摘要

Oil and gas field-produced water (PW) has emerged as a key source of lithium and rare earth elements (REEs). This study investigates the significant variance in lithium concentrations across different oilfields, with the Williston Basin in North Dakota having an average lithium content of 219.97 ppm. To be economically viable, lithium concentrations in produced water are required to exceed a minimum of 100 ppm. A novel approach integrating membrane filtration with economic feasibility analysis is proposed, offering a scalable solution for lithium recovery from highly saline PW. Experimental data obtained from Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) demonstrates the effectiveness of this method, with recovery rates of up to 85% for lithium and 90% for salts under optimized conditions. This research evaluates the comparative performance of advanced recovery technologies and proposes a method that not only enhances the lithium extraction but also ensures sustainable PW management. Beyond technological developments, this study looks at the economic potential of petroleum and energy companies. The research work emphasizes the economic potential associated with the market value of lithium and the widespread use of salts in the Midwest of the United States. Economic recovery solutions could allow petroleum companies to balance expenses linked to water recycling and disposal, resulting in increased revenue streams. This research not only contributes to the subject of recovery technology but also proposes options for long-term economic growth in the petroleum and energy sectors. The study concludes that members filtration techniques could reduce water disposal costs by 30% while increasing revenue streams through lithium and salt recovery.
