Energy-water nexus in East Iraq: capacity potential analysis and spatial assessment for an integrated CSP solar power & RO brackish water desalination plant in Khanaqin area

Abstract

In this research, an analysis of site suitability and potential desalination capacity for an integrated concentrated solar power (CSP) and reverse osmosis (RO) system can be established to overcome water-energy nexus problems such as water supply shortage, fossil fuel carbon emission, and increasing power consumption in Khanaqin area, East Iraq. Regarding various environmental and economic criteria, the analysis employed different methods and tools: analytical hierarchy process (AHP) method, additive weighting method for location selection (SL), and kriging interpolation with map algebra spatial analysis tools in ArcGIS software. The chosen criteria were assessed by using the rating method, and then the relative weight of each criterion was determined. Site suitability assessment results showed that only 0.05% of the study area, represented by thirteen sites, was highly suitable for the integrated CSP-RO system. Considering higher potential desalination capacity of the integrated CSP-RO system, the number of suitable sites was further refined, therefore only two plant sites were suggested for optimum desalination capacity. The current study helps to quantify factors related to establishing and operating combined CSP and RO plant, which aid for further insight investigations on solar and water resources availability of similar systems for different areas around the world.

The Iraqi Petroleum Refining Industry: A Review of Environmental Impact Assessment

“…To know whether it contains toxic components with harmful environmental effects so that it can be treated. The second is the possibility of benefiting from this sludge in other industrial fields, for example, its use after certain treatments as a chemical fertilizer in the field of agriculture as applied in some international technologies [71].…”

Construction of 3D Design Model of Urban Public Space Based on ArcGIS Water System Terrain Visualization Data

“…e researchers used the feature line method of the Courant format to obtain the temporal and spatial relationships between the water level and discharge of the river channel, and based on this, the GIS-based flood evolution visualization method was studied [18]. Relevant scholars have realized the dynamic simulation of large-scale water surfaces through dynamic texture technology based on the channel boundary search algorithm based on the section and developed a 3D visualization simulation system that can effectively simulate the flood in the river basin [19].…”
