Abstract

Water scarcity poses a significant challenge globally, driving the need for effective solutions in water transport and purification. This paper examines the innovative use of vapor pipelines that leverage water vapor for efficient transportation, based on the principles of evaporation and condensation. It focuses on optimizing water treatment and transmission by investigating pressure differentials that enable vapor flow from the evaporation to the condensation section under sub-atmospheric conditions. The study compares two desalination pipeline systems: an adiabatic system and a steam trap system. Findings indicate that the steam trap scenario transfers 30% to 35% more water than the adiabatic scenario, with an additional 5% collected during transit. Temperature assessments reveal that the adiabatic system maintains higher temperatures, correlating with reduced energy consumption, while the steam trap system displays greater variation in vapor velocity. Additionally, the steam trap experiences a 20% greater pressure drop, suggesting potential benefits for the adiabatic approach in specific contexts. Economic feasibility is contingent on environmental conditions, with each system facing distinct operational challenges. This study highlights the necessity of evaluating both systems based on their unique circumstances to effectively tackle the pressing issue of water scarcity. Ultimately, tailored solutions are essential for optimizing water resources worldwide.
