The intensity of radiation reaches 930 W/m2 during April, 2016 in Kut city. Thus this city is suitable to use application of solar energy such as solar still. An experimental study was performed to evaluate the production of Semi Spherical Solar Still (SS-SS) with and without Charcoal. It was measured in the climatic conditions of Kut, Wasit (32o N latitude), Iraq. The still consists of square basin of length 0.3 m and area 0.09 m2 made of Aluminum. The square absorber basin is painted with black paint for maximum absorption of incident solar radiation. It was found that the productivity of Semi spherical solar still without charcoal is better than the using of charcoal at depth of basin water (dbw=1.5 & 2cm). The productivity of SS-SS without charcoal was 2.7 lit/m2 for 6 hours at total irradiation 5935 W/m2. Whereas 2.5 lit/m2 for SS-SS with charcoal at total irradiation 5845 W/m2 for dbw=1.5cm. In addition, the instantaneous efficiency reaches 58% without charcoal and 70% with charcoal at dbw=1.5cm at 3:00PM. The salinity of water before desalination in SS-SS was 999.54 ppm and becomes 4.06 ppm after desalination. It could be concluded that the semi spherical solar still can be used for distilled water production

Multiple Effect

A solar thermal-driven multiple-effect thermosyphon distillation (METD) system is proposed for waste-water treatment. The METD system consists of a series of cascaded thermosyphons that are connected by embedding the condenser section of each thermosyphon in the evaporator section of the following device. The input thermal energy is supplied by a solar collector integrated with a latent heat thermal energy storage unit. A thermal network model is developed to predict the heat transfer rates through the METD system and distilled water production rates. METD systems with various number of effects and hot end temperatures are investigated. It is found that the ratio of distilled water production to the input thermal energy increases by increasing the number of effects with no dependence on the hot end temperature. Quantitatively, a METD system with 5 effects can produce 11 kg of fresh water per hour with an input heat of 1.4 kW.

This study analyzes a technological concept for simultaneously generating power and desalinating water in a Middle East and North Africa country. An innovative, low-temperature, multi-effect desalination (LT-MED) process integrated with a concentrating solar power (CSP) plant was assessed and analyzed. A combined power and seawater desalination plant was modeled for the city of Aqaba by the Red Sea in Jordan. Parabolic-trough collectors using indirect steam generation with thermal energy storage connected with power and desalination blocks were designed. The designed plant was modeled and simulated using EBSILON Professional, a discrete energy balance simulation software, under several operating conditions, to analyze the results. An economic feasibility analysis of the combined CSP+LT-MED plant was also conducted. The simulation results showed the broad variability of the cogeneration system in terms of electricity generation and water production. The output power of the CSP plant without water production reached 58.7 MWel in June. The output power accompanied with distilled-water production with a mass flow rate of 170 m3/h was approximately 49.5 MWel. Furthermore, the number of desalination stages had the strongest influence on distillate production but limited the operational flexibility of the power plant due to the temperature gradients within the desalination stages. The distilled-water mass flow reached 498 m3/h for 10 stages. The research showed that the design successfully worked with up to €78.84 million, earned from selling the produced electricity. However, owing to highly subsidized water tariffs in Jordan (80% less than the actual cost), the integration of water desalination into the CSP plant was not economically feasible.
