2a). The calculation of the required power of SSE technology was made by a linear correlation method, by comparison with the results obtained for the island of Vis and results are given for power per population, heat production and production of drinking water. For Miami 15.1 MW, 434 kWh/m2a, 1.22 m3/m2a ; for Vis 14.3 MW, 459 kWh/m2a, 1.29 m3/m2a ; for Dubai 13.6 MW, 467 kWh/m2a, 1.32 m3/m2a ; an for Kunigami 23.6 MW, 278 kWh/m2a, 0.78 m3/m2a ; respectively ; which is very important research results. Namely, they show that SSE technology can be very economical in locations with relatively small amounts of global solar radiation, with a relatively clean atmosphere and relatively large amounts of direct solar radiation, such as the Miami and Vis locations.
