| الملخص: | <p dir="ltr">This work presents a novel integration of Multi Effect Distillation with Absorption compressor (MED-AB) to reduce the energy consumption and unit water cost. The MED-AB pilot plant has been installed with a nominal capacity of 25 m<sup>3</sup>/day to validate the concept under a seawater salinity of 57,500 ppm (West of Qatar). Both pilot testing and the simulation results confirm the features of the novel design of the MED-AB process. Simulation of a commercial evaporator of 15 MIGD capacity showed that the specific energy consumption of the proposed MED-AB is calculated as 4.8 kWh/m<sup>3</sup>, which is 60% lower than the existing MED-TVC plant (13 kWh/m<sup>3</sup>). Compared to the traditional MED-TVC, the seawater feed and pumping power of MED-AB process is lower by 70% and 55%, respectively. The results confirm the minimization of the environmental impact of dumping thermal energy back into the sea and reduce the plant's capital investment, covering feed pumps size and the intake/outfall civil work. The levelized unit water cost of the MED-AB is calculated as 0.46 $/m<sup>3</sup>, which is 22% lower than that of a conventional MED-TVC desalination plant. The novel MED-AB technology would create a potential solution for the industrial applications of high salinity byproduct and solar desalination.</p><h2>Other Information</h2><p dir="ltr">Published in: Desalination<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.desal.2021.115388" target="_blank">https://dx.doi.org/10.1016/j.desal.2021.115388</a></p> |
