Abstract: The present disclosure includes systems and methods for extracting a target element, such as lithium, from a brine. For example, some aspects include a method of extracting lithium including mixing a first brine with an extraction agent to form a first solution having a lithium complex, the lithium complex including lithium bound to the extraction agent. The method can further include extracting the lithium from the first solution and recycling the extraction agent to be used in a further extraction process. In some aspects, extracting the lithium from the first solution includes adsorbing, via an adsorbent media, the lithium complex from the first solution, removing the lithium complex from the adsorbent media, and separating the lithium from the extraction agent in the lithium complex.

Abstract: Methods for treating a gaseous stream are described herein. A method for treating a gaseous stream, includes contacting a gaseous stream comprising a mixture of hydrocarbons with organosilica particles at a temperature of 60° C. or less and a pressure of 0.1 MPa(g) or more to capture at least a portion of the hydrocarbons from the gaseous stream and to obtain a treated gaseous stream. The hydrocarbon dew point value of the treated gaseous stream is lower than a hydrocarbon dew point value of the gaseous stream prior to being contacted with the organosilica particles.

Abstract: Methods for regenerating a bed of organosilica particles and producing a treated gaseous stream are described herein. A method for regenerating a bed of organosilica particles includes introducing a heated regenerate stream to a bed of organosilica particles comprising captured C3+ hydrocarbons under conditions sufficient to remove at least a portion of the captured C3+ hydrocarbons from the organosilica particles; and introducing a cooled regenerate gaseous stream to the heated bed of organosilica particles. The regenerated organosilica particles are used to treat additional gaseous streams.
