摘要

This study presents a comprehensive evaluation of a high-pressure desalination pipeline system designed to evaporate seawater at elevated temperatures and facilitate its transfer to designated locations through pressure differentials. The system utilizes energy derived from waste heat generated by a cement factory. A detailed case study examines a 26 km transmission line from the Khuzestan Cement Factory to Mount Asmari and an 84 km line to Garreh, with estimated daily water production of 12,465 m³ for Mount Asmari and 6,685 m³ for Garreh. To validate the system’s performance, a laboratory model was developed and subjected to rigorous testing under varying temperatures ranging from 110 to 150 degrees Celsius, with water throughput measured between 14 kg/hour and 46 kg/hour. Comprehensive testing ensured alignment of experimental data with theoretical calculations, revealing discrepancies of no more than 10%, thereby reinforcing the operational reliability of the system. Furthermore, a comparative analysis of the proposed desalination technology against existing water treatment and transportation methods underscores its numerous advantages, positioning it as a viable and efficient solution for addressing global water scarcity challenges. This research highlights the potential for sustainable freshwater production and the innovative integration of waste heat utilization in desalination processes.
