“…On the basis of the costs of $108k reported elsewhere for a 1000 kgadsorbent desalination system [29], the utilization of the SIL material can enable reduction of the capital cost of ~20%. This improve further an already economically attractive technology such as adsorption desalination [53,54]. However, this benefit requires further and more detailed assessment since it can be counterbalanced by a cost of the composite higher than silica gel.…”

The composite material 1-ethyl-3-methylimidazolium methanesulfonate ionic liquid in Syloid AL-1FP silica shows unprecedented water vapor sorption equilibrium properties. Equilibrium data were recorded at different loads of ionic liquid in the silica support (from 1.8%w to 60%w). At loadings >1.8%w, all the composites show type 3 isotherm, therefore conserving the vapor-liquid equilibrium of the bulk ionic liquid/water binary system but with increased dependence between temperature and water adsorbed. This feature makes this composite material particularly suitable for thermally-driven technologies. The composite 60%w 1-ethyl-3methylimidazolium methanesulfonate ionic liquid in 40%w Syloid AL-1FP silica shifts the performance of sorption desalination and drying processes at the unprecedented working capacity of 0.46 gwater/gsorbent (desalination) and 0.82 gwater/gsorbent (drying).

“…The adsorption-desorption process is a physical and/or chemical surface phenomenon where the molecules/atoms of a substance (the adsorbate) are attracted to and retained on the surface of a solid or liquid material (the adsorbent), resulting in a higher concentration of the molecules/atoms on the surface. It has been used as a separation process for mixtures like seawater solution into two streams [71,72]. The adsorption-desorption process has been deployed in many applications such as separation processes, air-conditioning, and brackish water desalination.…”

“…Theoretical, empirical, and semi-empirical models have been used to model the amount of adsorbate adsorbed on the surface of the adsorbent [83]. Adsorption is an exothermic process, and the heat of adsorption can be calculated from Equation 2; it depends mainly on the characteristics of the adsorbent and adsorbate in addition to temperature, pressure, and the concentration of the adsorbate, while desorption is an endothermic process that depends on the same parameters [71].…”

Several regions are confronting a severe scarcity of fresh water due to the gap between supply and demand. They strive to bridge that gap by depleting nonrenewable water aquifers and expanding centralized energy-intensive desalination technologies. Continuing to adopt the same unsustainable approach could deplete the water aquifers and increase the consumption of fossil fuel and the ecological impact on air, water, and land. However, the traditional paradigm of centralized desalination systems could be shifted by increasing the utilization of renewable distributed generation, which can be coupled with emerging desalination technology such as adsorption desorption desalination (ADD), which has autonomous and resilient attributes that can contribute to the sustainability of decentralized fresh water supply in the future. In this work, three commercialized desalination technologies were reviewed and compared with emerging ones to explore the most economically and environmentally efficient systems within the context of decentralized water production. The well-known configurations of ADD were evaluated and compared with sea water reverse osmosis (SWRO), which is recognized as the principal commercialized desalination technology worldwide. The quantitative case study methodology was used by investigating four centralized seawater desalination plants in Saudi Arabia (SA) with their associated pipeline systems from the energy consumption point of view to determine the applicability of implementing ADD technology in SA and similar arid areas. The study reveals that adopting decentralized ADD technology coupled with renewable energy sources could reduce the specific energy consumption from 4 kWh/m3 to less than 1.38 kWh/m3. Combining reduced energy consumption from desalination plants and elimination of supply pipelines could potentially result in a significant reduction in energy consumption and carbon emissions. Finally, the study may be useful for researchers working on enhancing ADD processes, as well as technology users who would like to implement the most efficient ADD configurations. Additionally, it may initiate a direction of utilizing the results of original critical reviews as a methodology to develop the applied technologies.
