Abstract: Disclosed herein are systems, apparatuses, and methods for using a sensed combustion zone temperature to continuously control combustion of a first (main) gas within an enclosed combustor. The combustor is in fluid communication with a first gas line carrying the first gas, a second gas line independent of the first gas line carrying a second (assist) gas having a higher heating value than the first gas, and air dampers providing draft or assist air. The first gas may be vapors from a production source or tank. A computer control system monitors the combustion zone temperature of the enclosed combustor as sensed by a sensor in electronic communication with the computer control system and controls the combustion zone temperature by changing a condition of a first gas line valve of the first gas line, a second gas line valve of the second gas line, and the air dampers.

Abstract: Apparatus and methods for lithium extraction from aqueous sources are described herein. Divalent ions are removed using staged membrane separation. The aqueous source is subjected to a solvent extraction process that extracts lithium. Aqueous and organic phases of streams produced by the solvent extraction process are separated using electrical and/or gas flotation separation. The solvent is de-complexed to unload lithium. Streams produced by the de-complexing may be subjected to electrical and/or gas flotation separation. Solvent de-complexing can be performed using an electrical separator. Aqueous streams are pH adjusted for return to the environment.
