This SCS paper covers the need for lithium and how the oil industry can help supply it. Oil field brine extraction is a naturally occurring aspect of oil and gas production. In some cases, underground reservoirs of saline water can hold substantial concentrations of dissolved lithium. The author takes us through the environmental issues with lithium extraction from brines and factors to consider, such as the brine’s characteristics, economic aspects, environmental implications, and regulatory requirements.
He describes approaches generally classified into adsorption, ion exchange, and solvent extraction. Then covers technologies to isolate and recover lithium from the brine along with the techno-economics. He closes with the support of environmental consultants and some interesting pilot projects underway.
Environmental consultants play a crucial role in supporting lithium extraction from oil field brines by helping to conduct the process in an environmentally responsible and sustainable manner. Consultants bring expertise in adopting best practices and technologies for mitigating environmental impacts associated with brine extraction and lithium processing. Incorporating environmental considerations in the early stages of project planning can contribute to maintaining sustainable practices throughout the entire project life cycle. Environmental consultants and engineers can offer a range of services for evaluating direct lithium extraction from oil field brine.
