- Abstract
Socioeconomic development in many parts of the world is hampered by a lack of fresh water for potable and industrial use. The Kingdom of Saudi Arabia (KSA) relies on seawater desalination for meeting its water needs due to low per capita water availability. Desalination technologies predominantly utilize energy produced from oil and natural gas which emit greenhouse gases (GHGs), with the current policies encouraging the integration of renewable energy. KSA with its abundant solar energy resource availability has strategized decarbonization of the water sector through process efficiency improvement and renewable energy utilization. This study looks at the effect of performance ratio (PR) on the cost of desalinated water and CO2 emission reduction, when using a concentrated solar power (CSP) assisted multi effect distillation - thermal vapor compression (MED-TVC) desalination unit. The PRs chosen were 8.4,12,16, 20 and 24 based on the enhancement in the top brine temperature (TBT) from 65°C seen in commercial plants (PR 8) to 85°C and 95°C in the pilot studies. The techno-economic study showed that CO2 emissions are reduced by 42% when the MED-TVC is operated at a PR of 20 when compared with a conventional MED-TVC operating at a PR of 8.4. The cost of water production is reduced by 3.3 $/m3 when comparing CSP MED-TVC at a PR of 20 to the current commercial plant operating at a PR of 8.4. Furthermore, the solar area required to power CSP MED-TVC at a PR of 8.4 for 8 h without any Thermal Energy Storage (TES) is nearly equal to the solar area required to operate the MED-TVC at a PR of 20 with a TES of 16 h.
