Analysis on Interference Factors of Lithium Extraction from Produced Water of Gas Field
Amidst the swift ascension of China's new energy sector,the demand for lithium has surged past the capacity of traditional lithium ore extraction to supply the market.Consequently,the focus has shifted towards the extraction of lithium from liquid sources,including salt lake brines,subsurface brines,seawater,and produced water from gas fields,which have garnered considerable attention.To date,a suite of lithium extraction technologies centered on precipitation,solvent extraction,adsorption,membrane separation,and electrochemical methods has been developed for the processing of salt lake brines.In contrast,studies on lithium extraction from gas field produced water are relatively scarce.This paper presents an analysis of the lithium extraction process from gas field produced water,taking into account the interfering factors commonly encountered in the extraction from liquid lithium deposits such as salt lake brines,subsurface brines,and seawater.The objective is to offer insights and guidance for the development of lithium extraction technologies specifically tailored for gas field produced water.The study underscores the need for innovative,cost-effective,and environmentally friendly approaches to address the challenges associated with lithium recovery from these complex liquid sources.
