Power Generation and Desalination from an Abandoned OilWell: Kalina Cycle-Driven Reverse Osmosis System

The sustainable production of potable water is inherently dependent on a stable and efficient energysource. This interdependence is crucial for fostering trust and investment from stakeholders acrossindustries, research communities, and investors. This study presents an innovative approach, integratinggeothermal energy—sourced from an abandoned oil well (AOW) in Iran, which eliminates drilling costs—with a Kalina Cycle System ۱۱ (KC-۱۱) power generation system and a reverse osmosis (RO) desalinationunit. By leveraging geothermal energy, a clean, renewable, and virtually unlimited resource, this system aimsto meet large-scale demands for both electricity and water. The KC-۱۱ was simulated using EES software,revealing that the injection of geothermal fluid can generate ۱۱۰ kWh of power efficiently at optimal pressurelevels. Simultaneously, the RO unit, modeled with WAVE software, demonstrated that a power input of ۴.۸۷kWh per ۱ m۳ is sufficient to achieve the client’s potable water requirement of ۸۰۶ m³/day. The resultsunderline the economic and operational benefits of utilizing AOW-derived geothermal energy, offering asustainable and cost-effective model for integrated water and energy production that aligns with globalenvironmental and resource efficiency goals.
